Spiratone 24mm YS Wide-Angle Lens - Front

This is a Spiratone 24mm Plura-Coat YS Wide-Angle Lens. It uses the YS mount. It's basically a reworked Sigma Multi 24mm Extreme Wide Angle YS lens (the regular style, not the filtermatic). It's a nice, straight forward and sharp wide-angle lens. The YS lets me mount it on most any camera I have.


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.
