Yeah, Gerogons and their private-label reincarnations, were cheap lenses for compact stat cameras.

Maybe a single element achromat lens instead of a highly corrected process lens would do good. Many of these long focal length process lenses have been taken up by ULF folks paying !$! for them. Single element achromat could be found at modest cost at various optics surplus or hobby astronomy want-ads.

Yes, I learned that time ago in your article http://www.galerie-photo.com/apo-pro...ikkors-en.html
I ordered Goerz 30 inch F12.5 Apochromat Artar for my project. The main influence was weight and tiny bit shorter focal length. With both combined I could even hope to use this lens on my 11x14 for landscape photography (camera extends about 77 cm).
