Pentax smc Pentax 67 135mm f/4 Macro - Pentax 67 Mount

The 135mm f/4 Macro is a specialised lens for the Pentax 67 system, offering a life-size magnification ratio of 1:3.1 (or higher with extension tubes). It is designed to deliver high resolution at close focusing distances, making it ideal for product work and detailed nature photography. The lens features a large, tactile focus ring and the robust build quality characteristic of the 67 line. Check the long focus helicoid for smooth movement, as macro lenses often require significant travel. SDS inspects for internal dust and ensures the diaphragm blades are clean and dry. Given the weight of the lens, ensure the bayonet mount shows no signs of warping. Verify that the aperture scale is legible and that the auto/manual switch functions correctly.
