45mm hands down. I've owned the G2 for years and the 21, 28, 45 and 90 are simply amazing. A sharpness and a character of an almost 3-D look that's appreciated only once seen. The 35mm is good, very good. It's sharp and on paper is impressive. In real life it pales to the rest of the G lens line. It's the only one I bought and then sold.
