Folks,
Just curious after doing some browsing and looking at specifications and comments. I began thinking about it after reading an offhand comment that the Fuji C series was a Celor design.
From Cameraeccentric's Goerz Catalog (1915?), the Celor is a symmetric, air-spaced double anastigmat. My questions are "How does it differ from other symmetric, air-spaced, double anastigmats like the Artar?", and "Has or does anyone else make a lens of this design?".
Now back to the Fuji (an air spaced double anastigmat) comment, there seems to be a little support for it. I've always assumed it was an Artar design, but Artars were specified at 46 degrees, while the Fuji C series is specified from 55 to 66 degrees, and the Celor was specified at 60 degrees of sharp coverage.
Cheers, Steve
