This is a new project I'm working on, got the lens for a good (still not cheap) price.
It is a AV-Xenotar. And it looks fantastic. Nice and black. I don'nt know how the final quality will be.
I have taken the lens apart already but I can't find what type of lens it is.
For the shutter I will be using a Copal 3S. Still waiting on some parts before I get going.
Coverage will be probably around 90 to 110% of 4x5 at infinity.
The scheme on the first photo is a more correct schetch. The second photo is more to give an idea of the thickness and curve of the glass.
I think it is closer to a Sonar type lens than a Plannar (Xenotar) type lens.
Here is a website with some lens designs
I think its closest to the Zeiss Sonnar 50mm 1.5 1932.
What do you think?
