I found this Carl Zeiss Jena lens for Leica SM (M39) at a flea market. This is what I could find about it:
The Herar should be cheaper opportunity to the Carl Zeiss Biogon. It was originally produced for the Contax mount. The lens was produced around 500-1000 times. The one i found appears to be a prototype/sample for the Leica screw mount M39. It has a connection for the range finder and the aperture can be controlled with the front ring of the lens. It was produced before 1939.
I hope I got everything right.
My two questions:
Are the infos are all right (age, Version etc.)
and since inform own a Leica with drew Mount I want to sell it. What is the right price? (I only found two offers online both around 3000usd, is it really worth that much?)
I also read that one was sold at a Auction at Christies in 1992.
I’m very thankful for any held or answer ✌🏻
