The Panasonic GH4R continues the success of the GH4 with the addition of unlimited 4K recording and V-Log L video capability to meet the high demand from the film production industry. Compact and lightweight, the GH4R retains all of the specifications found in its predecessor, making it the ideal tool for photographers and videographers who want to capture beautiful 16.05 megapixel imagery and smooth 4K video on the move. The Digital Live MOS sensor with DFD (Depth from Defocus) technology combined with the speed of the Venus Engine ensures lightning fast AF (approx. 0.07 sec) and 12 fps burst shooting, along with higher sensitivity (max. ISO 25,600), better gradation performance, resolution and colour reproduction to achieve even higher image quality. The GH4R also boasts an OLED 2,359K-dot electronic viewfinder, a 3.0″ 1,036K-dot rear monitor with 100% coverage and Wi-Fi with NFC technology.

Panasonic Press Release:
The photo/video hybrid now offers unlimited(1) 4K recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps in MOV/MP4*) and V-Log L video capability, in addition to the high performance and functionality synonymous with Panasonic’s range of LUMIX G CSC cameras.
V-Log is also available to existing LUMIX DMC-GH4 users, via a paid software upgrade. By purchasing the DMW-SFU1 Upgrade Software Key and updating the camera’s firmware to version 2.3, users of the original LUMIX DMC-GH4 can also enjoy the benefits of V-Log L functionality for a one off cost.
With the updates to the LUMIX DMC-GH4, Panasonic has created a camera that’s perfectly suited to both professional and amateur videographers alike. Panasonic’s 4K technology allows all users to capture immersive video like never before, while unlimited Log recording allows greater flexibility and accuracy for professional videographers.
In addition to exceptional flexibility, Log shooting also enables wider dynamic range for colour grading in post-production. Taking full advantage of the LUMIX DMC-GH4R’s Four Thirds sensor, V-Log L boasts log characteristics with 12 stops, allowing videographers to capture the darkest scenes and avoid ‘bleaching out’ details in very bright environments.
The LUMIX DMC-GH4R is the ideal camera to support Panasonic Varicams used on TV and movie sets. This is due to the Varicam’s V-Log and the LUMIX DMC-GH4R V-Log L curve both being developed with similar characteristics to the Cineon curve, the industry standard for film digitalisation, resulting in being able to use the same LUT (Look Up Table) for reference.
The clean HDMI output from the GH4R provides a higher quality 4:2:2 10bit output with over 984 million more colour graduation, making it the perfect partner for the Atomos 4K Shogun and Ninja Assassin. In addition, when shooting in V-Log L you can utilise the 3D LUT capability of the Atomos 4K recorders to monitor your content in REC709 – or your choice of old film stock or own signature looks.
Compact, rugged and lightweight, the LUMIX DMC-GH4R retains all of the LUMIX DMC-GH4’s specifications, making it the ideal tool for photographers and videographers who want to capture stunning imagery on the move.
Beautiful stills with minimal noise
The LUMIX DMC-GH4’s newly-developed 16.05-megapixel Live MOS sensor achieves high quality results every time, with the high sensitivity image recording and lightning fast response times that professionals expect. The high power Venus Engine image processor allows the camera to produce fantastic results with minimal noise – whether you’re reportage shooting in a crowded street or capturing shy wildlife at dusk.
Durable, lightweight and ready for adventure
You have to be agile to get the perfect shot in the field – so the LUMIX DMC-GH4’s lightweight and compact design means you’ll be able to seamlessly move through crowds or through challenging environments with ease. To be tough enough to withstand even heavy field use, the main structure of the DMC-GH4 is composed of magnesium alloy full diecast front / rear frame. It also features splash / dustproof construction thanks to the sealing on every joint, dial, and button. The shutter unit is also redesigned to be even more durable for approx. 200,000 times release
2,359K-dot Electronic Viewfinder
The DMC-GH4 boasts newly developed high-precision, high-speed dual OLED (Organic Light-Emitting Diode) displays for LVF (Live View Finder) and rear monitor. Increasing the resolution of display area to 2,359K-dot, the new 16:9 Wide Screen LVF boasts approx.1.34x / 0.67x (35mm camera equiv.) magnification and 100% field of view and eyepoint of approximately 21 mm. Thanks to the newly designed large eyecup, the visibility of LVF is dramatically improved. The image output between the LVF and the rear monitor is switched automatically with the eye sensor on the LVF, which features options of sensitivity – high, low and off – to reduce false operation during touching on the rear monitor.
3.0″ 1,036K-dot free-angle OLED rear LCD
The 3.0-inch 1,036K-dot free-angle OLED rear monitor (3:2 aspect) with wide-viewing angle rotates 180° to the side and tilts 270° up and down offers approx. 100% of field of view. This rear monitor adopts static touch control for more smooth operation either in shooting or in playback. Both LVF and rear monitor adopts OLED to achieve high speed response with minimum time lag while enhancing the resolution. Notably, the OLED for the LVF in DMC-GH4 boasts 10,000:1 high contrast for superior color reproduction. Now the excellent visibility comes closer to OVF. On the other hand, live view image can be displayed in monochrome through LVF which enables shooting concentrating on contrast.
High speed, high precision shooting
The Contrast AF system in the DMC-GH4 is further enhanced by Panasonic’s integration of DFD (Depth from Defocus) technology which even shortens the time to set focus. It figures out the distance to the subject by evaluating 2 images with different depth of field while consulting the data of optical characteristics of the using lens in a moment. As a result, the DMC-GH4 achieves ultra high speed AF of approx.0.07 sec*3. This improvement benefits more as focusing distance increases. The speed of burst shooting is dramatically faster than the predecessor DMC-GH3, boasting high speed burst shooting at 12 fps (AFS) up to approx.40 (including RAW) / approx.100 (excluding RAW) and 7.0 fps (AFC) to capture fast moving subject just in-focus.
