Please note, all cameras shipping with the upgraded film back have had the film direction change (just follow the arrows on the film back for the proper direction of film travel) this was done primarily so the film numbers show right side up.

Additionally, dependiong on your film stock, when winding the last few frames and the end of the film leader, the winder may feel quite tight, this is normal, you can rotate the opposite nob slightly to loosen the film and aid in winding the film on, this is by design to make sure the film is wound tight, no loose rolls.
