The Panasonic Lumix DMC-GH4 Mirrorless Micro Four Thirds Digital Camera improves on the GH3 with 4K video and double the frames per second photography shooting speed. It is compatible with the versatile Micro Four Thirds mount lens lineup, which is offered in a variety of brands. Videographers have the option to shoot in ultra high bitrate video at 200 Mbps or 100 Mbps without a recording time limit. When recording at 100 Mbps, you will need an SDHC/SDXC memory card capable of handling the transfer speed. Send 4:2:2 8-bit or 4:2:2 10-bit video in real time to external monitors or recorders on set via the micro HDMI output. An optional micro HDMI cable is required and not included. Additional video features include focus peaking, time code support, and cine-like gamma options. Additionally, Variable Frame Rate, time-lapse, and stop motion animation videos can be recorded internally without the need for additional post-production processing. An Eye Sensor automatically switches between the Live Viewfinder and the rear monitor for easy shooting with both. Silent Mode switches the shutter from mechanical to electronic and turns off sounds while suppressing the AD assist lamp and flash with just a single setting. This camera is ideal for videographers who also want a robust photography system
