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.
The Canon version of the lens already has a built-in AF motor and will benefit from the improved multi-coating.
