I took some shots at small apertures and the images still do not seem sharp. Am I doing something wrong or is it my setup? this is a full sized image taken at f22, iso 100, 1/10 sec shutter speed, tripod mounted and timer. I am disappointed that the signs are not super sharp. f9, 1/160 sec shutter, iso 100, tripod, timer please excuse the crookedness. These are just 2 of many images, but none of them seem sharp to me. Both were taken with a d80 with a 28-200mm f3.5-5.6 lens.
