But this is a bit of a classic overachiever, the Nikkor 80-200/4.5, and honestly it demonstrates both points about technique, but newer shit just being better. It is really quite sharp in the centre in this wide open shot (I think at 85mm) but it is still visibly flawed towards the outside of the frame even at a normal res. Shooting this at f/11 would get a sharp frame, but shooting an EF 75-300mm with af, for $80, would still demolish it. Shooting an IS 70-300mm version for another $60 would just be so much better, as well as both wider, longer and lighter, and with IS you could handhold it too.
