not scientific or anything. Am going back out tonight to shoot downtown. I barely missed Dave Chappelle downtown last night didn't even know he was going to be there... first two are with is the 10-20mm, the second one with the 55-250mm and the last one is with the 18-55IS. all test, please keep in mind so far, i highly recommend all three lenses, oh and the camera as well. Night shots were about 15-20 seconds long, and MLU was used. All were shot in manual.
