Pentax SMC Pentax-A 28-80mm f/3.5-4.5 - Pentax K Mount

The SMC Pentax-A 28-80mm f/3.5-4.5 is a manual focus zoom lens that bridges the gap between wide-angle and short telephoto. Featuring a macro mode at the 80mm end, it offers increased versatility for close-up work. The 'A' series designation ensures compatibility with Program and Shutter Priority modes on supported Pentax cameras. It is built to a higher standard than later plastic AF zooms, offering a more traditional feel. When inspecting a used 28-80mm 'A' series, pay close attention to the macro switch mechanism, as this can sometimes become stiff or jam. SDS verifies that the aperture blades are clean and that the electronic contacts for the 'A' setting are functional. Check for smoothness in the zoom action and ensure the front element is free from cleaning marks or coating damage.
