remembered this post for 2012! the filter absorbed some impact and the lens was repairable instead of a total loss.
Debate is getting silly...
If front element nicks and prints are not enough to effect you IQ how on earth is a good quality filter enough? At least be consistent... in your logic. Its no big deal or the end of the world lol.
dude a
52mm B&W is $25... assuming the used AF-D version because that is the only one in that price range.
Yes, but the "invisible" fence is still there, its light rays are just spread out, lowering contrast and sharpness of the entire image. So to say "scratches don't effect the image" is just wrong. They do, you either don't notice or its so minor it can be corrected.
