Tokina AT-X 124 AF Pro DX II 12-24mm f/4 - Canon EF-S, Nikon F (DX) Mount

The Tokina AT-X 124 AF Pro DX II is an ultra-wide zoom lens designed specifically for APS-C (DX) format DSLRs. This 'II' version features an internal autofocus motor, making it compatible with entry-level Nikon bodies that lack a built-in focus motor. It provides a constant f/4 aperture and uses Tokina’s signature 'One-touch Focus Clutch' for switching between AF and manual focus. It is well-regarded for its sharpness and industrial build quality. Verify the operation of the focus clutch, ensuring it snaps cleanly between positions. The internal motor should be quiet and fast; a squealing sound may indicate a failing motor. SDS inspects the zoom and focus rings for smooth travel and checks the glass for coatings damage or internal debris. Ensure the lens mounts securely and communicates correctly with the camera body.
