Hi all. I'm curious about how the 400 f/3.5 behaves on a modern DSLR. Specifically, Bjørn raises concerns about chromatic aberration on a D200/D2x, but I'm unclear whether this refers to lateral chromatic aberrations (which a more modern body would fix automagically, and which is trivial to correct in post) or longitudinal chromatic aberration (which is harder to hide - I consider the bokeh to matter for a lens of this specification). Anyone tried such a combination? It may be the nearest to a 400 f/2.8 I'd be able to afford in the forseeable future - not that I'm shopping just yet - and for portraits and some wildlife I might get away without needing AF and VR. I'm thinking mostly full-frame (D700), if that makes a difference. I'm not expecting sharpness to match the 400 f/2.8 VR, but I'll take what I can afford. Or at least, not afford, but by less. Thanks in advance.
