What is causing the light leak in my Hasselblad A12 back?
Photography Asked on July 3, 2021
I have this consistent leak in the middle of my frames. I thought that I had at first messed up replacing the seals, but the leaks persisted after I replaced the light trap once more.
There is some damage on the edge of the back, which seems to roughly line up with the position of the leak, but not perfectly. Could this be the cause?

After finding very similar pictures of leaks online, and talking to an experienced repair guy, I found out that the leak is caused by an improperly closing auxiliary shutter.
The Hasselblad V series has two flaps on the back of the body, which need to make a proper seal together to prevent light that is coming through the viewfinder from reaching the film plane. In my body, these just don't touch perfectly snugly.

If it was leaking before you did the seals and it is always at the same spot then yes it is most likely the damaged area. If you can't seal it on the inside, tape the outside.
