I have long forgotten where I bought the lens and who the manufacturer may be and was hoping for some help.
Right away some of you will notice it has the automatic aperture and some clever detectives will see that it is a KR mount and may not even want to look any further for fear of it getting stuck on your computer. I have been very lucky and can report that the lens has never become stuck on my K10 but I have thought a few times of making the modification to make that a certainty.
Does that mean that this is a Ricoh made lens? The lens is made in Korea and was purchased for my K1000 somewhere in 1984-1986.
Any help or suggestions with identifying the lens is welcomed. (Yes I will clean that fingerprint off the front before using it next.)
