Panasonic Lumix DC-GH5S First Impressions Review

Panasonic GH5s is the choice of a professional. Review

Panasonic is certainly one of the leaders in the production of equipment for film and video production. Once upon a time, I started shooting video on Panasonic cameras - first it was an analog film camera M3000, then an M9000 in S-VHS format, then a professional F-70. Later, already in the digital era, the legendary miniDV camera Panasonic DVX-100. Nowadays the company is also at the forefront not only in the professional sector, but also in the much larger segment of budget videography. Everyone is well aware of the GH line of cameras, among which is the iconic GH4, which was one of the first among hybrid cameras (if not the very first) to allow you to shoot 4K UHD video directly to the internal memory card. But, in my opinion, the biggest breakthrough came with the release of Panasonic Lumix GH5. This camera has made it possible to shoot professional quality videos on a budget device.

Well, today we will look at an even more video-oriented camera, the Lumix GH5s, although it would seem that there is much more to it?

The original Lumix GH5 doesn't have many downsides. One of them is not the most advanced tracking autofocus for video shooting - a big problem, of course, for amateurs, but for people with at least some experience, this parameter does not matter at all. But the second drawback is quite significant - it works poorly at high ISOs. Basically, the limit for the GH5 is 3200 ISO, and I know many people don't go higher than 1600.

GH5s, first of all, solves exactly this problem. There is a completely different matrix with a resolution of 12 MP. Each sensor pixel has a larger physical size and, therefore, is able to receive more light. Therefore, the light sensitivity has increased by about 2 steps, that is, I would call 12800 ISO working for this camera. This is an excellent indicator not only for a Micro 4/3” system (for Micro 4/3” this is phenomenal), but also for cameras with a larger sensor size. Not all full-frame cameras are capable of properly shooting video at such a sensitivity.

Another feature of the new matrix is its multi-aspect nature. Sorry for this term - I don’t know how to adequately translate it into Russian.

How is an image usually formed with an aspect ratio such as 16x9 for video shooting on all hybrid cameras? In this case, the upper and lower areas of the matrix are simply not read, so when shooting video, a crop factor appears, although not large. On the GH5s everything is different, the sensor is slightly larger than required by the micro 4/3” standard, inscribed in the image circle created by the lens, in such a way that at any aspect ratio the maximum possible area of the sensor is used. In practice, this means that the video will be slightly wider when using the same lens than on the GH5. The difference is small, but for some it can be very important. Let me remind you that for professionals there are no trifles.

Cinematic DCI 4K, that is, video with an aspect ratio of 17x9 on the GH5s can be recorded at any number of frames per second, that is, not only 24 fps, as on the GH5, but also 25, 30, 50 and 60. Otherwise, by format recording, the capabilities are the same: up to 400 Mb/s 4:2:2 10 bits in 4K up to 30 fps, 4K 50-60 fps 8 bits 4:2:0 with a bitrate of 150 Mb/s - this is on the internal card memory. With an external recorder, any resolution at any frame rate can be recorded in 4:2:2 10-bit via full-size HDMI.

V-Log is installed by default on the GH5s. The ability to record HLG video has also been added. Panasonic's logarithmic mode is not bad, after conversion to Rec709 the shades are not distorted, the skin color is correct. As for me, the saturation of red is slightly too high, but this is easy to combat. Hybrid log-gamma is designed for recording video for playback on TVs and monitors with HDR, that is, capable of reproducing high dynamic range. This is not a very popular feature yet due to the high cost of these same TVs, but it will certainly be useful to someone.

Here, pixel-by-pixel reading is used naturally, because there is simply no excess resolution for oversampling. This may somehow affect the detail, but let's remember professional movie cameras. In the conditions of “big cinema”, when the cost of equipment no longer matters, no one is stopping the same ARRI or RED from developing and installing matrices with a resolution of 100MP or more in their cinema cameras in order to obtain oversampling even for 8K. However, they don’t do this - so does this make any sense?

I keep talking about shooting in 4K, but the GH5s shoots FHD video just fine. Here, it seems to me, oversampling from 4K is used and the video quality is simply excellent, both in terms of detail and color rendition, in the absence of any distortion in the form of moire and aliasing. Of course available for FHD 10 bit 4:2:2, F-Log and everything else. Super slow-motion shooting is possible at a frequency of up to 240 fps, up to 180 fps, the video quality is very high, after which a drop in detail is already noticeable.

