Verdict

The Panasonic Lumix DMC-GH3 is a professional-grade mirrorless Micro Four Thirds camera featuring a 16.05-megapixel Live MOS sensor and a 4-CPU Venus Engine. Key characteristics include a rugged, weather-sealed magnesium alloy body, a high-resolution 1.744M-dot OLED electronic viewfinder, and a 3-inch vari-angle OLED touchscreen. Its main pros are its advanced video capabilities, offering 1080p Full HD recording at up to 60fps with a high 72Mbps bitrate (ALL-I), alongside fast 0.07-second contrast-detect autofocus and extensive physical controls. Some cons include the lack of 4K video recording, a relatively bulky size compared to other mirrorless peers, and underwhelming high-ISO noise reduction performance.
