I recently mounted a 12-inch Goerz Dagor, Series III/ f 6.8/ No. 6 in shutter to a board I had fabricated for my Folmer/ Schwing 7x17. I am ready to go (despite needing to have my lone filmholder re-worked).
I would appreciate anyone (preferably with direct experience) giving me some feedback on the following questions I have. Many thanks!!!
1. Despite no coating on my circa 1918 specimen, is it true that the lens' simplicity of design with its fewer air to glass surfaces will still give me decent contrast?
2. Ron Wisner said the lens had around an 89-90 degree angle of view. That seems a bit tight for the 19-inch diagonal of the 7x17 format. Will stopping down to around, say, f 22, give me a decent amount of useable image area, let me avoid vignetting, and give me some wiggle room?
3. I am aware that this particular lens is commonly used on this format. But what might be another step up in similar focal length? What about a 305 G-Claron? Differences, simularities?
Would the longer 355 Claron necessarily be a whole lot better by virtue of it's increased coverage? I know this is subjective, but I'm curious about other's preferences and why.
I know I need to field test myself. But I like to get it in the head first. Sorry.
Many Thanks In Advance Amigos,
