I picked up this Zenit EM the other day; I paid £1 for it at a carboot. It was thrown in a suitcase with a bunch of junk; I had to buy the case to buy the camera. Unfortunately this meant I didn’t have the opportunity to check it before bringing it home.

Pleasant surprise, it still fires. The body despite being a little dusty seems well looked after, so I mean £1 well spent. That said, when I look through the viewfinder there is a big brown/yellow streak running straight down the center; I have no idea what this is.

If it’s possible I’d like to clean it up/fix it; I mean if I mess up, there’s nothing lost really, as far as I can tell the camera is 10 a penny and I didn’t pay much for it. I’m looking for someone with a little more knowledge to tell me what the line is/might be and then help me find the resources I need to fix it.

Thanks

p.s. if the picture isn’t clear enough or more info is needed I can supply new pictures.

Also if fixing the camera is going to cost more than the price I paid for the camera, let me know. Likewise if the ‘damage’ is just cosmetic and won’t affect photo quality, let me know as well.
