Hello, I have a Kiron lens, 28-210 mm f/4-5.6. It has a Three (3) hole mount on the lens to camera ring, but I'm not sure for what camera. Anyway I need a mounting ring to put on the lens to mount It to my Nikon D5000. Thanks, Steve ?
Sorry, but I have no experience with Kiron lenses. I have used the adapter for older Pentax threaded mount lenses, which allowed me to use lenses from my old film cameras. One problem that I did run into (and I suspect will translate to other lenses of this type) is that the lenses will not focus to infinity. OK for close work, but not for distance.
