Hello, I have just purchased a Zeiss Nettar. Could anyone tell me if the camera should have light seal's? Only I can't see any evidence of previous seal's. I took the camera out today and used a roll of HP5, got home and developed the roll. Only to find every frame had a tiny leak on the bottom left of every neg. I've checked the bellows and they are clear of any leaks. So... I can only assume that the door has a leak??? Can anyone enlighten me as to IF the camera has or should have light seal's In the door. Cheers Kit.

Closest thing I have is an Ercona II (post-WWII East German Zeiss). That does not appear to have seals, just a sort of "labyrinth" around the door.

Light leaks can definitely be a pain. Remember that the image is upside down on the film when looking for a spot. It's also wise to look at whether the leak, as seen on the negative, extends outside the image, portion, perhaps to the edge of the film, as opposed to stopping at the image edge. The latter would likely indicate the leak is somewhere in the bellows or at least ahead of the film mask. Leaks to the film edge tend to be caused by light striking the film between the supply or take-up spool and the film gate/mask area. I've had that with the film backs on my Bronica SLR.

Good luck!

Like Dave, most of the older folders I am familiar with didn't use seals. Sometimes the edges of the back get bent or the back is distorted. There might also be debris of some sort in the channel the back's edge fits into that keeps it from seating fully.
