二手 Mamiya M645 120 底片插入式片盒背

The latch clicks shut with a reassuring solidity, and the film advance feels precise—no looseness or skipping. I’ve already run two rolls through it and the frame spacing is spot-on every time.

The dark slide slides out smoothly, and the insert fits snugly into my M645 body with zero light leaks. Loading 120 film was straightforward, and the frame counter resets perfectly every time.

The film advance mechanism is buttery smooth and the dark slide fits perfectly, no light leaks at all. Loaded my first roll of Portra and it wound evenly without any issues. For the price of a used piece, this back feels solid and ready to shoot.
