Testing for Lens Sharpness?
wondering if any of you can help me out here, i have with me a 28-70 nikon f2.8,
shooting using a d200 body.
but am starting to wonder if there is something wrong with my copy (lens),
images come out rather soft, even when shot at f4.5
is there a way to comfirm my suspicions? say, a lens sharpnes chart, etc..and how do i go about using it, thanks!
I guess this will come in handy for those who plan to get a "sharp" copy when purchasing at the shops as well,
Hope to receive some inputs,

Re: Testing for Lens Sharpness?
The problem is, lens sharpness is a total of many things, and not just resolution.
