About this camera.
The Yashica Yashinon-DS 50mm f/1.7 in M42 screwmount — a bright, fast normal lens with Yashica's classic rendering. Important disclosure: the aperture mechanism on this unit is non-functional, meaning the lens permanently shoots wide open at f/1.7. This makes it a dedicated wide-open lens — ideal for anyone who wants that shallow-depth-of-field look and shoots on a mirrorless camera where f/1.7 is always accessible.

In short
A permanently wide-open fast fifty — perfect for intentional bokeh-heavy shooting. The fixed-aperture fault is the sole quirk, fully disclosed and reflected in this budget price. Clean glass, smooth focus, wide open always.
