Dagors are known for having a wonderful glow to their images and their wide coverage. They are quite a bit more expensive than the 300mm Schneider though and in most cases lack the coatings of a current Schneider.

My shooting partner is a very happy 8x10 Deardorff shooter. He is a much younger man and can lift all that mahogany better than I.

I will have to look for ‘book "Studio" Paolo Roversi’. Thank you for the idea.


Ouch. Abebooks shows the book for $400-$1200. I may just have to look at his images on-line. That is too close to the price of a lens.
