Hi Christopher,

400mm f/5.6? I am interested in any opinions..."
I own the Tokina 400mm f/5.6 Manual focus that I use on my F301 and
F801s.
Mechanically it is very well built: heavy, well balanced, it has a very
smooth and wide focus ring and a built in lens hood. Only the tripod
mount is a little undersized, not so firm.
Optically, in my opinion, it is only a medium performer. Its sharpness
is not impressive.
If you find this lens used and low priced (I bought mine for about 220
US$) and intend to use it for leisure, buy it.
If you mean to do critical works go for a Nikon MF 400 5.6 IF used, at
least.
