Combining forward, advance, and precision dial adjustment with a shutter quick release, the Film Carrier 35MD allows you to step between frames automatically with the push of a button. Once the first frame is centered using the dial, pressing the center button triggers any camera attached via the included 2.5mm shutter cable or via the included USB-C/A adapter. After your camera is triggered, the motor drive then advances to the next frame, ready for you to capture the next image.
