2 Sets 135 35mm to 120 35mm Cassette Accessories 135 Film Cartridge Adapter Canister Converter Panorama Like Xpan Camera for Pentax, Rolleiflex Mamiya Hasselblad Makina Bronica Medium Format Camera

These are excellent quality and work flawlessly. I will admit I was a little hesitant at first cause I figured I would receive some cheap 3-D printed stuff like I had in the past but no, these are amazing off the assembly line, durable, reliable adapter caps.

Exactly what I needed. Thanks

Have had zero luck getting these to work.

These adapters do not fit the Mamiya 120 or 220 film holders. The openings in the adapters are too small for the carriers. Additionally they are too thick even after enlarging the holes to allow them to fit in the Mamiya holders.

Bottom line, when attached to the 35mm cartridge, it is 1.0mm to 1.5mm shorter in height than a normal 120 film spool so you end up sometimes with the back skipping and not forwarding the film properly. I didn't mind the tight/loose fitting the seller explained in his ad description, that was a non issue as you can still apply force to remove the 3d printed converters from the 35mm cartridge but, being shorter than a 120 film spool is a deal breaker that makes this contraption completely useless!

I have a Mamiya RB67 and the adaptors are too bulky to fit into the camera back. Should have read through more of the reviews before buying. Seem like the sent me 4 of the exact same pieces so one sits too high above the cartridge to fit.
