After starting out my "follow the 16mm dream" journey with a Arri Sr2 one and a half year ago I've now reached the wonderful position to own both a Aaton A-Minima and an Arri 416! Now nothing can stop me spending (loosing) money on personal projects that will go on forever… but every roll is a joy and a great learning experience!
Today I encountered a problem with one of the magazines (or with my loading of it maybe?). The film was taken up unevenly and eventually started scratching the sides of the take-up chamber. It made a noise that was quite unusual for the normally super quiet camera. When looking (feeling) for the problem in the changing bag I noticed that the film was cone/wave-like. I tried to even out the film and loaded the mag on the camera once again. After some meters of shooting the sound came back and I unloaded the exposed film. I evened the roll again when putting it in the can. Maybe that will cause scratches on the film?
It's only the fourth time I load these magazines so I may have done something wrong that didn't create enough tension. One thing I've noticed is the the lay-on roller arm isn't touching the film and core straight away. There's a small screw that keeps it from coming all the way down. After some more film has rolled up on the core it does engage (or how to explain it). This screw functions like this on all my three mags, and from what I can tell from videos and pictures online this is the way it should be, so not sure if that could cause the problem.
The film I used is a expired Fuji Eterna 400T that has been in the fridge at my local lab before I got it. It did feel a bit loose when I loaded the feed side also, can this have anything to do with it's age?
I'll keep testing to find out more, but I only brought this mag with me now, so can't compare and test the other mags yet.
Anyone who can think of a logical explanation and a solution?
