The Perfect Wide Angle EF Zoom
The Tokina AT-X Pro is an ultra wide-angle zoom has a bright constant F2.8 aperture make viewing and auto focus possible in lower light situations but still maintaining a reasonable size and weight.
Based on the award-winning optical design of the AT-X 124 PRO DX (12-24mm f/4) lens, the new AT-X 116 PRO DX has a slightly shorter zoom range to maintain optical quality at wide apertures.
Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the camera to focus manually. There is no need to change the AF-MF switch, everything is accomplished by the focus ring.
