err.. I mean... if a friend had dropped my..err..his canon f1.4 50mm on the floor how could I..err..he check it was still ok?
It all looks ok, but not sure how to convince myself...err..him that it is, since I suspect any problems might only show up at wide open apertures - which at 1.4 are highly likely to be difficult to spot as anything other than perfect focussing would look wrong even if the lens was functioning perfectly anyway.
any ideas from anyone before I bite the bullet and buy a replacement anyway? (I am taking it out tomorrow anyway to check, but wondered if there was anything I could do before hand, or is it the case that if it seems to be ok it is?
thanks
