Tokina AT-X 28-70mm f/2.8 Pro - Canon EF, Nikon F, Sony A, Pentax K Mount

The Tokina AT-X 28-70mm f/2.8 Pro is a highly regarded professional-grade zoom lens, notable for its bright f/2.8 constant aperture and exceptionally sturdy build. Often compared to contemporary first-party lenses, it features a focus clutch mechanism for quickly switching between auto and manual focus. The optical design is praised for its pleasing rendering and robust metal exterior, making it a favourite for both film and digital full-frame shooters. Check the focus clutch mechanism for smooth operation, as this is a common point of mechanical wear. The internal autofocus motor should operate without excessive noise or hunting. SDS performs checks for internal element alignment and ensures the aperture remains responsive. Like many older pro zooms, check for any significant internal dust or signs of heavy professional use on the mount and barrel.
