Tokina 28-85mm f/4 - Canon FD, Nikon F, Pentax K, Minolta SR, Olympus OM Mount

The Tokina 28-85mm f/4 is a constant aperture standard zoom lens from the manual focus era, often found in various mounts including Nikon AI and Canon FD. It features a robust all-metal construction and a one-touch pump action design for both zooming and focusing. It is well-regarded for its mechanical build quality and provides a versatile range for general-purpose film photography, maintaining its f/4 aperture throughout the zoom range. When inspecting a used copy, the zoom action should be checked for 'creep', where the barrel slides under its own weight. Internal dust is common in these push-pull designs, though it rarely impacts image quality. SDS technicians verify the aperture blades are snappy and free from oil, and check for any signs of internal haze or fungus which can develop in older optics.