In appearance and ergonomics, the GH5s is completely identical to its younger brother, the GH5; the only difference is that some elements are painted red. Excellent touch screen, with the ability to navigate the menu, rotates in all planes. Many people like this implementation, although it also has its drawbacks. Well, for starters, since when did everyone become bloggers, that everyone needs to film themselves and see on the screen? For example, this just bothers me. And then, if you have headphones or an HDMI connector connected, they block and partially cover the screen.

In 2018, many new cameras were released - full-frame and with crop sensors - most of them have flagship or near-flagship status. All manufacturers boast a viewfinder with a resolution of 3.69 million dots (this is not megapixels, in fact the resolution is 1280x960 pixels, that is, about 1.2 MP). So, the GH5s had such a viewfinder a year ago, and its frame rate can reach 120 fps. I know that many who shoot video with hybrid cameras do not use the viewfinder and in vain. Firstly, it is much more convenient to control exposure and focus, because the screen is closer to the eye and there is no light from external sources, and secondly, when shooting handheld, a third point of camera fixation is added (right, left hand and head). In this form, I shot at an equivalent focal length of 200mm and got a stable picture. Even despite the absence of a matrix stabilizer.

Yes, there is no matrix stabilization, and Panasonic was criticized by many for this. But there are several reasons for this. The first, which the manufacturer himself insists on, is that the camera is intended for professionals, and when using professional stabilization systems, when it is necessary to compensate for sudden movements, the matrix stabilizer may conflict with an external stabilizer. This makes some sense. The second reason - these are my assumptions - is that an enlarged matrix with large vibration amplitudes may fall outside the image circle formed by the lens. And the third, important reason is that installing a matrix stabilization system would add cost to the already expensive (for a micro 4/3”) GH5s system.

The average cost of the new Lumix GH5s is now just under 170 thousand rubles per body. But, since the model has been on sale for quite a long time, you can look for promotions, various discounts and buy the camera cheaper.

Who is the Panasonic Lumix GH5s suitable for? Well, firstly, for professionals who shoot documentaries, corporate films, advertising, high-budget weddings (why not?), when not only editing is done, but also normal video post-processing. Even film shooting, especially since this is the only camera on the market that can work correctly with anamorphic optics. Full-fledged cinema lenses are even produced under MFT. Secondly, for those who want to develop. Who wants to step forward and get truly professional quality videos for their projects.

Panasonic Lumix DC-GH5S First Impressions Review

The Panasonic GH5S is a video-oriented Micro Four Thirds camera with an unusual resolution for 2018, which is 10.2MP. The previous GH5 was already focused on video, but the new S version offers even more features and incredible light sensitivity. The camera can shoot DCI and UHD 4K, capturing images from the entire sensor surface at up to 60fps.

The ability to shoot DCI 4K at up to 60p without cropping is the most obvious difference between the new and standard GH5, but the differences run deeper:

Main technical characteristics

Large-sized sensor with dual signal amplification design and flexible aspect ratio change system without cropping
10.2MP maximum usable area. Full 12.5MP resolution
DCI or UHD 4K at up to 60p
10-bit 4:2:2 internal recording at up to 30p
8-bit 4:2:0 native 60p recording or 10-bit 4:2:2 recording via HDMI
Full HD at up to 240 fps with additional crop above 200 fps
Hybrid Log Gamma Mode
ISO 160-51200 (80-204800 extended)
Autofocus down to -5EV with F2 aperture
3.68MP (1280 x 960 pixels) OLED viewfinder with 0.76x magnification
1.62MP (900 x 600 pixels) fully articulated display
14-bit RAW
11 fps (7 with autofocus) or 12 fps in 12-bit mode
USB-C 3.1

Lower resolution allowed for larger physical pixel sizes. This means that the camera will be able to shoot more detailed video in the dark with minimal noise.

Differences vs GH5

Larger 10.2MP sensor compared to standard sized 20.2MP Four Thirds sensor
Best performance of dual ISO boost system
Fixed sensor without internal stabilization, allowing the use of professional stabilization systems
DCI 4K can be shot at 59.94, 50, 29.97 and 25P (GH5 limited to 23.98/24p only)
AF is designed to perform in low light conditions (-5EV vs -4EV)
14-bit Raw
VLog-L is immediately installed in the camera
Time code in/out connector
“Like709” and “V-LogL” color profiles
Microphone jack offers phantom power
Corrected display LUT available in playback mode
Viewfinder displays images at 120fps

Apart from these changes, the GH5S retains the rest of the GH5's capabilities, including various codec settings and tools such as vectorscopes and preview for anamorphic video, Log and Hybrid Log gamma.

