Hello all. I am new to this forum and to LF photography. I have an S-Claron, 9/355 lens I received from an estate. In trying to research it, all I discover is G-Claron in this size. Can someone shed some light on what I have and is it the same as a G. Pictures are attached. Any info as to it's usage, history, popularity, and value would be appreciated. Thanks, John.

Seven and a half years since the last sighting of this lens:

Hmm. If it were from Zeiss, the S- prefix would stand for Spezial and the lens would have been designed for a special application. S-Biogon, S-Distagon, S-Planar, S-Tessar, mainly for use a near distances. Some S-Planars are stepper lenses for chip manufacturer, they're not all photographic objectives.

But Schneider ain't Zeiss

The middle one of a batch of 3 produced on Jan 29, 1969. I searched the lists (Hartmut Thiele's Grosses Fabrikationsbuch, S-K band II) for a few years either side and couldn't find any other reference so it was either a special order or a pre-production test run of a lens that never made it into production. There was a similar occurrence in 1971 with two examples of a 315/9 V-A Claron.

There was a batch of three 355/9 G-Clarons the day before and that seems to be the first time that particular focal length appears so maybe Schneider were trying a couple of different options and decided to stick with the G-Claron design.

Can't help but wonder if it isn't an Artar type like the Repro Claron. I'm also curious if the barrel is size 2 like the rare 355 Ronar dialyt or the more normal size 3 like the Compound shuttered 355 G's. Are the threads where the lens tightens into the barrel 50mm or 56mm?

The threads that attach the lens to the barrel are 46mm.

If you close the diaphragm, and look at reflections in the lens from a single light, what do you see?

Not sure. What am I looking for?

Jim Galli suggests the lens might be an Artar type. If so, you will see four strong images of the light. (Diaphragm closed, remember.) If like a "G" Claron, you will see only two.

Ernest, a dagor type G-Claron will have two bright and two faint reflections in each cell. Two air-glass interfaces, two glass-cement-glass. A plasmat type G-Claron will have four bright and one faint reflections. The faint reflections are often hard to see.

I see 2 sets of double images. Or, I guess, four images total.
