Looking for a new lens to replace my Industar-13 300/4.5 on my 8*10" (actually 18*24cm) Russian FKD camera I was proposed to buy the old brass lens on the lensboard with no shutter and with the following sign on the front rim:
C P GOERZ BERLIN № 196615 DOPP-ANASTIGMAT Serie III DAGOR, F=300mm, 1:6,8 (see the attached picture).
As I knew Dagors are good performers, but I didn't try one by myself yet. So, I'd like to ask someone who have (or did have) this lens or someone who knows a lot about Dagors to give their advices about the suitability of lens for my tasks. The nuance is that I'm going to use this lens on the wetplate camera and I intend to use it mostly for the portraits.
Is this Dagor the right (or suitable) choice for this kind of photography or I should find other lenses? I know that there are much more suitable portrait lenses for wetplate (e.g. famous Dallmeyer 3D, or Rapid Rectilinears, special Portraits, etc.), but let's make the decision about this Dagor.
And... is $180 a fair price for this lens?
BTW, I know that the best way to decide whether to buy lens or not is to shoot with it, but the seller lives about 2500 miles away from me, so this way will be a bit difficult.
