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. The Canon version of the lens already has a built-in
AF motor and will benefit from the improved multi-coating.
The optical system of original AT-X 124 PRO DX won awards for its sharpness world-wide.
This design was maintained in the AT-X 124 PRO DX II and improved with the introduction
of new multi-coating system. The new multi-coating 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. Digital single-lens reflex DX lens dedicated
to digital SLR cameras with APS-C sized sensors.
