ROLLEIFIX Quick Shoe A quick shoe for twin-lens reflex cameras like the Rolleiflex. I used it with a 3.5F and a wide-angle Rolleiflex. I heard that attaching a tripod directly to the camera body's screw hole could, in the worst case, damage the Automat mechanism, so I always used the Rolleifix when using a tripod. I am selling it because I will not have the opportunity to mount my Rolleiflex on a tripod in the future. I have used it with care, but there are some scratches and marks from use.
