So I was reading Steve Huff's 12-50 review - "The little skinny misunderstood kit zoom." Olympus 12-50 | STEVE HUFF PHOTOS and I decided to do some testing. All images were at ISO800 and the crop factor is 100%. 12-50 and G1X at the long end (roughly 60mm): 12-50 and G1X wide open (roughly 12-15 mm): 50-200 and G1X (at roughly 50mm): Arguably the OM-D sensor is better than the G1X, but the kit zoom in the G1X is much better than the 12-50 in the OM-D. With better glass you get better results with the OM-D, but the kit zoom wastes the potential of this camera. Out of the box the G1X is a better setup (focus speed and handling issues aside, although the C (my set) on the control wheel is 10 times better than the MySet menu thing).
