Tokina AT-X 20-35mm f/2.8 AF Pro - unknown Mount

The Tokina 20-35mm f/2.8 AF Pro is a professional wide-angle zoom for full-frame cameras. It belongs to the 'Pro' series, characterized by high-grade materials and a rugged metal exterior. The f/2.8 aperture provides good low-light performance and shallow depth of field at 35mm. It utilizes an internal focusing mechanism, meaning the lens does not change length during focus, and it incorporates the one-touch focus clutch. Used units should be examined for smoothness in the zoom ring, which is often very well-damped. SDS checks for oil on the aperture blades and ensures the diaphragm snaps shut instantly at all settings. Given the age of this model, we also look for internal dust or light haze. Verify that the mount is in good condition, as the weight of the all-metal construction can put stress on the camera mount if the lens has been mishandled.
