This suggests that the only parameters left of possible concern would be differences in plate spring tension affecting winding force, or plate surface treatment changes to avoid scratching the naked 220 film. now all of you will run to get those cheap 220 inserts. Put a roll of 220 in a 120 back and the pictures will be fine except the camera wiil rewind half way through the roll. I do not expect a problem with the film pressure plate is this has a lot of space to move (much more than the one in my Roilleiflex T) What remains to be checked is simply to shoot a film or two in this settings and see that everything is OK. So - it seems that with the teeth pointing towards the film the camera (or towards the shutter when the magazine is mounted on the camera) expects 120 film. After that the camera wounds the rest of the film onto the reel and showed "End" on the display. Loaded another film and shot exactly 16 frames. Then the camera did a short winding attempt and showed "E" on the display, which I guess stands for Error.Ģ) Unscrewing the 2 small screws I turned the plastic "thing" such that the teeth was pointing towards the film plane. So - to find out how this should work I used 2 films to figure out (one would have been enough though)ġ) with the "thing" in its original position (t eeth pointing away from the film plane) I loaded one 120 film in the back and shot 20 exposures until the film went completely through the camera. When I have bought the camera with the 220 magazine, the teeth was pointing towards the back of the camera (away from film plane) and was easy to overlook. One of these screws is slightly obscured by the steel teeth that holds the film insert attached to the camera. This little "thing" is attached by two small screws.
On one of the long sides it has a small teeth. So - when one takes out the back and looks between the latches that can be flipped out to load/remove the film spools - there is a little black plastic rectangular of size about 12 x 4 mm. In the second link you have provided is a detailed description, but let me put my version here (I checked it twice!): I am and experimental physicist - I had to try.
