Panasonic Lumix GH4 - Features
The newly developed 16.05-megapixel Digital Live MOS Sensor for DMC-GH4 excels both in sensitivity and response and suppresses the "rolling shutter‟ effect even when using electronic shutter or recording motion images.
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 to set focus to achieve an ultra-high speed AF of approx. 0.07 secviii. The speed of burst shooting is also dramatically faster than the DMC-GH3, with high speed burst shooting at 12fps (AFS) and 7.0 fps (AFC). The maximum number of recordable images in burst shooting is up to 40 shots (including RAW) or 100 shots (excluding RAW), before the rate slows down.
As well as Face Recognition AF, the DMC-GH4 now incorporates Eye Detection AF, which allows the user to select which eye the camera focuses on. In addition, focus points are increased from 23 (DMC-GH3) to 49 points for more flexible composition, together with Custom Multi mode allowing users to freely select the blocks to focus on from out of the 49 focusing areas.
Enhanced OLED and LVF resolution
The DMC-GH4 has newly developed high-precision, high-speed dual OLED (Organic Light-Emitting Diode) displays for the 2,359K-dot LVF (Live View Finder) and 1,036K-dot rear monitor. Both LVF and rear monitor use OLED to achieve high speed response with minimum time lag while enhancing the resolution. Notably, the OLED for the LVF boasts a 10,000:1 high contrast ratio for superior color reproduction, with excellent visibility.
RAW data development in-camera
The DMC-GH4 offers the convenience of processing RAW photos in-camera with parameter adjustments, so photographers in the field can apply their favourite settings to the RAW file and rapidly create a JPEG for sharing. In addition to the color space setting (sRGB / AdobeRGB), the parameters of white balance, exposure compensation, contrast, highlight/shadow, saturation, noise reduction, sharpness or hue can be adjusted; and Photo Style, Intelligent D-range Control and Intelligent Resolution can also be applied.
Convenient range of optional accessories available
Impressive professional video features
he DMC-GH4 offers unlimited 4K video recording (Cinema 4K: 4096x2160 / 24 fps) and QFHD 4K: 3840x2160 / up to 30 fps) in MOV/MP4v. The DMC-GH4 is also capable of recording Full- HD video with an ultra high bitrate at 200 Mbps (ALL-Intra) or 100 Mbps (IPB), which does not have a recording time limit. Video formats available include MOV, MP4 (LPCM), AVCHD Progressive and AVCHD at a variety of frame rates according to usage. For global use, the system frequency is selectable between 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz.
Just some of the many features that will give the DMC-GH4 amazing appeal for movie making professionals are:
- Focus Peaking
- Variable Frame Rate at 96 fps
- HDMI Monitor at 4:2:2/10-bit
- Zebra Pattern
- Time Code
- Cinelike Gamma
- 1kHz Test Tone and Colour Bars (SMPTE/EBU/ARIB Standard)
- Master Pedestal adjustment
Interface Unit (AG-YAGHG)
Panasonic has developed an Interface Unit (AG-YAGHG) exclusively for professional workflow with the DMC-GH4, enabling more powerful video transmission. It complies with Full HD (4:2:2 / 10-bit) four parallel outputs and these can be used for 4K (4:2:2 / 10-bit) output - both with time codevi. The XLR input terminals (2ch) are also equipped to connect a line or condenser microphone. When connecting with a microphone, volume can be controlled for L and R separately, and can be monitored via the LED audio level display on the back of the unit. The 12V DC IN is highly compliant with large-capacity professional batteries and continuously supplies the DMC-GH4 with powervii.
