One more problem I found. The rewind crank will spin on its head. I ran a roll through it this evening when there was a truely beautiful sunset. I thought I had the roll rewound but when I opened the back there was the film dying in the lamplight. I thought I had the rewind button pushed down but apparently not. After I tried the rewind button again I was able to rewind it but I dont know how much film I lost in the process =[
Is this normal?
I have noticed with my F1 that I have to keep the button firmly pressed all the way through the roll-up.
