The Panasonic Lumix DC-GH5S has a great looking image with a two-stop improvement in low-light performance over its brother the GH5, but it comes at a cost. On top of costing $500 dollars more than the GH5, the GH5s uses a sensor with half the pixels and loses the sensor stabilization.
If you want a camera that can also shoot photos, the GH5s isn’t a great choice. However, if you are a video-first shooter, the GH5s is for you. The feature list is strong with the GH5s, and it’s likely that you could ignore its downfalls and get along quite well.
