Film windon perceived as problem of RF645 by some...
Issues related to frame spacing, film bunching and film jamming on the windup spool are occasionally mentioned with regard to RF645 Bronica's, and often in error. It is more often user error in film loading.
It is consistent with all 120 roll film cameras that transport the film horizontally and are loaded in spools at each end of the film frame, that film will be loaded loosely and not held tight during closing of the door. This is true of the Fuji Rangefinders, Pentax 6X7, and the Bronica RangeFinder, among others.
The 120 SLR cameras that load on inserts have the film tight when inserted in the film back.
I've used a number of horizontal transport cameras, and found that the film needs to be on the start line and held snug with the windon lever as the door is closed.
So, before attempting to blame these types of problems on the camera, test your film loading technique.
I do know in the case of the Fuji Rangefinders, making sure to load film tightly is dealt with in the user manual for many years of production on the 645 and 690 models.
I,m not sure if Bronica ever figured out how poorly many users handle 120 roll film, and mentioned it in the manual. I do know that there have been complaints of frame spacing and jamming issues on Bronica RF645 posted on the internet, and corrected by developinga better loading technique.
