    Evening all:

    After buying a new lens the other day I was wondering if anyone could tell me what the best way is to test the lens sharpness out to find out if I got a good or bad copy of the lens? Is there certain settings that are better to use on certain subjects.

    If anyone has any ideas I sure could use the asisstance.

    Thanks in advance all.

    Either print out a sharpness indicator, or point the lens at a screen door. A lens will react very different at every aperture and focal length.

    Remember to rule out all problems. So you MUST use a tripod at higher apertures, ISO100, and use mirror lockup feature and a cable release.

    In reality though if you got a bad copy of a lens it should be pretty obvious, if not then your sharpness will probably be similar to www.photozone.de 's graphs.
