Panasonic Lumix G2. 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 G2 Review. Nearly all these photos were shot in RAW and converted to DNG with Adobe Lightroom 3 and then processed in LR 3. I do JPG once in awhile, but as a general rule, I shoot RAW. I have an ISO test in another gallery HERE.
