Asahi Pentax Auto Bellows M lens mount_Mamiya RB and includes the electrical contactsThe Asahi Pentax Auto Bellows M is a good quality macro bellows for K mount cameras. Use it for macro work, or use the included slide copier to digitize your slides and negatives (with a compatible digital camera and lens, which I feel we should mention is not included). In excellent condition overall, with minor bellows wrinkles which don't affect function. Includes double cable release.
