The GX85 is a very neat camera for its size and price. When I first saw footage from my S5 I couldn’t believe my eyes though. It just was night and day in terms of color, image quality, noise and dynamic range. I wouldn’t go back to the GX85 as my only camera, it’s not bad at all as a portable cam but the S5 is just miles better. So is the S1, though admittedly and unfortunately larger and heavier.
