Loading A Mamiya 6x8 Film Back

Tools Needed:


Mamyia 67 Pro S
Mamiya RB67 Pro-S

With a Canon 1Ds opening a whole new realm in photography, film recorders suddenly seem exciting again. Or maybe you just stepped up to a medium format camera for the first time and need to learn how to load the 6x7 back for it. No matter what the case may be, all Mamiya 6x9 cameras load in roughly the same fashion. Start by locating and pulling the back cover latches highlighted below. Some cassette have just one but many of the Mamiyas have two as shown in this example.

With the latches released you can swing open the back cover of the cassette and remove the film insert from the inside. Close the back of the camera and turn your attention to the insert you just removed.

You now need to move the spool from the last roll of film to the right side of the back. This is done in one of two ways:
The Mamiya RB67 has piviots on the bottom of the spool that allow it to swing out and fall free from the top spool stud. The Mamiya RB67 Pro-S cameras have a spool release pin right next to each pin. Push down the release pin and the spool can swing out at the bottom and fall free from the camera. Install the spool in reverse order and you are ready to start loading your film.

Open the film box and remove the roll from the protective foil. Now remove the paper band and install the fresh roll of film on the left side in the same way you installed the empty spool on the right side. Gently pull out ~75mm of film and loop it around the front of the camera and back to the take up spool on the right. Secure the film the same as you would any other camera by inserting the tapered end of the film into the take up spool slot and advancing the roll a few turns. Keep advancing the roll until the arrows on the new roll of film line up with the start mark arrow on the bottom of the film insert by the base of the film spool.

Now place the insert back into the outer cassette of the camera or film recorder and latch the back shut. Using the film wind lever advance the film until the number one appears in the sight glass on the top.

Building film profile

The final step is to put the films box top in the memo holder on the back of the camera, or the modern day equivalent, set the film recorder for the film profile you are using. Congratulations on loading your first medium format camera back.
