About This Lens The SMC Pentax-M 50mm F1.7 is one of the most refined standard lenses ever produced by Asahi Optical Co. The "M" series was introduced in 1977 as a slimmer, lighter evolution of the original SMC Pentax K-series — designed for the compact Pentax MX and ME bodies. Despite its small size, the optical quality is outstanding, delivering sharp, contrasty images with smooth, natural bokeh. This lens has gained a devoted following worldwide among mirrorless shooters who appreciate its compact form and exceptional rendering. With a K-to-E mount adapter, it pairs perfectly with Sony mirrorless cameras. Condition: [ Near Mint ] Appearance: Beautiful condition, almost no signs of use. Please check photos for details.