As with the GH5, Panasonic recommends using memory cards rated V60 or faster for shooting 400MB video. However, the V60 standard is vague enough that some V60 memory cards are not enough to satisfy the camera's recording speed. The company says it's best to use memory cards made by Panasonic or the V90 standard and stick with reputable manufacturers with a proven track record of producing fast cards.

Image Sensor Features

The GH5s uses a chip that natively reads DCI or UHD 4K data, meaning one pixel on the sensor is used to capture every pixel in the final frames. The sensor, like on the GH1 and GH2, is too large. This means it can shoot in a variety of aspect ratios while taking full advantage of the lens' image circle, rather than simply cropping the frame.

This means the GH5S will offer the maximum field of view when using any M4/3 lens.

The only downside is that using a larger region may limit the use of APS-C and Super35 lenses when combined with adapters such as SpeedBoosters 0.61x.

Dual Gain

Panasonic describes the GH5S as the first mirrorless camera to feature "Dual Native ISO", which is standard technology in professional camcorders. Such chips have two readout modes, one that maximizes dynamic range at low sensitivity levels, and a second designed to minimize noise at higher ISO settings. The second mode changes the “conversion factor” by significantly increasing the output voltage per pixel. This is something we first saw in Nikon cameras.

The only difference between Panasonic's approach is that it allows you to manually select which mode the camera will operate in, while other brands simply automatically switch between these two signal amplification circuits.

Low number of pixels

Another thing that helps give the GH5S a boost in low-light performance is the use of fewer pixels. This allows for larger pixels that can capture more light in low light conditions.

However, low resolution indicates less detail. Most high-resolution cameras read the entire sensor area, capturing a lot of detail, and then downsample to 4K, but the original frame contains a lot of fine detail, which is effectively preserved when converted, whereas a low-resolution camera does not see the fine details details at all.

However, the speed of reading and processing, as well as problems with heat dissipation, do not allow all manufacturers to use video resampling, so they have to resort to tricks by performing interlaced image reading during video recording or using other ineffective algorithms.

The most obvious advantage is that fewer pixels can be processed quickly. This speeds up image reading from the sensor. So while the latest processors are fast enough to generate frames from high pixel count oversampling, there is a risk of rolling shutter. Having fewer pixels, the GH5S should have less rolling shutter.

Having a lower pixel count also means the GH5S can use an anti-aliasing filter, which reduces the risk of moire in videos, without having to worry about resolution limitations in photos.

The wider dynamic range obtained from larger pixels requires greater bit depth to store this additional data, so the GH5S can shoot 14-bit RAW files.

No stabilization

From a photographer's point of view, this may seem strange, since the previous model had an excellent built-in stabilizer. Panasonic says this makes sense. The sensor shift system operates a "floating" sensor using a series of electromagnets. Even when they are turned off, the sensor does not lock in place. The electromagnets simply stop trying to correct the jitter. This has a side effect when using professional stabilizers. The sensor may shake unpredictably and the system may not function properly.

For high-quality video, Panasonic says its users would prefer to use dedicated gimbals and dollies rather than internal stabilization, which means physically locking the sensor in place to avoid unwanted interactions between these systems and the floating sensor.

However, regardless of what Panasonic says, there is also a physical limitation imposed by the size of the sensor. Since the sensor is adjacent to the edge of the image circle, there is simply nowhere for it to move. This is confirmed when digital stabilization is turned on. The camera performs a small crop to be able to shift the frame for stabilization.

4K Video Modes

The GH5S can shoot all the modes that the GH5 offers, but now the bitrate is increased and the DCI mode, which was previously limited to 24fps, is now expanded to 60fps.

The Panasonic Lumix DC-GH5S camera is aimed at film and video production professionals

Panasonic Lumix DC-GH5S camera resolution is 10.2 megapixels

Panasonic took advantage of CES 2018 to unveil the Lumix DC-GH5S, which the manufacturer describes as a “hybrid digital mirrorless camera.” Designed for film and video professionals, Panasonic says the camera offers "the ultimate in video capabilities and enhanced image quality," delivering "the highest light sensitivity and the best image quality ever in the Lumix family of cameras."

The camera is based on a new Digital Live MOS image sensor with a resolution of 10.2 megapixels in Four Thirds format (17.3 x 13 vv) with Dual Native ISO technology. The data is processed by the Venus Engine 10 processor. This combination made it possible to obtain a light sensitivity range of ISO 160-51200, expandable to ISO 80-204800.

