Panasonic Lumix GH4

List Price: $1,699 (body only)

INTRODUCED 2/2014

Panasonic’s new LUMIX GH4 looks much like its GH3 predecessor, but features a new 16-megapixel Digital Live MOS sensor and Venus Engine with quad-core CPU that make possible 4K video. Yes, this mirrorless camera can shoot 4096×2160 cinema 4K at 24 fps, and 3840×2160 QFHD 4K at 30 fps, in MOV/MP4 format. Images are stored on SD/SDHC/SDXC media; Panasonic recommends UHS Speed Class 3 for 4K video (the camera can shoot 200 Mb/s All-Intra or 100 Mb/s IPB). The camera can also stream real-time 4:2:2 8-bit or 10-bit video to an external monitor or recorder.

The GH4 comes in an easy-to-hold "mini-DSLR"-style form factor. A high-resolution OLED electronic viewfinder provides convenient eye-level operation for both still and video. There’s also a free-angle, 3-inch OLED touch-screen monitor for easy odd-angle shooting.

As a still camera, the GH4 shoots excellent images, delivering 14-bit RAW, as well as JPEGs at 16 megapixels, at up to 12 fps (in AFS mode) or 7.5 fps with continuous autofocusing. Using the electronic shutter, shooting rates as high as 40 fps are possible. Normal ISO range is 200-25,600, with 100 also available in expanded mode. Quick contrast-based AF featuring DFD (Depth From Defocus) technology is available for both still and video shooting, with focus as quick as 0.07 seconds.

The GH4 features a rugged die-cast magnesium-alloy body and a shutter tested to 200,000 cycles. Mechanical shutter speeds run from 60 to 1?8000 sec., with flash sync up to 1?250 sec.

Dimensions are 5.2×3.7×3.3 inches and 16.9 ounces.
