Gordon from CameraLabs published the full review:
If you’re unlikely to ever fit a different lens from the kit zoom, you could enjoy similar quality and features from one of the many premium compacts around with 1in sensors – such as Panasonic’s own LX10 / LX15 – and these will also better squeeze into a pocket. But if you are wanting to swap lenses at some point, the Lumix GX800 / GX850 represents one of the most affordable points of entry around and comes recommended.
Compact, lightweight body with swappable lenses.
Crisp, detailed and relatively low noise 16 Megapixel photos.
4K movies and 4K Photo modes with post focus adjustments.
Touchscreen tilts up to face subject for selfies and vlogging.
Fast single autofocus that works in very low light.
Screen doesn’t tilt down and becomes hard to view in bright conditions.
No built-in viewfinder (but not surprising at this price).
Optical stabilisation on kit zoom not as effective as other lenses.
No mic input (again not surprising, but great for vloggers).
Micro SD slot won’t work with any full size SD cards you might have.
Panasonic GX850 is in Stock at Amazon, BHphoto, Adorama and Panasonic store.
