Panasonic's Lumix G7 is a small camera with serious 4K chops

Panasonic has been a huge proponent of 4K-ready cameras, starting with the Lumix GH4 and LX100. A few days ago, the Lumix G7 joined that group. The recently introduced Micro Four Thirds camera features a 16-megapixel Digital Live MOS sensor, an ISO range of up to 25,600 and a quad-core CPU for speedy image processing.

But here's the one thing it does best: 4K. More specifically, I'm talking about Panasonic's 4K Photo feature, which lets you extract high-resolution pictures from 4K, 30 fps videos and save them at an 8-megapixel equivalent. This is particularly useful when you shoot moving subjects, as you're able to record a 4K video (roughly up to 30 minutes), choose whatever frame you want from it and save that to the camera's SD card. Is it cheating? Perhaps, but it works perfectly.
