The Panasonic GH4 is a professional-grade hybrid photo/video camera for the Micro 4/3 system. Looking for an updated version of this camera? Check out the GH5 and GH5S. Key features include:
- 16.05MP Live MOS sensor and Venus Engine processor
- 4K video capture in 16:9 and 17:9
- Ultra-high bit-rate Full HD video capture
- The fast, high-precision autofocus system
16.05MP Live MOS Sensor. The 16.05MP Micro 4/3 sensor delivers high-quality images with high sensitivity and quick response times. The increased signal speed readout helps to suppress the effects of the rolling shutter, and the quad-core Venus Engine image processor provides improved sensitivity, gradation performance, resolution, and color reproduction.
4K Video. The GH4 offers 4K video capture in both 16:9 (3840 × 2160) and 17:9 (4096 × 2160) aspect ratios. You can record 4K video as MOV or MP4 files in a high bit rate 100 Mbps IPB codec. Do note that shooting 4K at 100 Mbps requires a UHS Speed Class 3 memory card. The camera can switch system frequencies from 59.94 Hz (23.98 Hz) and 50 Hz, and you can also use 24 Hz frequency for true 24 fps cinematic video. For even more flexibility, the optional Panasonic DMW-YAGH Interface Unit (no longer a rentable product) gives you two XLR inputs and four SDI outputs (two 3G-SDI & two HD-SDI).
Versatile HD Recording Formats. The GH4 records ultra-high bit rate HD video at 200 Mbps (All-Intra) or 100 Mbps (IPB), as MOV/MP4/AVCHD Progressive/AVCHD at a variety of frame rates. All internally recorded video codecs use 4:2:0 color sampling and an 8-bit color depth, and you can send real-time 4:2:2 8-bit or 4:2:2 10-bit video to external monitors or recorders via micro HDMI.
Fast Autofocus. The high-precision Contrast autofocus integrates Depth from Defocus (DFD) technology to achieve AF speeds of approximately 0.07 sec in AFS mode, enabling the camera to shoot bursts of 12 fps in AFS mode. The 49-point system provides more flexibility when composing shots, with a Custom Multi mode that allows custom selection of what focus points to prioritize.
Pro-Grade Build. The magnesium-alloy body features a dust- and splash-proof design that complements the many native Micro 4/3 weather-sealed lenses.
