The Panasonic LUMIX GH5s is the more video-centric version of the popular Panasonic LUMIX GH5, which was itself replaced with the Panasonic LUMIX GH5 II in 2021. The GH5s has a nearly identical weather-sealed body as its sibling, but internally, it uses a lower-resolution 10.2 MP sensor with dual native ISO designed to optimize the camera's low-light performance. It brings back the multi-aspect sensor from older generations like the GH1 and GH2, meaning the sensor is slightly larger than the lens opening, letting you shoot at different aspect ratios without affecting the camera's angle of view. The other big difference is the lack of in-body image stabilization (IBIS), a curious choice that makes sense when you consider that this camera is aimed at professional videographers and filmmakers who tend to use external stabilization. These key changes to the sensor (along with 4k and Cinema 4k at up to 60p, 1080p slow-motion at up to 240 fps, and no recording time limits) make this mirrorless camera a videography powerhouse.
