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 imagedescription is natural – that is what LUMIX aspires for.
Video Creation to Meet Pro Quality
The new DMC-GH4 further evolves to meet professional quality and standard with the capability of 4K(Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) video recording in MOV/MP4 or ultra high bitrate video recording at 200 Mbps (ALL-Intra) or 100 Mbps (IPB) without recording duration limit.
Superb Mobility & High Speed Response
Superb mobility and high speed response come equipped with DMC-GH4. The high-precision Contrast AF now integrates DFD (Depth From Defocus) technology to achieve ultra high speed AF of approx.0.07 sec*.The burst shooting power is also boosted to 12 fps(AFS).Both 2,359K-dot LVF (Live View Finder) and 1,036K-dot rear monitor adopt OLED to minimize time lag while enhancing the resolution.
*In AFS, with H-FS14140 or H-HS12035
Reliable Durability
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*.

Expandability for Flexible Usage
To offer more flexible usage, the DMC-GH4 even incorporates Wi-Fi® with NFC Technology or in-camera RAW development capability. It also complies with External Flash (DMW-FL580L), Stereo/Shotgun Microphone (DMW-MS2) or Battery Grip (DMW-BGGH3) to support professional photography/videography. The expansive flexibility of DMC-GH4 goes far beyond the limit of conventional Digital Single Lens Mirrorless camera.
New 16.05MP Digital Live MOS Sensor
The new 16.05-megapixel Digital Live MOS Sensor achieves high quality, high sensitivity image recording with its quick response. Approx.50% higher speed signal readout suppresses rolling shutter effect when using electronic shutter or recording video. Taking full advantage of the Live MOS Sensor, dynamic range is expanded by max.25% at low ISO end. Plus, superior noise reduction allows max.60 min long exposure.
Advanced Image Processor Venus Engine
The image processor Venus Engine is also newly developed dramatically boosting its performance with quad-core CPU that enables high speed signal processing required for rich video recording such as 4K. Integrating superior noise reduction systems, DMC-GH4 enables shooting at max.ISO25600. Sensitivity, gradation performance, resolution and color reproduction are dramatically improved to achieve even higher picture quality.
Focus Peaking
Focus Peaking function shows the peak of focus in MF and AF+MF mode. Users can see the focus position while monitoring the subject in live view. It is also available in remote photo / video shooting with smartphone / tablet via Wi-Fi®.
Highlight / Shadow Control
Highlight and shadow can be separately adjusted with the front/rear dial. 3 patterns of settings can be customized in addition to 3 preset patterns.
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.
Photo Style
You can choose color / texture type for photo / video from Standard / Vivid / Natural / Monochrome / Scenery / Portrait. Contrast, sharpness, noise reduction, saturation and hue parameter for each mode can be adjusted and memorized in camera.
Electronic Shutter & Silent Mode
The DMC-GH4 offers practical electronic shutter. The high-speed signal readout achived by Live MOS Sensor
minimizes rolling shutter effect. The Silent mode switches shutter from mechanical to electronic and turns all sound (AF, operation) off while suppressing emission of AF assist lamp and flash with just a single setting for special shooting occasions.
World’s First* 4K Video Recording
One of the most prominent features of GH4 is unlimited 4K video recording (Cinema 4K: 4096×2160 / 24 fps and QFHD 4K: 3840×2160 / up to 30 fps) in MOV/MP4**.
*For a DSLM as of Feb 7, 2014
** Use SDXC/SDHC Memory Card compatible with UHS Speed Class 3 (U3) when using high bitrate video recording mode of 100 Mbps or greater.
Versatile Video Recording Formats
The DMC-GH4 is also capable of ultra high bitrate video recording at 200 Mbps (ALL-Intra) or 100 Mbps (IPB), which has no recording duration limit. You can freely choose the format from MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates according to the usage. In MP4 / MOV, high quality sound in LPCM (Linear Pulse Code Modulation) is recordable.
Selectable System Frequency
For the global business of professional users, the system frequency can be flexibly selected from 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz.
Real-time Output via HDMI
The DMC-GH4 is also capable of real-time image output (4:2:2 / 8 bit or 4:2:2 / 10 bit) to the external monitor via an optional micro HDMI cable. It is suitable for the professional video making that requires serious monitoring of the imageries. Users can choose to output only the recording content or the content with the setting menus individually depending on a display.When using 4:2:2/10-bit output, simultaneous video recording on SDXC/SDHC Memory Card in the camera is not possible. When using 4:2:2 / 8-bit output, video is recorded in 4:2:0 / 8-bit on SDXC/SDHC Memory Card in the camera.
VFR (Variable Frame Rate)
The VFR (Variable Frame Rate) enables recording video with slow/fast motion such as 96 fps / 4x*, all in Full-HD. See specifications for more effect options.
*In 24p playback.
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.

Color Bars & 1kHz Test Tone
Color Bars (SMPTE / EBU / ARIB Standard) can be the benchmark to fix the color or brightness. 1KHz Test Tone can be the bench mark to fix the sound volume.
Time Code
SMPTE-compliant Time Code either in Rec Run or Free Run count-up methods makes it easy to synchronize the multiple video footage or sound source in the post production workflow.
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.
*In AFS, with H-FS14140 or H-HS12035
High Speed Burst Shooting
The DMC-GH4 boasts high speed burst shooting at 12 fps (AFS) with the maximum recordable images of up to approx. 40 (including RAW) / approx. 100 (excluding RAW) and 7 fps (AFC) to capture fast moving subject just in-focus. Together with the quick start-up and short release time lag, the DMC-GH4 never lets you miss fleeting shooting opportunities.
49-Area AF
Focus detect area is increased from 23 (DMC-GH3) to 49 points for more flexible composition.
Custom Multi AF
