Junk Shop Find (Cambo, 90mm Super Angulon)

[Carography]

Thanks for the info Les. I saw lots of black cameras as well.

Can anyone tell me what Model Cambo camera this is. Id like some information so I can post it for sale.
thanks

About the schneideritis, it has no impact in the result, if very large areas had lost the paint it could generate some flare, so normally it's just a cosmetic issue. You always can disassembly the lens and painting the spots, but that's not worth technically, some may do it if wanting to sell the lens.

Schneideritis is not the only _deritis, there is Fujinonderitis, Zeissderitis and others.

In the case of Zeiss microscopes circa 1970's, their "deritis" is optical adhesive failure and more than a few Zeiss microscope optics are not edge painted to reduce internal flare.

Lens "deritis" has less impact on lens image quality than most would want to believe, it just does not appear so nice.

"Schneideritis" is flecks of the flat black anti-reflective coating that Schneider paints the insides of their lenses with. ... Double check to make sure if the specks are black paint-like material or if they look like metal.

Care to expand on that one? I have had a couple of CZJ medium format lenses that had scheideritis and indeed it is a mere cosmetic issue, easily repaired if the lens is CLA'ed. But the Zeissderitis looks less benign.

Fujinonderitis looks identical to Schneideritis complete with metallic-whitish appearing spots on the edge of the lens. This happened on some Fujinon lenses of the same vintage as Schneider lenses. There could be some commonality of edge painting materials used between Schneider-Fujinon.

Zeissderitis is bad and far more serious. This is cemented lens elements separating. It begins at the cemented lens edge and progresses to the center of the lens. This can severely degrade optical performance where both Fujinonderitis & Schneideritis more often than not does not have a significant or serious impact on overall optical performance.

As time passed, Schneider, Fujinon, Zeiss and others figured out the problem and does not occur as common as it once did back in the late 1960's to 1970's.

Have yet to have edge painting or lens cementing problems with Wild Heerbrugg, Nikon, Leica-Leitz, Olympus, Nikon microscopes.
