Of course I didn't expect the same kind of performance as a $$$$ Nikkor lens would give me. So I wasn't disappointed.But I had hoped for better results -- I put it on a tripod to avoid vibration focusssed as exactly as possible onto a high-contrast banner at a race track. But still I never could a sharp edge from that banner.Using the same setup & procedure with a different lens, sharpness jumped a lot. Price of that lens also jumped a lot.I cannot recommend it on D80 and lower as this is a non-CPU lens and metering will not work so it is 100% manual and try & error. The D200 can meter in "M" mode.
