Found at an auction Vivitar Series 1 70-210 mm 1:3.5 lens in a carrying case, The lens is flat out mint. Pay $12.00 for it (that is with auction cut, sale tax.) Got the lens home found out that the lens will only fit a Konica camera, which I do not have. How much a problem to have the back of the camera change to fit a Canon AE-1 body or a Nikon F body. If it can't be done, I just get a Konica's camera.
Not worth having the mount changed. They were nice lenses back in the day but not as much now. The best way to use it now is to get a mirrorless camera and an adapter. Konica never had an AF mount thus the only Konica camera that it would fit would be an older film camera. I have the same lens in a Nikon Pre-Ai mount. It sits collecting dust. I see where you referenced using it on older Canon & Nikon film bodies. Still not worth it. Look for a functional Konica T-3 ( I have one) as that was one of the better Konicas. Pretty sure the serial number starts with 22. That signifies it was made by Kino Precision for the Vivitar company (Vivitar was just a marketer). Kino was a well respected 3rd party brand who's demise came after autofocus came to market. Today Vivitar is owned by Samyang, IIRC, and is not of the same quality it used to be in the 70's and 80's.
