I recently ordered a used zoom lens and I can't mount it to my camera (Pentax K1). The lens is an old Sigma APO 75-300 f4-5. It has a plastic flange (or something) extending past the mount base plate (as pictured). The plastic over-lap will not allow the lens to make full contact with the camera. I'm will likely just file the plastic down, but I thought I would consult professional advise first . Any help would be much appreciated. Thanks, Rick
