Panasonic Press Release:

The photo/video hybrid now offers unlimited(1) 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.

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.

Creativity and expandability
The LUMIX DMC-GH4 also features a variety of settings and modes that will help you further unleash your creativity, even before the post-production process. With VFR (Variable Frame Rate), video can be recorded in both dramatic slow motion and thrilling fast motion - from 2 fps to 96 fps or 4x speed - all in Full HD. You can create the next viral internet hit with stunning stop motion animation and time lapse shots, while precise control over video image quality can be achieved through advanced settings such Zebra Pattern, which allows you to finely control white wash-out.

Wi-Fi with NFC connectivity
The DMC-GH4 integrates Wi-Fi connectivity (IEEE 802.11 b/g/n) with NFC (Near Field Communication) technology camera to offer more flexible shooting experience and instant image sharing with easy operation. With Panasonic "Image App", remote shooting of both photo and video is available by using the smartphone/tablet for a remote shutter with a monitor. Not only releasing a shutter, zooming, focusing and settings of shutter speed, aperture, exposure compensation are all controllable with a smartphone / tablet. All these flexible shooting / browsing / sharing style are made possible with the DMC-GH4 and the Panasonic's dedicated application software Panasonic Image App for iOS / Android smartphones / tablets. It is also easy to embed geotag in the image after shooting. For the smartphone/tablet without NFC, the camera displays dedicated QR code on its monitor to complete pairing easily by reading the code.

Output/Input Terminals
The DMC-GH4 comes with a variety of connection terminals for more flexible shooting options. The 3.5mm microphone jack is for high quality audio recording using an external microphone and the 3.5mm headphone jack which enables monitoring the recording audio while shooting video real-time. It is also capable of real-time image output on the external monitor via an optional HDMI micro cable simultaneously while recording video. In addition to these, the DMC-GH4 complies with AV outputs (Audio 2ch, Composite), flash sync terminal and 2.5mm jack for remote controller.
For reliable recording of rich video, the DMC-GH4 complies with UHS Speed Class 3 (U3) which is the new speed class standard of SD memory card. The UHS Speed Class 3 (U3) guarantees a constant minimum write speed of 30MB/s to respond to market needs for 4K video.

Time Lapse Shot / Stop Motion Animation
Time Lapse Shot and Stop Motion Animation are available for stationary observation for subjects or for producing a stop motion (stop frame) video with sequential pictures. Both can be produced in camera without needing postproduction process.

Luminance Level Adjustment
Just as the concept of "ultimate hybrid Digital Single Lens Mirrorless camera" identifies, the DMC-GH4 supports smooth postproduction for photographers newly challenging videography. In addition to the standard luminance level of 16-235* and 16-255*, DMC-GH4 offers 0-255* which is equivalent to photo standard. *8-bit

Focus Peaking
For more practical control over focusing, the DMC-GH4 incorporates Focus Peaking function that shows the peak of focus in MF and AF+MF mode. Users can see the peaking of focus while monitoring the subject in live view. It can be set to HIGH / LOW / OFF and the color can also be changed to blue, white or orange according to the color of the shooting scene during live view. Users can take advantage of this function when controlling the camera with smartphone / tablet via Wi-Fi in both photo / video recording.

Silent Mode
This mode switches shutter from mechanical to electronic and turns all sound (AF, operation) off while suppress emission of AF assist lamp and flash with just a single setting for special shooting occasions.

Highlight/Shadow Control
The Live View function is also advanced digitally making it possible to adjust highlight / shadow separately with the front/rear dial. 3 patterns of settings can be customized in addition to 3 patterns of preset.

RAW data development in Camera
The DMC-GH4 is capable of developing RAW image in camera. In addition to the color space setting ( sRGB / AdobeRGB ), the parameter of white balance, exposure compensation, contrast, highlight/shadow, saturation, noise reduction, sharpness or hue can be flexibly adjusted while LUMIX’s Photo Style, Intelligent D-range Control, Intelligent Resolution can also be applied.
