Update: According to Panasonic UK, the Lumix DMC-GH4R will only be offered in Europe and will be priced at £1199.


Panasonic has announced the Lumix DMC-GH4R, a variant of the GH4 that offers a Log gamma curve and unlimited 4K video recording. There will also be a paid-for firmware update adding the V-Log L Photo Style to the GH4 - a super-flat tone curve designed to capture the maximum dynamic range for greater flexibility while color grading.

The V-Log L curve has been designed to have similar characteristics to the industry standard 'Cineon' curve, so that the same look up tables (LUTs) can be used to easily transform the color response across to other profiles and styles. Panasonic highlights the camera's ability to output a 10-bit uncompressed signal with 4:2:2 chroma sub-sampling, which should result in very flexible, gradable files when V-Log L footage is recorded by an off-board capture device, such as the Atomos Shogun.

In addition, the GH4R is no longer limited by the 29:59 minute cap on video recording, meaning that the camera can continue to shoot DCI 4K (4096 x 2160) at 24p or UHD 4K (3840 x 2160) at up to 30p for as long as necessary. This change won't be part of firmware v2.3 for GH4 owners, perhaps because it would be difficult to recover and pay the additional duty owed on the de-limited cameras (since they would class as video cameras, which attract a higher rate of duty).

Panasonic will charge $99/€99/£79 for the upgrade.

US customers can buy and download the firmware from the Panasonic website, which also has details of the process required to authenticate the update.

The Panasonic LUMIX DMC-GH4R: The ultimate photo/video hybrid just got better

With updated V-Log L Compatibility, the LUMIX DMC-GH4 continues to push the boundaries of photography and videography

1st September 2015 – At IFA 2015, Panasonic is showcasing the LUMIX DMC-GH4R, an advanced version of the LUMIX DMC-GH4, as well as a comprehensive software update for existing users.

Following the critically acclaimed launch of the LUMIX DMC-GH4, the LUMIX DMC-GH4R comes in response to growing demand from the film production industry. The photo/video hybrid now offers unlimited1 4K recording (Cinema 4K: 4096x2160 / 24 fps and QFHD 4K: 3840x2160 / 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. The GH4R will be available from 7th September 2015 and will RRP at £1199.

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 of £79.

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.
