Pentax 50mm f/1.7

?The SMC Pentax-M 50mm f/1.7 is a classic manual focus prime lens renowned for its compact design and optical excellence. Introduced between 1977 and 1984, it features a 6-element, 5-group optical construction with Pentax's Super Multi-Coating (SMC) to minimize flare and enhance contrast. Weighing approximately 185g and measuring 63mm in diameter, it's a lightweight yet robust lens suitable for various photography styles, including portraits and street photography. While it delivers sharp images across the frame, stopping down from f/1.7 to f/2 significantly improves image quality, reducing softness and vignetting.

This example shows few signs of cosmetic wear and is clean optically.

It comes with the caps and a six month warranty.
