Hi all,

I purchased a Zenit E due to the rainy weeks as I wanted to take photos no matter what. It came with an Industar 50-2. Both are in mint condition, even the light meter works.
I ran through two rolls and after developing them I realized these black marks on the negs.
After I developed the first roll I thought that it was the developing process but as the second roll looked exactly the same I got to the conclusion that it must be light leaks.
I’ve checked the curtains against a torch in pitch black from where the lens is and cocked the shutter to check if there’s any leaks where the two curtain meet but no.
The other odd thing is that it’s not on all frames and on some it’s more present that on the other.
Where else can light enter?
I’m thinking about the side where the door is attached to the body but the foam’s condition looks great, though it can happen that despite this it lets the light in.
But then it should be on different areas on the neg not exactly on the same area.
Can it happen that the lens leaks? Is it even possible? It’s also in great condition though while focusing at some point it becomes a tiny bit looser than otherwise.
I attached a few photos of the negs.
It’s such a nice piece of kit (and I can use it in the rain without worrying too much) and would be a shame to sell it as a donor (I don’t want to do that).

The fact the light leak is on the film edge & sprocket area would mean that it's not the shutter curtain.
From what I can see of the negative, the light leak appears to be coming from the top on the neg.
Could the film door be strained and so not fully closed in the middle area or hinge (not at the catch)?
Since the leak is intermittent, could it be only in bright light?
Sorry, I can't be more helpful but I am sure someone will be better.

From the top of the negative means from the bottom side of the camera. The oblique direction then was what made Shutterfinger above hint at the lower edge of the door hinge.


At very first sight I even thought in a very different direction, namely X-ray scanner exposure. But the OP made no reference to a travel, and at enlarging the images the lines did not show a complete, sharp edge banding, but a density fall-off. Thus I came to the same conclusion a above.

Thanks to all of you!
I so thoroughly checked the door and everything and all is so tight and perfect (at least it looks and feels). Even if I push the door it doesn’t respond because it’s just so perfectly closed.
I think I might black tape the door everywhere where light can sneak in and will run through another roll and will see.
The funny thing is that a roll of Ilford almost costs the same like the camera with the lens.

Next time try to buy a camera with still unexposed film in it and make a bargain...

Yea, that’d be the right decision to get one which is film tested and works properly but as I was on a holiday and it was raining for days I decided to get a camera with a lens which I can use it in the rain. After all it was a lot of fun even if I had to face with this.

A camera being still loaded with film means no guarantee that it is working properly. Sad enough. But at best you get a free film.

maybe You can rig up something containing a bright white diode and a 3V battery and place it inside the camera.Then in a darkened room, the leak should reveal itself? I did that with MF and LF cameras which have more room inside of course; but, it worked a charm.

Yes, I’ve done this with LF obscuras. It worked and I could solve the issue.
In this case though I already decided to black tape the door hinge and everywhere where light can leak. It’s a rain camera anyway... :smile:

You only need to put very short strips of film into the camera. One with the camera as it is, the other with just that corner patched. In both cases put strong light on the camera. Develop both in the dark in a tray and see for such fogging. Or put such strip in addition to a regular film top be processed outside of a reel.
