Panasonic Lumix GH2. This is an interchangeable lens camera with a full size four thirds image sensor, but it has the micro four thirds lens mount (smaller lenses) and no mirror assembly for a viewfinder, making the camera smaller. Lumix GH2 Review. The GH2's claim to fame is its great full HD (1080p) video. Nearly all these photos were shot in RAW and converted to DNG with Adobe Lightroom 3 and then processed and exported as JPG. I do JPG in-camera once in awhile, but as a general rule, I shoot RAW. I have an informal ISO test for the GH2 HERE
