This is a Spiratone 28mm YS Wide-Angle Lens. It uses the YS mount. It's basically a reworked Sigma Multi 28mm YS lens. It's a nice, straight forward and sharp wide-angle lens.
The YS mount is basically an auto diaphragm T-mount system. It utilizes the same dimensions and thread pitch as a T-mount. The point of the YS system was to have an auto lens that could be used on any auto camera with the correct YS adapter, while allowing the retention of that camera's auto diaphragm system.
