I recently stumbled upon a couple of lenses. Both are made by CAMBRON. One is a wide angle lens and the other is a tele lens. They both say that they are made for Minolta, Konica, and Yashica. It seems I need a screw mount adapter to fit onto my Minolta. Can anyone shed some light on these two lenses and how to use them? I've been searching all day to no avail. Any help is appreciated! I can take pics of both if anyone is interested.
