I have a Rollei 2.8D, and a Mamiya C330. I am having a problem with the image floating into the writing on the film. For instance (especially with Tri-X, not as bad with HP5+, but still occasionally) the exposed area is not centered on the film and is towards the edge and sometimes the writing from the manufacturer is actually a little in the frame. I have spoken with Rollei, and Mamiya and some repair people that haven't heard of this. the spacing between frames is rather normal. I am thinking that it most be user error since I have the same problem. Any suggestions/theories/WAG's would be appreciated (that stands for wild _ss guess). Cheers!
