I used the only stop I have for my Voigtlander. It is about F-16. The rear glass is the original and the front is a +1 diopter. Hence the Hybrid Euroscop. It is about a 16" lens.
Thanks, you guys! I am really loving this! A lens that I thought was going to be a 46" because it only had the rear element turns out to be a gem! Thanks to Jim for the suggestion on the +1 diopter. This lens is SWEET!
Miles, thanks. Not bad for a test shot to see if the new camera works and to test my cobbled together Voigtalnder. I think I hit a home run with this combo!
