Mike. Shoot at iso 100 in low light and use the force. I have been amazed at the low light capability at 1/20 of the 20mm. It is a fast lens. I do under expose 1/3 stop as a rule. And I have used the 45-200 at the same settings and I am not as steady as I used to be. but the images are sharp sharp sharp. This camera amazes me. Easily as sharp as the sony 900 IS and the tonality is special.