Shooting in 4:3, 17:9, 16:9 and 3:2 aspect ratios is available, as well as RAW photography in 14-bit format. The manufacturer notes high focusing and burst speeds. The latter reaches 12 fps.

The Lumix GH5S supports timecode synchronization, for which there is a Time Code IN/OUT connector and a coaxial cable included. The camera can act as a timecode generator for other GH5S cameras and professional camcorders. This makes the crew's work easier, especially when using multiple cameras, by allowing image and sound to be synchronized between multiple devices.

Video mode supports Cinema 4K resolution (4096x2160 pixels) and 4:2:2 chroma subsampling and 10-bit recording. Supports 4:2:2, 10-bit, and 400 Mbps All-Intra when shooting in 4K at 30, 25, or 24 fps, and when shooting in C4K at 24 fps. s, as well as at a bit rate of 200 Mbps All-Intra when shooting in Full HD resolution. There is no limitation on the duration of video recording. In Hybrid Log Gamma (HLG) mode, the camera is 4K HDR compatible. The ability to shoot in C4K/4K resolution at up to 60 fps and in Full HD resolution at up to 240 fps allows you to get a slow motion effect. Finally, 4K HEVC video recording is possible and can be played back on compatible equipment such as Panasonic 4K HDR TVs.

The camera equipment includes an OLED electronic viewfinder with a resolution of 3.68 million dots with a magnification of 1.52x (0.76x in 35mm camera equivalent) and 100% frame coverage. The 3.2-inch diagonal movable touchscreen LCD display has a resolution of 1.62 million dots. In addition, there are Bluetooth 4.2 and Wi-Fi IEEE 802.11ac modules, a USB 3.1 Gen 1 port, an HDMI output, connectors for an external microphone and headphones.

The camera body is made of magnesium alloy. The camera is protected from moisture and dust and remains operational at temperatures down to -10°C. For removable media there are two slots supporting SD, SDHC, SDXC and UHS-II Video Speed Class 60.

The camera weighs 660 g and its dimensions are 139 x 98 x 87 mm. Without recharging the battery, you can take 440 shots. An additional reserve of autonomy is provided by the separately purchased battery grip DMW-BGGH5.

The camera will go on sale February 2 for $2,400. Its appearance on the Russian market is expected in April at a price of about 170,000 rubles.

Panasonic Lumix GH5S vs GH5: What's new?

Introduction

The Panasonic GH5 is one of the best camcorders out there, but it's a hybrid camera that aims to meet the needs of photographers and videographers. But what could be achieved by focusing on one core function? The GH5S is the product of Panasonic engineers who faced this issue. They created a device based on the GH5, focusing on video shooting.

Low light

The new sensor is equipped with a double signal amplification system, which allows you to increase light sensitivity with a minimal increase in noise. Panasonic's Dual Native ISO technology has previously been used in professional camcorders. The sensor uses two separate sensing circuits that operate differently at different ISO levels. This allows you to maximize dynamic range and maintain image clarity while reducing noise.

The first scheme works in the ISO range 160-640. When increasing the value to ISO 800, the automation turns on a second circuit, which is optimized to produce minimal noise at higher sensitivity values. This significantly improves image quality compared to the base GH5 model.

Multi-format sensor

Previously, such sensors, as well as Dual Native ISO technology, were used in Panasonic camcorders. It's great to see this solution implemented in the GH5S. The overall camera resolution is 12.5MP, but the sensor size is larger than the image circle created by M4/3 mount lenses. At different aspect ratios, the camera maintains the maximum possible resolution, which is 10.2MP in a 4:3 aspect ratio. This allows you to record UHD 4K video without cropping, offering the widest possible viewing angle you can get from the lens you're using.

At any aspect ratio, be it 17:9, 3:2 or 16:9, the camera captures a wide image, unlike a standard 4/3 sensor which tends to crop out a lot. You can find out more about this in our article First comparisons of the GH5s and how the new MFT sensor works.

DCI 4K at 60/50p

The GH5 is capable of recording UHD 4K (3840 x 2160) at 60 or 50 fps, but DCI (4096 x 2160) is only available at 24 fps. The video-centric GH5S can shoot in DCI at 60, 50, 30, 25 and 24 fps. Thanks to the larger sensor, the viewing angle on the GH5S is noticeably wider than on the GH5.

14-bit Raw, but slow motion

The GH5S now has the ability to save 14-bit Raw files. This allows you to expand the dynamic range. The camera can shoot at 7fps with autofocus, compared to 9fps in 12-bit mode on the GH5. The Panasonic GH5S can be switched to 12-bit mode, but the shooting speed will only increase to 8fps with continuous autofocus.

