Tamron AF 28-80mm f/3.5-5.6 Aspherical (177D/277D) - unknown Mount

The Tamron AF 28-80mm f/3.5-5.6 Aspherical (Models 177D/277D) is a lightweight standard zoom lens produced for various AF film and digital SLR mounts. Utilising aspherical elements to reduce aberrations, it was designed as a compact and affordable alternative to manufacturer kit lenses. The lens construction is primarily plastic, including the mount in many versions, to keep weight to a minimum. When inspecting a used 177D or 277D, focus on the autofocus motor performance, which can become noisy or hesitant with age. The plastic mounts should be checked for any chipped tabs or excessive wear. SDS technicians test the electronic communication with the camera body and ensure the zoom mechanism moves freely without snagging. Check for any wobbling in the front lens barrel when extended.
