I was reading a couple of reviews on the B&H site, see:
when I found this snippet:
...All focal ranges benefit from stopping down. F/8 yields great results, but again, beyond 500mm, although improved, it is still not good enough for me. In fact, in every case that I shot, taking the shot at 500mm and cropping to the same field of view as 600mm, then interpolating the extra resolution in Photoshop yielded a sharper photo with more detail. So although 600mm might be good enough for some people, why bother when you can shoot at 500mm and up-res with better results?
Does this make sense? Can anyone confirm this being true with their lens? From my understanding the IQ does drop off by more then a little bit as it approaches the 600mm end.