No stabilization

Sensor shift-based image stabilization is a great solution for photographers and videographers, but doesn't make much sense for professional videographers who use external stabilizers. The GH5's floating sensor design can interact with the gimbal even when turned off, so removing it completely solves this problem. This is another solution aimed at professional videographers rather than photographers.

Additionally, the GH5S's image sensor mount allows for improved heat dissipation. The increased size to accommodate different aspect ratios does not allow for sensor shift-based stabilization.

Frame frequency

Various frame rate settings on the GH5S include 240fps in Full HD and 60fps in DCI and UHD 4K. This allows you to shoot in slow motion by reducing the frame rate to 24 or 60 per second. The GH5 only offers up to 180fps Full HD and 60fps 4K in UHD mode only. This allows for up to 10x slow motion in Full HD video with the GH5S, although it's worth noting that when frame rates go above 200 per second there is a reduction in video quality and additional cropping.

Timecode sync port

Timecode synchronization is supported using the flash sync connector on the camera body. This makes it easier to use the GH5S when working with multiple cameras, when files are added to an editor such as Final Cut Pro, time codes are automatically recognized and synchronized.

A special adapter for the flash sync connector is included with the camera.

Working with a microphone

While the GH5 offers a standard microphone jack, the GH5S has a more robust option that supports phantom power, allowing it to be used with a wider range of audio sources.

120fps viewfinder

The GH5S uses the same 680,000-dot viewfinder as the GH5 with one key difference. The frame rate has been increased to 120 image updates per second. This is probably due to a decrease in the number of pixels read from the sensor, since the resolution of the GH5S matrix is almost 2 times lower than the GH5.

Built-in V-LogL

V-LogL was added to the GH5 following the release of an optional software update. This is a standard feature on the GH5S. LUTs can be loaded into the camera using an SD card, making it possible to view gamma-corrected and color-corrected images on camera as they would appear after editing on a computer.

Various autofocus characteristics

Panasonic claims the GH5S can autofocus in light as low as -5EV. It's about as dark as a moonlit night without other light sources. However, this came at the cost of reduced autofocus speed. The GH5 can focus in 0.05 seconds, while the GH5S slows this down to 0.07 seconds.

Cost of lower resolution

The most obvious difference between the specs of both cameras is the sensor resolution: the GH5S offers 10.2MP resolution compared to the GH5's 20.3MP. This is enough to provide the 4K resolution required for video shooting, and also allows Panasonic to use larger pixels. Combined with 14-bit mode, this gives a dynamic range advantage, but it also means the camera has to read fewer pixels. This should reduce the rolling shutter effect.

But in addition to these positive features, there are some disadvantages.

The low resolution of the sensor means that it cannot offer high resolution when using anamorphic lenses. The GH5 camera offers 6K shooting. Also, due to insufficient resolution, the camera does not have a 6K Photo mode, which is available in the GH5.

Conclusion

With the release of the GH5S, Panasonic engineers decided to make a hybrid camera with a clear bias towards video shooting. While the two cameras are almost identical on the outside, Panasonic has made some interesting moves to optimize the specs to significantly improve video quality. In low light, the GH5S can compete with the full-frame Sony A7S II, which has twice the image sensor. This is an amazing result for such a camera.

Panasonic Lumix GH5S Camera - Review of a device with a smarter approach to pixels

Panasonic Lumix GH5S is the new flagship camera for professional videographers. It features a new 10.2 MP digital Live MOS sensor, Venus Engine and Dual Native ISO technology, which together make it the most capable low-resolution camera available.

What's special about the Panasonic Lumix GH5S?

The new Panasonic Lumix GH5S is the world's first mirrorless camera to offer 4K (4096x2160) video recording and is capable of shooting Full 1080 HD slow-motion video at 240 FPS.

This camera is equipped with additional technologies to provide impressive performance in low light conditions.

Familiar design

The Panasonic Lumix GH5S is almost identical to the GH5 in design, except for the bright red "REC" button on top. The camera feels light, this is due to the removal of the image stabilization system. The equipment can also be charged via USB, allowing you to easily connect an external battery for longer operation.

The GH5S has the same 3.68 million. electronic viewfinder, the same 1.26 mm LCD monitor and the rugged body we are already familiar with. It's not the most beautiful DSLR camera I've seen, but it is very functional.

