Hi John:
         Prochnow explains the reasons to eliminate the GX TLR automatic film 
feeler mechanism to start the counter in the Report IV, he was Rollei cameras 
designer chief (or similar) by that time, he did not participate in the GX 
development directly but he checked the prototypes. One of the resons was 
identical regarding the SL66, film manufacture differences, the other reason 
was that Rollei knew several pro photographers forgot to pass the film between 
the rollers to activate the counter and then Rollei decided to eliminate the 
mechanism.
Anyway I have used any kind of film with the 2.8C, 3.5E and the 3.5F and never 
had a problem with the film feeler mechanism, only once the problem was for a 
very thin Fuji paper and an Agfa spool that couldn't hold the paper according 
the way I load the camera, but it had nothing to do with the film feeler 
mechanism, however I know other users had problems, perhaps due to the rollers 
adjustment.-
