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

The Tokina 12-24mm f/4 is a wide-angle zoom lens designed for APS-C (DX) format digital SLRs. It offers a constant f/4 maximum aperture throughout the zoom range, providing consistent exposure and depth of field control. The optical construction includes aspherical elements and SD glass to minimise aberrations and maintain sharpness. Its standout feature is the One-Touch Focus Clutch mechanism, allowing users to switch between auto and manual focus by sliding the focus ring. When buying a used AT-X 124, check the focus clutch mechanism for smooth operation, as it can occasionally become stiff or gritty. SDS technicians inspect the internal lens elements for dust and haze, which can sometimes occur in earlier Tokina designs. Ensure the mount contact pins are clean to prevent communication errors with the camera body. We also check for any zoom creep or excessive play in the lens barrel.
