MISSISSAUGA, ON (February 7, 2014) – Panasonic Canada Inc. is proud to introduce the ultimate photo / video hybrid Digital Single Lens Mirrorless (DSLM) camera, the DMC-GH4. The successor to the award-winning DMC-GH3, the newly-launched GH4 is the world’s first DSLM camera with 4K video recording capability.

The newly developed 16.05-megapixel Digital Live MOS Sensor for DMC-GH4 excels in both sensitivity and response, and suppresses rolling shutter effect even when using the electronic shutter or recording video. The image processor, Venus Engine, is also newly developed, dramatically boosting its performance with new quad-core CPU that allows high speed signal processing for the rich video recording required by 4K technology. Integrating superior noise reduction systems, the DMC-GH4 enables shooting at max. ISO25600. Sensitivity, gradation performance, resolution and colour reproduction are dramatically improved to achieve even higher picture quality.


The DMC-GH4 also boasts high speed burst shooting at 12 fps (AFS) up to approximately 40 (including RAW) / approximately 100 (excluding RAW) and 7.0 fps (AFC) to capture fast moving subjects.

The new DMC-GH4 further evolves to bridge the gap between consumer and professional video cameras. One of the most prominent advances is unlimited*1 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) in MOV/MP4*2. The DMC-GH4 is also capable of recording full-HD video with ultra high bitrate at 200 Mbps (ALL-Intra) or 100 Mbps (IPB) without recording duration limit*1*2. Users can freely choose the format from MOV, MP4 (LPCM), AVCHD Progressive and AVCHD at a variety of frame rates according to the usage. For global business of professional users, the system frequency can be selected between 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz. The DMC-GH4 is also capable of real-time image output to the external monitor via an optional micro HDMI cable simultaneously while recording video. For more unique video expression, VFR (Variable Frame Rate) or Time Lapse / Stop Motion Animation can be produced without postproduction.

The high-precision Contrast AF system in the DMC-GH4 is further enhanced by Panasonic’s integration of DFD (Depth from Defocus) technology which shortens the time needed to set the focus to achieve the ultra-high speed AF of approximately 0.07 sec*3. In addition to speed, operability is enhanced thanks to the addition of Face / Eye Detection AF or 49-point AF with Custom Multi AF mode.

The DMC-GH4 features newly developed high-precision, high-speed dual OLED (Organic Light-Emitting Diode) displays for 2,359K-dot LVF (Live View Finder) and 1,036K-dot rear monitor. Both LVF and rear monitor adopt OLED to achieve high-speed response with minimum time lag while enhancing the resolution. Notably, the OLED for the LVF boasts 10,000:1 high contrast for superior colour reproduction, with the clarity more closely resembling an optical viewfinder.

Tough enough to withstand even heavy field use, the main structure of the DMC-GH4 is composed of a magnesium alloy full diecast front / rear frame. It also features splash / dustproof construction thanks to the sealing on all joints, dials and buttons. The shutter unit, that allows maximum 1/8000 fast shutter release, is also redesigned to be even more durable for approximately 200,000 shutter actuations*4.

Every moment counts in professional shooting conditions, and thanks to the optimum layout of control devices on the DMC-GH4, it is possible to make target setting intuitive. The DMC-GH4 also incorporates Wi-Fi® with NFC technology and a variety of terminals making it highly connectable to external equipment. The GH4 is also capable of developing RAW files in camera with parameter adjustments.

Concurrent with the announcement of the GH4 camera, Panasonic also announces the introduction of the new Gold Series SDUC memory cards, including SDXC and SDHC UHS-I type versions. The new cards comply with UHS Speed Class 3, suitable for 4K video recording, and are capable of stable and continuous real-time video recording at a minimum write speed of 30 MB/s (240 Mbps). In addition to unlimited 4K video recording in MOV/MP4 format, the Gold Series SDUC cards are also capable of ultra-high bitrate video recording at 200 Mbps (ALL-Intra) or 100 Mbps (IPB) for smooth, high-quality video without the dropouts caused by an insufficient write speed.

Evolving further in every aspect – performance, mobility, durability and expandability, Panasonic is proud to offer the DMC-GH4 as a reliable first camera to professional field photographers, film creators and hybrid photographers.
