I have a Zeiss Ikonta 521 and the lens has fogged between the elements. Has anyone repaired one? |

Do you mean fogged between elements or fogged between cells? Have you removed the cells and looked at them?
I've found that most (not all) fogging in old camera lenses can be removed by cleaning the outer surfaces of the cell. I use ordinary window cleaner (Windex), denatured alcohol and lacquer thinner, in order of increasing strength. Have you tried cleaning these surfaces? |

There are no cemented pairs in a Novar, so you should be able to reach all glass surfaces without much difficulty.

The front element can be removed (unscrewed) by first unscrewing the small protruding screw that act as a "bump stopper" at the infinitum position. This gives you access to the aft face of the front lens and the front face of the second lens. If the fog persists after cleaning rhese, then you should remove (unscrew) the back element,working from inside the camera (there is a clearly visible ring with two notches). It is actually easier than my description would seem to suggest. |
