Tokina AT-X 124 PRO DX II 12-24mm f/4 AF lens exclusively for Digital SLR cameras with APS-C sensors.* This lens gives the Digital photographer an ultra wide-angle zoom lens that has the equivalent angle of view to an 18-36mm in full frame format.
The model II The Nikon mount AT-X 124 PRO DX II has a built-in AF motor drive. The motor inside the lens was loaded onto the Nikon mount specification anew. The AF operates smoothly and quietly due to a DC motor that uses a new AF control gear assembly. With the built-in motor, the lens can be used in AF mode with the Nikon D60 and D40 and other silent wave bodies.
In addition the DX II Version offers an improved multi-coating. The new multicoating helps reduce reflections that can cause flare and ghosting even more than in the AT-X 124 PRO DX.
The AT-X 124 PRO DX II features the one-touch focus clutch mechanism. To use the one-touch focus clutch mechanism, move the focus ring forward, towards the front of the lens, for AF or back for MF. This allows for a fast and easy manual over-ride in difficult lighting situations.
* The lens is designed for Digital cameras with APS-C sized CMOS and CCD sensors (DX) , not designed for cameras with Full Frame sensors (FX).
