<p>I am using the AF-I 300mm f2.8 with my D300, D700 and D800 cameras. I find it to be an excellent lens and as long as you test it before you buy I can not see you going wrong with it. It focuses fast (I have not used newer 300mm lenses to compare), and is very sharp. I find it also to work very well with the AF-I TC-14 and TC-20 III converters. Make sure you get the lens hood with it and a L37c filter inserted in the filter holder. Mine was mint when I bought it and I paid the same as a new AF-S 70-300 VR. Well worth it!<br>
