Pentax smc Pentax-A 645 80-160mm f/4.5 - Pentax 645 Mount

The smc Pentax-A 645 80-160mm f/4.5 is a medium format zoom lens designed for the Pentax 645 system. It offers a versatile telephoto range, roughly equivalent to 50-100mm in the 35mm format, making it a flexible tool for studio work and landscapes. As an 'A' series lens, it supports shutter-priority and programmed AE modes on compatible cameras through its electronic contacts and aperture ring. Due to the weight of the internal glass, these lenses can occasionally develop zoom creep or mechanical wear in the helicoids. SDS checks for smooth operation throughout the zoom and focus ranges. We also inspect the aperture blades for oil and ensure the electrical contacts are clean to maintain communication with the camera body. Internal dust is common in zooms of this era but is checked for excessive levels.
