Camera Overview — Panasonic DMC-GH3

The Panasonic LUMIX GH3 is a 16MP Micro Four Thirds mirrorless camera built around a Venus Engine image processor and a sensor capable of capturing stills at a maximum resolution of 4608x3456 pixels. Its ISO range runs from 200 to 12800, giving shooters a reasonable spread of sensitivity options for varied lighting conditions. Burst shooting is supported at up to 6 frames per second, making it a capable tool for action and event photography.

On the video side, the GH3 records up to 1080p at frame rates of 24fps, 30fps, and 60fps in 8-bit color, with Cinelike D and Cinelike V color profiles available alongside the standard option — a meaningful feature for videographers who want a flatter starting point for color grading. The autofocus system combines Phase Detection and Contrast Detection under Panasonic's Light Speed AF designation. The body itself is constructed from magnesium alloy, is weather sealed, and weighs 550g with dimensions of 133 x 97 x 82mm.

A 3.0-inch OLED touchscreen with 614k-dot resolution handles composition and menu navigation, while the electronic viewfinder delivers 1.744 million dots at 60Hz. Connectivity includes Wi-Fi, full-size HDMI output, 3.5mm headphone and microphone jacks, and USB. Battery life is rated at approximately 540 shots.
