Kuzano,
The 90 f8 Geronar looks like an interesting option. How much larger and heavier is it compared to the suggested 90 f6.8 Angulon?
The Geronar is minimally larger than the Schneider Angulon. The glass however is bigger, likely for a better optical performance result. I'd say it sticks out from the more than the Angulon/Synchro Compur shutter less than 1/4 inch more in front. It is a contemporary lens, and considering what's happening to the Angulon prices (partly as a result for now of this project) can likely be purchase for little more.
The back of the Geronar is likely not protruding into the camera more than the Schneider. I believe a goal of the design was to create a lens that could readily be folded into a field camera without removing from the front standard. So in this case not much bigger. Weight... hmmm. It certainly will not make the travelwide more front heavy than those planning to use Super Angulons or similar Rodenstocks with larger optic front/rear cells.
I doubt the weight would be more than marginal and not objectionable for the improved image quality and much newer optics and shutter when compared to the Schneider Angulon in Linhof or Compur shutter.
I've held both lenses at different times, and calculate them to be very similar in these aspects. Your findings may be subjectively different than mine.
I have the Angulon 90, but I will likely purchase a Geronar 90 for this project.
I located an ebay listing that has a profile view of the Geronar in a Copal 1 shutter. This listing also has all the specs you asked about. However, this listing is one of higher priced that I see for this lens. You can do better. This listing is merely to answer your questions. Also, Geronars seem plentiful. They were sold in great numbers as teaching lens AND also come in Calumet Branding as a Caltar, often for less money used simply due to brand recognition. Rarely are branded lenses "seconds" as many people assume. I would not recoil from a Rodenstock branded Caltar any more than from the Rodenstock itself.
However, if you have a Caltar, and you go to the country club bar, you may have to sit at the bar instead of at the tables with the big boys.
Don't worry about buying the Rodenstock I showed you from under me. It's a bit pricey and there will be a ton more pass through eBay before my Travelwides arrive.
