Pentax SMC Pentax-M 55mm f/1.8 - Pentax K Mount

The SMC Pentax-M 55mm f/1.8 is a standard prime lens designed for the Pentax K-mount, specifically the compact M-series cameras. It offers a slightly longer-than-standard focal length and a bright f/1.8 maximum aperture, making it effective for low-light photography and achieving a shallow depth of field. The multi-coating (SMC) helps to reduce flare and improve contrast, providing reliable performance in varied lighting conditions. Used examples should be checked for oil on the aperture blades, which can cause slow or sticky operation. The rubber focus grip should be securely attached and not showing signs of 'blooming' or loosening. SDS inspects the mount for wear and ensures the optics are clear of scratches or internal haze, which can affect the contrast and clarity of the images.
