二手 Mamiya RB67 雙重底片夾 J

Picked one up for my RB67 kit and the film advance feels just as smooth as my newer holder, even with the scuffs. The dark slide glides nicely, and it holds the film flat without any light leaks.

The scuffs on the body are exactly as described, but the double cut mechanism slots in and locks tight with zero play. I've run a few test rolls through it and the film positioning is dead-on every time, no light leaks at all.

The film advance is smooth and the dark slide fits snugly, no light leaks to worry about. A few scuffs from use, but the internal mechanics feel tight and reliable.
