Thanks for the comments guys! Glen the 120-300 is very good, the only thing I'd perhaps like is a bit faster AF sometimes (and a zoom ring that goes the 'Nikon' way, I'm forever zooming out when I mean to zoom in and vice-versa

). It's a very heavy (monopod only) lens that's not really practical for everyday use, but it's sharp and combined with the 1.4x TC it works well! Unfortunately it doesn't like the
modified TC17EII as much, AF constantly hunts on both the D200 and D70, although it's still pretty sharp.
