The Panasonic Lumix DMC-GX1 is an enthusiast-oriented model that bears more than a passing resemblance to the Lumix DMC-GF1. The GX1 sports a 16MP 'Live MOS' sensor, a maximum ISO sensitivity setting of 12,800, a touchscreen interface and a revamped AF system. The GX1 is also the first camera compatible with Panasonic's brand new high-resolution LVF2 viewfinder, sold separately. The GX1 is a camera that gets a whole lot right. Assessing it against its true predecessor, the GF1, you'd have to look very hard to find areas in which it does not represent a clear improvement. Panasonic has addressed almost every criticism of its early generation G-series cameras in a package that, when paired with its collapsible kit zoom is among the most pocketable cameras in its class.
