Panasonic has the widest range of 4K cameras in the market, and has expanded the 4K video recording capabilities of the GH5 (in comparison to the GH4R), as well as introducing a 6K photo mode, that can record 6K video at 30fps, for 18 megapixel still photos.
The GH5 offers 12fps continuous shooting, 9fps with continuous AF, improved AF speeds, updated DFD (Depth-from Defocus) technology for quicker focus with improved motion detection (and prediction), as well as an improved ISO range from ISO100 (low) to ISO25600 for stills, and ISO100 to ISO12800 available for video.
The shutter of the camera has been improved, to make it quieter, and features less vibration compared to the GH4, (reduced to 1/6th of the GH4) and it is rated for 200,000 shots. The shutter unit now features a floating construction with mechanical shutter speeds up to 1/8000s. Electronic shutter speeds can be used up to 1/16000s.
The AF system can now be customised based on your intended use, with 4 custom AF modes available, and 225 focus points. The menu system has been updated to be clearer to use, and adds a customisable My Menu section.
The 20-megapixel sensor has no optical low-pass filter, and is designed to give improved levels of detail (leaves etc) compared to the 16mp GH4, and 20mp GX8, with better edge detail. It's said that improved image processing has meant that edges are sharper and detail improved, whilst not being over sharpened. Colour is also said to be improved with a new 3D colour control system.
Image Stabilisation (IS) - "Dual I.S. 2" is said to give up to 5 stops of IS, with the in-body sensor based 5-axis image stabilisation working in combination with any lens with optical image stabilisation.
6K Photo - With a new 6K photo feature, you can now record 18-megapixel photos (5184x3888) at 30fps, with an unlimited recording time, and the camera has the same burst options as other Panasonic cameras with 4K photo, including Burst, Burst (Start/Stop), and Pre-Burst. 4K Photo has been updated to shoot at 60fps, and both 6K and 4K photo modes can now benefit from auto noise reduction, as well as rolling shutter distortion correction.
Video features – All video modes benefit from the new 5-axis sensor based image stabilisation. Video specifications have been massively upgraded so that the camera is suitable for professional use, with the camera recording CINE 4K at 24fps, 4K video at 60fps, 4K 4:2:2 10bit at 30fps, and FullHD video up to 180fps. Video recording time is unlimited, and the camera uses the full-sensor, compared to the GH4 which used a cropped area of the sensor. The camera body also features a full-size HDMI connection, and comes with a HDMI cable lock in the box. Nb. See below for a more detailed list of video features (of which there is an almost never ending list).
* The camera will also receive firmware updates to support the recording of 4K HDR (High Dynamic Range) video, with a firmware roadmap (below) showing further video improvements that will be released in April and Summer 2017. From release, the camera can record 4K at 150mbps, which will be upgraded to ALL-Intra 400Mbps with the Summer 2017 firmware.
Firmware update schedule:
April 2017: FHD 4:2:2 10bit (NAB)
Summer 2017: 4K 2:2:2 10bit ALL-Intra, FHD 4:2:2 10bit ALL-Intra,
Summer 2017: High-resolution Anamorphic Video Mode, Hybrid Log Gamma for 4K HDR Video (for use with 4K HDR TVs)
Physically, the GH5 offers a larger 3.2inch vari-angle touch-screen with a high resolution of 1.62m dots (RGBW, Whitemagic display), and a new 3.68million dot Electronic Viewfinder (EVF), with 0.76x magnification. The GH5 has a weather-sealed magnesium alloy body that is splash, dust and freeze proof. The camera also supports Dual SD (UHS-II) card slots.
Wi-Fi, and Bluetooth are built-in. The full-time Bluetooth connection is available for auto transfer of images, plus easy remote control, and the ability to copy settings from one camera to another, which will help when setting up a number of cameras.

The Panasonic Lumix GH5 has a subtly updated design, with a larger screen, and higher resolution electronic viewfinder (EVF), which looks great. There’s also a new function button on the front of the camera, and a joystick on the back. The camera does not feature a built-in pop-up flash, unlike the GH4/R, and the camera is larger and heavier than the GH4/R.
Build quality is excellent, with a tough magnesium alloy body that is weather sealed. The top buttons are cleverly designed, with the WB button raised, the ISO button has two raised dots, and the exposure compensation button is lower. The video button is also larger than on the GH4/R, and this has been moved to the top of the camera. The handgrip has been improved, giving excellent grip, and it is quite large.
There’s an improved menu system – with less pages to scroll through (as they’ve fit more on one page), clearer colour coding for each section, (see video), and when options are greyed out, the camera will tell you why. There is a My Menu section where you can put up to 23 of your most commonly used settings. The autofocus system has been updated, and there are now a range of different AF scenarios, with settings for AF sensitivity, AF area switching sensitivity and moving object prediction.
There are numerous customisable function buttons on the camera, 6 physical buttons in total, far more than most cameras provide. This gives you good control over customisation, so you can set up the camera as you'd like it. 5 are available using the touch-screen. You can also customise the 4-way controller and the joystick on the back, giving you another 9!
The layout of controls and buttons is well thought out, with the front top and rear command dials falling neatly to hand. You can also reach the majority of controls and buttons on the back with your right hand thumb. There are just a few controls on the left hand side of the camera, including the drive mode dial on top, and the playback and LVF (Live ViewFinder / Electronic ViewFinder) buttons.
The electronic viewfinder offers an impressively high resolution at 3.68million dots (only the Leica SL is higher at 4.4m), and offers 0.76x magnification (an improvement over the 0.67x of the GH4/R) – you can’t really tell that you’re looking at an electronic display when using it, apart from the overlay of graphics. The eyecup surround is large, and eye-detection means the camera automatically switches between the EVF and screen.
The touch-screen on the back is now 3.2inch (1.6m dots) and catches up with other premium ILC cameras (such as the Canon EOS 5D Mark IV). The screen and EVF colour reproduction match each other, which is what you expect from a camera at this price point. The rear screen can be viewed in bright sunlight, and the ability to alter the angle and position also helps here.
There are 225 focus points, and the camera can focus down to -4EV. You can use the touch-screen to set the focus position, and this can be set to anywhere on the screen, even into the far corners.
Battery life - The camera has a battery life of 410 shots, which can be extended to 1000 shots using the "Power Save LVF mode". This can be doubled, with the use of the optional weather-sealed battery grip.
