p/s: is this lens noisy with the IS on? My lens was very noisy on the 20D body. Not yet try it on 5D.
YES YES this lens is noisy , but what people told me was all the IS lens will have that noise.
Its not really noisy, but it just annoys me that IS motor turn after you take a picture...
Not at all good for low light condition, even inside home. If you add speed light -- sharp ....
at first - it scared the hell out of me..
