Pentax SMC Pentax-M 28-50mm f/3.5-4.5 - Pentax K Mount

The SMC Pentax-M 28-50mm f/3.5-4.5 is an exceptionally compact wide-to-standard zoom lens from the 'M' series era. Designed with portability in mind, it is barely larger than some prime lenses of the period. It offers a useful, albeit modest, zoom range for street and travel photography on manual focus Pentax K-mount bodies like the MX or ME Super. Inspect the lens for any lateral play in the barrel, which can occur with well-used compact zooms. SDS checks the dual-ring operation for smoothness and ensures the aperture blades are clean and dry. Like many lenses of this age, we look for signs of balsam separation or haze in the rear elements. The front filter thread is 52mm; ensure this is not dented as it is quite close to the glass.
