Hello, can anyone tell me about this brass lens, it's marked The Voigtlaender & Son Opt. Co., New York. Collinear Series III no. 8 f7.7. Aperture is a modern scale f7.7 to f64. The focal length seems to be about 18/19 inches or so. I'm wondering how this lens would compare to a 19 inch Dagor in terms of image quality, coverage, and value, they are similar in construction, symmetrical cemented triplets with different positive and negative configurations. Any other practical information would be most appreciated, is it overkill to use this lens for the 8x10 format? Many thanks.
