Dry firing with the back off it performs perfectly, first maybe 5 or so shots off the roll it performs perfectly.
As you go through the roll it seems to struggle progressively more and more to wind the film, until the last few shots it can't even manage to wind a single frame and you have to flick it off and on again to coax it through bit by bit.
It does the same no matter what film you use, and it is the original factory 120 back with 120 film.
I sacrificed an old film, loaded it into the camera and wound it through manually, I found there is quite a lot of resistance, and the further through the roll you get, the tighter the film and more resistance there is, until eventually it is difficult to wind the film manually towards the end of the roll.
Pretty sure it is an issue with the holder and something is not as free as it should be. The end spool (with the big metal cog) seems to spin relatively freely. The start spool is quite stiff and tight to turn and there is some resistance. I undid the 3 tiny screws to take off the plate at the side of the film holder to see if there was anything obvious under it but there isn't and everything looks like I guess it should.
Anyone else had this issue?
Could anyone check for me to see how much resistance there is turning the film on the first spool?
Could it be the way I am loading the film (pretty sure I am loading properly though)
