Recently I bought a Agfa Optima 1535 -- a short base rangefinder from the late 70s. It's a nice camera but I've been getting this odd light leak on every frame.
There's a horizontal streak or pair of streaks running across the top of each frame, just a few mm down from the frame edge. The odd thing is that the door edges on this camera are quite a bit away from the film path. I just can't see how it'd be the doors leaking light that causes the problem. Also, this camera has a 'light-shield' that covers the film once it's exposed so it looks like the light leak is happening at exposure time or just before.
Any suggestions? I include one frame to show the problem.
