The PANASONIC LUMIX G9 MARK II is a flagship mirrorless camera with a Micro Four Thirds sensor that's aimed at both stills photographers and videographers. It's the first ever Lumix Micro Four Thirds G-series camera to use a hybrid contrast and phase-detection auto-focus (PDAF) system. This is a significant improvement over the previous generation, which used a slower contrast-based AF system. The G9 II is capable of shooting in 10-bit 4K up to 120fps and 5.7K up to 30fps.
