I too have a Tokina ATX 400mm f5.6. It is one of the few non-Nikon lenses that I own.

I have been very pleased with its image quality, its handling, its construction, and its 72mm filter size.

The only thing I do not like about this lens is the slow f/5.6 maximum aperture. However, I do not shoot enough telephoto to justify the purchase of the f/2.8 400mm Nikon lens.

However, as much as I try, I have not yet figured out how to run film through my lens.
