The Panasonic Lumix DMC-GH4 Mirrorless Micro Four Thirds Digital Camera is a true hybrid camera designed for both professional photo and video use.  It also features built-in Wi-Fi with NFC technology, in-camera creative controls, and a high-speed 49-point autofocus in both photo and video mode. The GH4 delivers video quality surpassing many professional video cameras. Video can be recorded in a variety of formats, from efficient AVCHD and AVCHD Progressive, to 200 Mbps All-Intra and 100 Mbps IPB MOV and MP4 formats. Video recorded to SD cards is 4:2:0 8-bit. Real-time 4:2:2 8-bit and 4:2:2 10-bit video can also be sent to an external monitor or recorder with an optional micro HDMI cable.

Additional video features include focus peaking, timecode support, and cine-like gamma options. The GH4 comes with a rechargeable lithium-ion battery pack, battery charger with AC cable, body cap, hot shoe cover, USB cable, shoulder strap, and DVD with supplied software. The increased signal speed readout helps to suppress the effects of the rolling shutter. In conjunction with the quad-core Venus Engine image processor, you'll enjoy dramatically improved sensitivity (maximum ISO 25600), gradation performance, resolution, and color reproduction. The DMC-GH4's 4/3" type sensor is large enough for shallow depth of field and yet small enough to take advantage of lighter, more compact lenses than a larger format camera would require.

An Eye Sensor automatically switches between the Live View-Finder and the rear monitor, for easy shooting with both. The DMC-GH4 features a magnesium alloy full die-cast front and rear frame. A splash and dustproof design are achieved by tightly sealing the joints and control components.  The app also lets you embed location data into an image after shooting. If your mobile device isn't NFC compatible, you can still connect to the camera by scanning a QR code displayed on the GH4's monitor. The high-precision Contrast AF integrates DFD (Depth from Defocus) technology to achieve AF speeds of approximately 0.07 sec in AFS mode. 

This is useful when capturing photos in situations where noise and light from the camera would be a distraction to performers or people around you. The DMC-GH4 brings the GH-line into the 4K age by offering both 16:9 UHD 4K 3840x2160 video at 23.98p, 24p, or 29.97p, and 17:9 DCI (Digital Cinema Initiatives) 4K 4096x2160 videos at 24p. The Interface Unit attaches to the bottom of the camera and provides 2 XLR input terminals, for line or condenser microphones, with independent volume controls and an audio level display monitor.
