We've reviewed the following Panasonic cameras (click on the linked camera names below to be taken to the review):
So What Would Thom Get? The GH5 and its GH5S sibling are the tour-de-force when it comes to video, including 4K video capabilities, and they have great autofocus performance with many Panasonic lenses due to careful tuning. For low light video, get the GH5s version (I wouldn't buy it for stills). And as a more general purpose camera at a lower price, the G9 is very good.
There's really not a stinker in the current cameras, so choose a Panasonic body based upon how it fits into your shooting style. Panasonic has made serious strides in almost all their model lines over time, so keep to current models whenever possible.