These are the pixels you were looking for

The first and most noticeable feature of the Panasonic Lumix GH5S is its 10.2 MP multi-sensor. The advantage of the GH5S over the GH5, as well as other cameras with higher pixel density, is that each pixel on the chip is larger, which increases its sensitivity to light and improves low-light performance.

In fact, the GH5S has a new maximum ISO of 51200, which is two stops higher than the GH5. This isn't as important for photographers, who can tweak their shots to remove high-ISO noise, but videographers don't have the same editing flexibility. This camera records exactly as many pixels as needed: one pixel for each, which is processed and output in the last frame.

While 1:1 sampling is certainly better than skipping or binning, oversampling will technically produce sharper results. However, due to existing limitations of sensor and processor technology, the updated camera is similar to the GH5, it must read pixels one line at a time.

The more pixels are recorded, the longer this process takes, causing a "jelly" effect. This is especially true when shooting fast moving objects. But thanks to its low-resolution sensor, the Lumix GH5S will produce photos with the least jello effect, have lower light output, and support clear video with 1:1 sampling.

Image quality

The Panasonic Lumix GH5S uses the same internal 4:2:2 10-bit, 400 megabits per second codec as the Lumix GH5, which is still a powerhouse in a small camera environment. But Panasonic has found ways to improve this.

Panasonic here for the first time introduced dual ISO technology in the Lumix series cameras, borrowed from the professional Varicam line. Two capacitors are assigned to each pixel, one of which is set to the other ISO. This gives the Lumix GH5S two different ISO settings (400 and 2500) that have the same performance.

The GH5S gets 14 stops of dynamic range for RAW still photos, unfortunately none for video, likely due to the lack of a RAW video format.

The upside of dual ISO is that videographers will have more flexibility when working in different lighting conditions, without having to use artificial lighting or neutral density filters for better ISO settings.

While the GH5 shoots 4K Ultra HD video (3840x2160 at 60 fps), the updated GH5S offers DCI 4K (4096x2160 at 60 fps) - a world first. This means that users will now be able to shoot slow motion videos in a wider aspect ratio without changing the resolution. And 1080p can now be shot at 240 fps, up from 180 fps on the GH5.

New Video Features

Improved video quality is always welcome, but quality isn't the only thing professional videographers need. The Panasonic Lumix GH5S is packed with features that make this camera more useful and more versatile than its predecessor.

The V-LogL add-on for the GH5, which costs $100 (RUB 5,500), comes standard on the Lumix GH5S, as does Hybrid Log Gamma (HLG). V-LogL is an implementation from Panasonic that greatly enhances the post-processing capabilities of captured video.

The GH5S also features a LUT display function that allows you to view the actual state of the frame directly in the camera. This was previously only possible using a professional external monitor.

The monitor isn't the only thing the Lumix GH5S copied from the GH5. To evaluate exposure and color vector, the equipment has a separate screen area with an oscilloscope. Having these tools right in the camera will allow you to create more accurate shots.

The new Panasonic Lumix GH5S also features a flash sync port (BNC cable included), allowing it to sync with other camcorders. This is especially useful for multi-camera productions where synchronization from different angles is important.

Why won't all videographers want the GH5S?

The Lumix GH5S will be fine for most users, but one area where it still falls short is Anamorphic 4:3. It still has that ability, but due to its fewer pixels, it's limited to 4K resolution.

While the previous Lumix GH5 is capable of recording 6,000 anamorphic frames, which is impressive especially for a $2,000 mirrorless camera, with better performance and less noise, the GH5S is a better choice.

For regular users, the main drawback of the Panasonic Lumix GH5S will be the lack of image stabilization, while the GH5 has a fantastic 5-axis image stabilizer. For professionals, this will not matter so much, because they use reliable tripods.

Panasonic Lumix GH5S in photography

Apart from the resolution, the Lumix GH5S borrows most of the useful features from its older brother. These include depth detection and the Defocus autofocus system, which is now even more sensitive, down to -5EV, making it easier to shoot in dark conditions.

The continuous shooting speed remains 12 fps with autofocus, or 8 fps with continuous autofocus, and the body is still protected from dust, moisture and cold. All this allows you to use the Panasonic GH5S camera almost anywhere.

Panasonic Lumix GH5S is a very interesting mirrorless camera for a certain circle of people. This is a professional video tool that can shoot both amateur films and Hollywood blockbusters.

However, the standard GH5 remains the best choice for most users. The sensor is higher resolution, and built-in image stabilization makes the camera more versatile and accessible than the hyper-focused GH5S.

But if you're primarily a videographer who shoots a lot in good light, the Lumix GH5S could be your best camera, and trust me, it does the job just as well as its more expensive competitors.

