    Exclamation 16" Vitax Front Elements Rochester No.5

    Hello, I have a question on the front elements of 16'' Wollensak Vitax Rochester No.5 lens. I see a small fungus growing in between the two front elements (not cemented), I have taken a lens apart near the diaphragm for cleaning but not the front elemets, does anyone know if the front portion of the lens can be unscrewed or taken apart? Since I live in a country side of Japan, it will cost me quite a bit to send this cannon outside of japan to have it cleaned by an expert. If you have any experience with it, I'd appreciate your advice, Thanks. KARU

    The front group should be a glued achromatic pair. You may have the your cell placement wrong but for the life of me I don't know how you could do that w/ the Vitax.

    Yes, Louis is right. The front group is an achromatic doublet that is glued together with balsam cement. You may be seeing some seperation and thinking the yellowish crazing is fungus. A picture would help if you have one. Easy to remove the entire front group and mail it alone if you had to.
