Greetings!
I have been a Lurking Member for about a year. I waited until I was a large format owner before posting.
Last Tuesday I purchased a 1953 Pacemaker Speed Graphic with a Kodak Extar 127mm f:4.7 lens and a Voigtlander Collinear II No. 4 7 7/8 in f:5.4 to 45 barrell lens. D.R.P. 88505, No. 108228, 18 blade iris.
I would like any information y'all can provide about the Voigtlander II lens. The optics are in very nice condition considering that they must be 100 years old, give or take. Is the lens useful? I did some searching here and the Collinear lenses were mentioned as being convertible. Is this true? How do you "convert" the lens? I gather it involves using either the front or rear elemts individually. What would the 7 7/8" (200mm) focal length convert to? I probably don't have enough bellows on the Speed Graphic for anything really long. I do hope that this old lens is worth using.
I'll be back with a lot more questions. It's been far too long since I had a Speed Graphic in my hands.
Thanks for your help.
