Mamiya Cable Release Adapter for Shift LensThis little cable release adapter is designed to fit the Mamiya RZ67 or 645 Pro cameras, letting you use a standard cable release without interfering with the movements of the RZ's 75mm or the 645's 50mm shift lenses. Basically, it's a cantilevered 180 degree adapter for the cable release button, so you can attach the cable release from the back instead of the front. In excellent condition.