Advantages of Panasonic Lumix GH5S

Dual ISO with obvious advantages.
10.2 MP interface with multi-sensor.
Impressive low light photography.
Good battery life.
Protected and small body.
Compatible with GH accessories
Video recording up to 240 frames per second.
Unlimited CINE 4K video recording.
Built-in Bluetooth connectivity.

Disadvantages of Lumix GH5S

No image stabilization.
There is no built-in IBIS.
More expensive than GH

From the outside, the Panasonic Lumix GH5S is similar to the GH5, except for the bright red "REC" button on top. Due to the lack of a 5-axis stabilization system, this camera is slightly lighter than its predecessor. But the difference in weight is small - equivalent to the mass of the battery.

Additionally, the Lumix GH5S has the same 3.68-mil, 1.62-mil electronic viewfinder. articulated touch LCD display and the same durable body as its brother in the series. It's not the prettiest DSLR camera out there, nor is it as refined as the Lumix G9, but it's very capable.

But some of the GH5S's controls feel and look cheap for a $2,500 camera, and the joystick isn't as responsive as I'd like. Additionally, connecting headphones (or HDMI/USB cables) interferes with the screen's rotation.

2. Only the necessary sensor pixels

The Panasonic Lumix GH5S has a 10.2MP sensor, which is about half the number of the standard GH5. It's a little strange, as if Panasonic is asking customers to pay more for less, but it's actually good for video recording.

By packing fewer pixels into the sensor, sensitivity to light is increased, which improves low-light performance. The Lumix GH5S has a maximum ISO of 51,200, which is two stops more than the GH5.

On the Panasonic GH5S, photographers will be able to downsample 20MP to 10MP to reduce ISO noise, but videographers won't have the same flexibility. This is why working with fewer pixels is better for video shooting. But low light is not the only advantage of this camera's low resolution when it comes to video.

4K video shot on the GH5S has enough resolution for most applications, however, it only measures 3840x2160 or about 8.3 MP, which is underwhelming. The Panasonic Lumix GH5S camcorder sensor is specifically designed to produce DCI 4K (4096x2160) with the required number of pixels, where one more pixel is recorded for each pixel, which is processed and output in the last frame.

As such, the Lumix GH5S produces the least jello effect, has lower light output, and supports crisp video at 1:1 sampling thanks to its lower resolution sensor. Panasonic's new camera sensor also uses an oversized multi-aspect ratio design, maximizing the field of view whether you choose 3:2, 4:3, 16:9 (Ultra HD) or 17:9 (DCI 4K).

3. New tools for video professionals

The sensor is not the only update in the Panasonic Lumix GH5S. The camera is packed with features that make it more useful and versatile than the GH5.

V-Log L, a $100 add-on for the GH5, is now standard on the GH5S. With V-Log L, users gain more flexibility in the shooting process and increased dynamic range in post-processing. The Lumix GH5S also has a LUT function that allows you to view your finished footage directly on the camera.

Panasonic's GH5S also has a built-in waveform for assessing exposure and color vector. Having these tools allows you to create more accurate footage without the need to connect to an external monitor.

Availability of time code input/output via the flash sync port (BNC adapter video cable included) on the Lumix GH5S allows synchronization with other professional camcorders. This is especially useful for recording live scenes, filming music videos or interviews with two cameras.

4. Video like a Hollywood movie

The new Panasonic Lumix GH5S offers the best video quality of any camera I've reviewed. Despite the 10.2 MP sensor, it creates beautiful video in different lighting conditions.

I shot video with a high quality 4:2:2 10-bit codec at 400 megabits per second. The shots turn out incredible. However, such a powerful codec requires a lot of computing power.

You'll also need a large, fast memory card. Ten minutes of video at 400 Mbps is about 32 GB in size. I tested the Panasonic GH5S with ProGrade Digital's V60 card and didn't notice any problems.

Panasonic pioneered dual ISO with the Lumix GH5S. As a company representative explained, this creates two additional pixels behind each pixel, each set to a different ISO range. This gives two different ISO settings, providing better dynamic range at low ISO while reducing noise at high ISO.

This offers videographers more flexibility when working in different lighting conditions without having to rely on artificial light sources or neutral density filters. The GH5S can also automatically boost ISO smoothly for more natural transitions from inside to outside.

When shooting in V-Log L, noise is present throughout the ISO range, but it is well controlled and can be minimized using additional dynamic range.

