Tokina AT-X 270 AF PRO 28-70mm 1:2.6-2.8
The Tokina AT-X 270 AF PRO 28-70mm 1:2.6-2.8 lens is a fast zoom lens, that was made with Nikon AF-D, Canon EOS, Minolta AF and Pentax AF mount.
The optical formular of this lens, and its successor the AT-X 270 AF PRO II, comes from the famos (and expensive) Angenieux AF 28-70mm 1:2.6.
The difference between the AT-X 270 AF PRO and the PRO II is the bayonett hood, the crincle finish and the better multicoating. Resulting in better flare resistence of the PRO II.
