The GH4's new Live MOS Sensor and Venus Engine team up to reduce noise while raising resolution and improving colour reproduction. As the world's first* DSLM camera to record 4K videos, it truly meets the needs of professionals.
*For a digital single lens mirrorless camera as of February 7, 2014.
The DMC-GH4 offers a practical electronic shutter. The high-speed signal readout achieved by the Live MOS Sensor minimizes the rolling shutter effect. Silent mode switches the shutter from mechanical to electronic and turns all sounds (AF, operation) off while suppressing emission of the AF assist lamp and flash with just a single setting for special shooting occasions.
The new 16.05-megapixel Digital Live MOS Sensor achieves high quality and high sensitivity image recording with its quick response. Approx. 50% higher speed signal readout suppresses the rolling shutter effect when using electronic shutter or recording video. Taking full advantage of the Live MOS Sensor, dynamic range is expanded by 25% (max) at the low ISO end. Plus, superior noise reduction allows 60 minutes (max) long exposure.
The newly developed Venus Engine image processor dramatically boosts its performance with a quad-core CPU that enables high speed signal processing required for rich video recording such as 4K. Integrating superior noise reduction systems, the DMC-GH4 enables shooting at Max. ISO 25,600. Sensitivity, gradation performance, resolution and colour reproduction are dramatically improved to achieve even higher picture quality.
The Focus Peaking function shows the peak of focus in MF and AF+MF mode so users can see the focus position while monitoring the subject in live view. It is also available in remote photo / video shooting with a smartphone / tablet via Wi-Fi
Highlight and shadow can be adjusted separately with the front/rear dial. Three settings can be customized in addition to 3 preset patterns.
The DMC-GH4 is capable of developing RAW image in-camera. In addition to the colour space setting (sRGB / AdobeRGB), the parameter of white balance, exposure compensation, contrast, highlight / shadow, saturation, noise reduciton, sharpness or hue can be adjusted while applying LUMIX's Photo Style, Intelligent D-range Control or Intelligent Resolution.
You can choose colour/texture type for photo/video from Standard / Vivid / Natural / Monochrome / Scenery or Portrait. Contrast, sharpness, noise reduction, saturation and hue parameter for each mode can be adjusted and memorized in-camera.
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 from MOV, MP4, AVCHD Progressive and AVCHD formats with 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 Cards compatible with UHS Speed Class 3 (U3) when using high bitrate video recording mode over 100 Mbps.
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 professional video making that requires serious monitoring of imagery. Users can choose to output only content being recorded or content with the menu depending on the display.
* When using 4:2:2 / 10-bit output, simultaneous video recording on SDXC/SDHC Memory Cards is not possible.
When using 4:2:2 / 8-bit output, video is recorded in 4:2:0 / 8-bit on SDXC/SDHC Memory Cards.
VFR (Variable Frame Rate) enables recording video with slow/fast motion at 96 fps / 4x (in 24p playback), in Full HD.
Time Lapse Shot and Stop Motion Animation are available for observation of stationary subjects or for producing a stop motion (stop frame) video with sequential pictures. Both can be produced in-camera without post-production processes.
The Contrast AF system is advanced with the DFD (Depth from Defocus) technology which even shortens the time to focus. The DFD calculates the distance to the subject by evaluating 2 images with different sharpness levels while consulting the optical characteristics data of the current lens in a moment. As a result, ultra high speed AF of approx. 0.07 sec (In AFS, with H-FS14140 or H-HS 12035 lens) is achieved. This improvement benefits more as focal length increases.
The DMC-GH4 boasts high speed burst shooting at 12 fps (AFS) with maximum recordable images of up to approx. 40 (including RAW) / approx. 100 (excluding RAW) and 7 fps (AFC), to capture fast moving subjects just in-focus. Together with the quick start-up and short release time lag, the DMC-GH4 never lets you miss fleeting shooting opportunities.
Focus detect area is increased from 23 (DMC-GH3) to 49 points for more flexible composition
With Custom Multi mode, you can freely select the blocks to focus on out of the 49 focusing areas.
In addition to the conventional Face Recognition AF, the DMC-GH4 newly incorporates Face/Eye Detection AF which automatically sets focus on the face or eyes.
The 1-area AF can be seamlessly magnified not only in manual focus, but also in auto focus mode.
The DMC-GH4 boasts newly developed high-precision, high speed dual OLED (Organic Light-Emitting Diode) displays. Increasing the resolution of the display to 2,359K-dots, the LVF (Live View Finder) boasts approx. 1.34x / 0.67x (35 mm camera equivalent) magnification and 3.0-inch. 1,036K-dot, free-angle rear monitor. They 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.
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 a 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*. It offers a high shutter speed (max. 1/8000 second), not only to capture spur-of-the-moment, fast moving subjects, but also uses the high speed lens with open aperture even outdoors to give impressive defocus. Both the built in / external flash can be synchronized with max.1/250 second shutter speed.
*Panasonic in-house examination.
For quick, intuitive control, 3 dials are located on the top and back of the camera and the main dial now comes with a lock structure. A dedicated button allows direct reach to exposure compensation, white balance adjustment or ISO setting and settings can be assigned to the Fn button (max. 5). All of these external controls are designed to be operated easily without taking your eyes off the viewfinder.
The DMC-GH4 comes with a variety of connection terminals for flexible shooting options: 3.5 mm MIC and 3.5 mm headphone jack.
The DMC-GH4 is 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 2.5 mm jack for remote controller are available. It complies with the SDXC / SDHC Memory Cards UHS Speed Class 3 (U3).
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 a compatible smartphone / tablet. It is also easy to embed geotag in the image after shooting. For a smartphone / tablet without NFC, the camera displays a dedicated QR code on its monitor to complete pairing easily by reading/scanning the code.
For the global business of professional users, the system frequency can be selected from 59.94 Hz (23.98 Hz) / 50.00 Hz or 24.00 Hz.
