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.

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: 4096x2160 / 24 fps and QFHD 4K: 3840x2160 / 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.*1 *2 In addition, a variety of practical functions required for professional video recording are newly integrated.

*1 Motion image can be recorded up to 29 min 59 sec depending on the recording format and the camera’s sales area.
*2 Use SDXC/SDHC Memory Card compatible with UHS Speed Class 3 (U3) when using high bitrate video recording mode of 100 Mbps or greater.

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 to12 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.

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.

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^*1 4K Video Recording

One of the most prominent features of GH4 is unlimited^*2 4K video recording (Cinema 4K: 4096x2160 / 24 fps and QFHD 4K: 3840x2160 / up to 30 fps) in MOV/MP4^*3.

*3 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*1 *2. 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.

*1 Motion image can be recorded up to 29 min 59 sec depending on the recording format and the camera’s sales area.
*2 Use SDXC/SDHC Memory Card compatible with UHS Speed Class 3 (U3) when using high bitrate video recording mode over 100 Mbps.

Video Recording Formats

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.

Professional Video Functions

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.

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.

Wi-Fi^® with NFC Technology

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 (Optional)

The Interface Unit(DMW-YAGH) is offered exclusively for professional 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 camera is not possible.
