OK I dont get how the Rolleinar's work. They came with my new camera.
Maybe I'm missing some parts.
I have two Rolleinar 2's.
One is very flat.. regular filter size. Has a small black dot on the bayonette size. It fits both the top and bottom lenses of the Rollei. When I put it on the top lens it allows me to focus at about 2 feet.
The second one is not so flat... like a fat filter. It has a red dot on the front face. The mount side has an area that has a flat cut out portion to it. When I put it on the viewing lens it allows me to get very close.. less than a foot.
Am I missing some piece to make this work....
