ok i just picked up a used copy of this lens with cpl and a uv and the moment i put it on my 60d it was veryyyy noisy,i was so shocked i istantly thought something was wrong,after googling and reading mannnnny posts it seems this is normal,now i know thius isnt canon top of the line lens but really that noise is normal,my 2 kit lens with is dont make a peep and the sigma 17-50 os ex is whisper quiet with is on,i like the lens and i guess im keeping it as i already paid for it but im a little shocked canon could release something like this in a l series,anyone else have a very noisy copy
