Samsung GX-20 Review


Price as reviewed:



The GX-20 can be viewed as the fruit of a successful manufacturing partnership. Samsung’s electronics expertise has been coupled with Pentax’s long-standing photographic heritage to produce a camera that manages to meet a high specification while not breaking the bank.

The semi-pro/prosumer specification that made the former a hit has been bolstered with the boost in resolution of the sensor, while further interface and usability tweaks make the GX-20 easy to use. The fully weatherproofed body is a real asset, and, along with the increased resolution, mean the GX-20 would be at home with the enthusiast photographer in field or studio.
