jimgalli said:Funny how your lens kit gets built. And added to continually. I started out like most folks willing to pay the extra bucks for the showier lenses. Dagors whether right or wrong get valued something like this:
Kern Gold Dot MC,
Kern Gold Dot SC,
Goerz Optical Co. and American Optical Co. SC Gold Rim, or Golden,
American Optical Co. SC,
and all the rest.

PM me John when you get some negs developed, I would like to know how the lens is working out for you. I tell yah no matter how carefull I am I end up cutting at least one corner.jp80874 said:Mike,
I bought a C. P. Goertz AM. OPT. Co. Dagor 12 IN F 6.8 Gold Ring with supposedly 560mm Image Circle at the LFVC conference from Jeff at Quality Camera.. It is in an Ilex #4 shutter. I did this because I had discovered the fine art of vignetting with the 305mm G Claron in my new to me 7x17.

What differences are there in a Dagor design vs. a plasmat? Aren't both constructed along a 6 cell-4 group configuration?

Just wondering, have you ever compared the 355 G-Claron of Dagor and plasmat design to see if one offers greater coverage?

Mike A said:Jim i bought a 305 Claron from you that i use on my 11x14. The lens delivers and all but I would like to get something in the same focal length with a larger image circle. Any recomondations would be appreciated.
Ole, are you sure that you didn't describe a 6/4 double Gauss? I ask because "+ (-+)" seems to describe a meniscus in front of a cemented doublet, and plasmats are the other way 'round.Ole said:A Dagor is 6 elements in 2 groups, each group in a (+-+) order.
A Plasmat is 6 elements in 4 groups, each cell in a + (-+) order - an "airspaced Dagor".
My only Dagor is an "original" - a 1912-ish "CP Goerz Berlin Doppel Anastigmat Serie III (Dagor) 18cm f:6.8". Nice enough, but not great.

dmax said:Ole,
Thanks for the clarification. Now for another question: I have heard of Schneider Angulons being referred to as "reversed Dagors", apparently because Schneider at that time wanted to circumvent applicable design patents. What exactly does the phrase mean in terms of construction?
Hi all
Will 9-1/2 f:6.8 Goerz fit directly to any shutter? Thanks.
