Carl Zeiss Jena Tessar 10,5cm f4,5 in Compur shutter
I have a very nice example of this fine lens in a working Compur shutter.
Lens has no issues at all, and shutter fires on all speeds.
Use it for 8x10 macro or super-wide work, or find another way to use this baby.
No flange, but it's light enough that I was able to use hot glue to fix it to the lens board.
No caps, but it will be packed for protection.
Edit: I know it doesn't cover 8x10 as a wide, but I used it anyhow. I liked the black circle around the image.
As a macro it covers better, and it's fun to use that way as well.