Unlike the GH5, the GH5S offers higher frame rates. While the previous model offered Ultra HD 4K (3840x2160) at 60 fps, the Lumix GH5S offers DCI 4K (4096x2160) at the same fps, which allows you to shoot slow-motion video without reducing resolution.

Why do some people not like the Lumix GH5S?

There's one area where even high-end photographers will prefer the GH5 - 4:3 anamorphic shooting. The Panasonic Lumix GH5S also has this ability, but due to its fewer pixels, it's limited to 4K resolution. The Panasonic GH5 can record 6,000 anamorphic frames, which is especially impressive for a $2,000 mirrorless camera. However, if you want better noise performance and less jello, the GH5S is a better choice.

The main drawback of the Lumix GH5S is the lack of image stabilization. This isn't a big deal for studios and larger productions where cameras are stabilized by a reliable gimbal, but for mobile operators it can be the most important factor.

5. Photo quality

If you don't like the Panasonic Lumix GH5S, you can buy the Lumix G9. However, the GH5S has one potential advantage over the GH5 and G9: 14-bit RAW files.

The lack of stabilization on the Lumix GH5S means you'll have to resort to higher ISO settings to prevent blur and reduce noise.

Besides resolution and stabilization, the GH5S has more of the great features from the GH5. The viewfinder refreshes at 120fps, and Defocus AF tuning has a sensitivity of -5EV.

Given the low resolution, I expected a higher continuous shooting speed. The flash speed is 12 frames per second with automatic, and 8 frames with continuous autofocus. I also didn't notice any slowdown when shooting at the smaller apertures that I experienced with the G9.

Is there a better alternative to the Panasonic Lumix GH5S?

For the target audience - no. The device produces the most amazing video I've seen at this price point and gives users more power, more control, than competing models. Panasonic Lumix GH5S is one of the best video cameras under $3,000 (RUR 185,000).

Most other users will prefer the standard Lumix GH5 or any other high-quality DSLR camera.

Is this camera worth buying? You decide.

The Panasonic Lumix GH5S is a product aimed at a small group of users and its advantages will not be obvious to everyone, due to a couple of disadvantages like the high price, lower resolution photos and lack of image stabilization.

The new Lumix GH5S is a very interesting camera, but for a certain circle of people. While it looks like a hybrid DSLR camera, it's professional production equipment that can be used for everything from student films to Hollywood blockbusters.

If you don't mind some of the shortcomings, the GH5S is the best option today.

Panasonic LUMIX GH5S is the company's best digital camera

The Japanese company Panasonic has announced a new hybrid digital mirrorless camera LUMIX GH5S, which has extensive video capabilities and improved image quality. As the company notes, its new product is designed for film and video production professionals, and provides high light sensitivity and the best image quality in the entire history of the LUMIX family of cameras.

The presented device is equipped with a new 10.2 MP Digital Live MOS sensor with Dual Native ISO technology and the Venus Engine image processor, allowing for light sensitivity up to ISO 51200, which is especially important when shooting in low light conditions. And when shooting video, noise in the image is effectively suppressed by the new Dual Native ISO technology.

Like professional camcorders, the LUMIX GH5S supports timecode synchronization via the Time Code IN/OUT connector and the supplied coaxial cable. The LUMIX GH5S can also be used as a timecode generator for other GH5S cameras and professional camcorders. Timecode synchronization makes the crew's work easier by synchronizing video and audio with another camera or audio recording device, making multi-camera shooting much easier.

The new sensor also allows for different aspect ratios (4:3, 17:9, 16:9 and 3:2) while maintaining the viewing angle. The camera also supports photography in 14-bit RAW format, which opens up great possibilities for professional processing.

The previous model, LUMIX GH5, was the first among digital mirrorless cameras to support video recording in 4K 60p / 50p format. And the new LUMIX GH5S is the first camera to support Cinema 4K resolution (4096x2160). The GH5S can also record in 4:2:2 10-bit format, which is often used in film production, allowing for more accurate color reproduction. There is also support for 4:2:2 10 bit 400 Mbps All-Intra formats in 4K 30p/25p/24p resolution and C4K 24p and 200 Mbps All-Intra in Full HD resolution, while there is no limitation on the duration of video recording as with Full HD and 4K. In addition, LUMIX GH5S is compatible with 4K HDR video in Hybrid Log Gamma (HLG) mode. Support for 4K HEVC video recording is also available, allowing video playback on compatible equipment.

Other features of Panasonic LUMIX GH5:

Video shooting in C4K/4K resolution at up to 60 frames per second and in Full HD at up to 240 frames per second;
