I just bought a Mamiya C220 TLR. While shooting a test roll, the film advance crank would keep winding quite a ways further than necessary before stopping. When I processed the roll, only the first 3 exposures were on the roll, each separrated by several unexposed frames.
This is my first 120 camera, and am wondering if possibly I loaded the film improperly (?), or if there's a problem with the stopping mechanism.
Any thoughts? |

On certain 6x6 cameras you have to follow a strict loading procedure, otherwise frame spacing will be a problem. I last used a C220 in anger many years ago; I cannot remember taking anything but the usual precautions when loading (keeping film tight), unlike my present Pentacon Six cameras.
Use a roll as a test film, mark the position of the individual frames with a pencil through the front of camera. As stated I cannot remember what, if anything, the manual said about loading. It does seem that a service is called for.
Sorry I cannot be more specific. |

This may be a long shot, but are you sure that you have the pressure plate set for 120 rather than 220? |

Thanks for input...
OK, the presure plate is definately set for 120.
Here's what I've got on my test roll: Using a good 120 negative as a spacing guide, there's 3 blank exposures, then a good one, followed by 2 blank exposures, then a good one, then 5-and-a-half blank, then one last good exposure.
This is all I got. I kept shooting until the counter said 12, but only got these first 3. I guess I had no way of knowing that the roll was finished and I was shgooting the last 9 shots onto the pressure plate, sans film.
It seems to me that the camera is letting me wind the crank much further than it needs to go with each actuation. What do you think? |

I stand by my original assessment that the body needs a CLA. You can try and get hold of the repair manual to see exactly what needs to be done, this should give you an indication if it is an easy DIY job. The problem could be caused by wear and tear, broken parts or just dirt and lack of lube. Until the internals are examined, all the discussion in the world will not really help you.
You should also replace any foam seals that are not in good condition. |

Thanks, Glenn. The camera has definately been heavily used, and I'm sure a CLA is in order. I'm off to find a manual and see what I'm getting into.
Thanks. |

If the C220 behaves like the c330, the problem is probably caused by the shutter release sticking, i.e. not returning before you wind the film. When the release is depressed, you can wind the film right to the end (the camera is designed that way). If so, a simple cleaning and lubrication of the mechanism will help. |
