Recently, just by chance, I ran across several lenses labeled "Kinor". Since I have a Kinon 35mm camera, my first thought was it was made for that camera -- and it will fit because it has the same lenses mount, a Minolta Rokkor MC/MD mount. That tells me that this lens was not made by the old Kinor movie lens maker. I can't find anything on this FORUM, and very little on the WEB, except that there must have been many sold under the Kinor labels. I've seen 24mm, 28mm, 135mm, 70-150mm, and 80-200mm -- all with the same, unusual, rubber controls. Below are the 24mm and 80-200mm zoom. The lenses were made in different lens mounts such as Minolta, Pentax & Canon -- all manual focus.
My Kinon 35mm SLR was made by Seagull, so I'm thinking that these lenses might have been made by Seagull as well.
Any speculation is welcome.
