LUMIX G Camera DMC-GH4
Photos to impress, 4K videos to inspire
The GH4’s new Live MOS Sensor and Venus Engine team up to reduce noise while raising resolution and improving color reproduction. Innovative DFD technology increases the speed of Contrast AF. As the world’s first* DSLM camera to record 4K videos, it truly meets the needs of professionals.
Superb Picture Quality for Lifelike Textures
The image processor Venus Engine is newly developed with new quad-core CPU that enables high speed signal processing. Combination of new Digital Live MOS Sensor and the Venus Engine dramatically improves sensitivity (max.ISO25600), gradation performance, resolution and color reproduction to achieve even higher picture quality. Yet its image description is natural – that is what LUMIX aspires for.
Capturing High-resolution Photos from 4K Video
Cut out magical moments in 8-megapixel equivalent resolution from 4K video footage. Once selecting the 4K Photo Mode*, recording format / picture quality setting / brightness level are automatically set to the optimum parameter for photo shooting. You can also choose either 4:3 or 3:2 in addition to 16:9. Each JPEG image cropped out of the video footage complies with EXIF information. Marking function and Loop Rec function are also available.
Video Shooting Performance
World’s First*1 4K Video Recording
One of the most prominent features of GH4 is unlimited*2 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) in MOV/MP4*3.

*2 Motion image can be recorded up to 29 min 59 sec depending on the recording format and the camera’s sales area.
*3 Use SDXC/SDHC Memory Card compatible with UHS Speed Class 3 (U3) when using high bitrate video recording mode over 100 Mbps.
Mobility & Response
Contrast AF with DFD Technology
The Contrast AF system is advanced with the DFD (Depth From Defocus) technology which even shortens the time to focus. It calculates the< distance to the subject by evaluating 2 images with different sharpness level while consulting the data of optical characteristics of the current lens in a moment. As a result, ultra high speed AF of approx.0.07 sec* is achieved. This improvement benefits more as focal length increases.

Design & Control
Magnesium Alloy Body & Rugged Design
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.
High Performance Shutter Unit
The shutter unit is also redesigned to be even more durable for approx. 200,000 times release. It offers highest shutter speed at max. 1/8000 not only to capture spur-of-the-moment for fast moving subject but also to use high-speed lens with open aperture even in outdoors to give impressive defocus. Both built-in / external flash can be synchronized with max.1/250 second shutter speed.
Optimum Layout of Control Components
For quick, intuitive control, 3 dials are equipped on the top and back of the camera and the main dial is now comes with lock structure. A dedicated button allows direct reach to exposure compensation, white balance adjustment or ISO setting and max.5 settings can be assigned to the Fn button. All these external components are designed to be operated easily without taking eyes off from the viewfinder.
Terminals for Expanded Connectivity
The DMC-GH4 comes with a variety of connection terminals. The 3.5mm microphone and the 3.5mm headphone jacks. 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, AV outputs, flash sync terminal and 2.5mm jack for remote controller are available. It complies with the SDXC / SDHC Memory Card UHS Speed Class 3 (U3).
Wi-Fi® with NFC Technologyt
The DMC-GH4 integrates Wi-Fi® connectivity (IEEE 802.11 b/g/n) with NFC (Near Field Communication) technology. With the “Panasonic Image App”, remote shooting of photo / video is available with smartphone / tablet. 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.
New Interface Unit
The Interface Unit(DMW-YAGH) is offered exclusively for professional / industrial workflow enabling more powerful video transmission. It complies with Full HD (4:2:2 / 10 bit) four parallel output or 4K (4:2:2 / 10bit) output, both with time code*. The 2ch XLR input terminals are also equipped for line or condenser microphone. Microphone volume can be controlled L / R separately. It compies with 12V DC IN.
* When using 4:2:2/10-bit output, simultaneous video recording on SDXC/SDHC Memory Card in the
