Tokina has also revealed its latest lens for Canon EF and Nikon F mount DSLR cameras, the atx-i 17–35mm F4.
If the specs of this lens look familiar, it’s because it appears to be a successor to the Tokina 17–35mm F4 AT-X Pro FX lens (also available for Canon EF and Nikon F mounts). The new lens is constrcuted of 13 elements in 12 groups, features an aperture range of F4 through F22 and has a minimum focusing distance of 28cm (.9ft).
The lens features Tokina’s exclusive One-Touch Focus Clutch Mechanism, which makes it easy to switch between autofocus and manual focus by pushing and pulling the lens barrel. On the topic of autofocus, the lens uses Tokina’s GMR sensor and Silent Drive-Module (SD-M) motor.
Other features include a 1:4.82 macro ratio, an 82mm front filter thread and ‘moisture protection,’ although Tokina doesn’t elaborate on the extensiveness of its weathersealing specifications.
