I received this 28mm Travenar lens as a Minolta MC mount, yet it is not a Minolta mount lens. The lens does not fit my Minolta X-700. The mount diameter is too wide. The standard aperture coupling pin is missing, and the pin on this lens does not rotate radially; instead, the aperture stops down when the pin is pressed in. Does anyone recognize this mount?
Update: The silver ring is removable, revealing a standard M42 screw mount. The silver ring appears to be a Minolta Maxxum adapter ring. Thanks for looking anyway :-)
