A friend here in Adealide has given me on loan a a Carl Zeiss Jena Protarlinse in a compound shutter.
It doesn't have an aperture scale as such only a scale that I assume is the mm opening size of the iris. This I assume when divided into the focal length of the lens group gives a working apeture.
The two element groupings are a 35cm and a 48cm.
I know nothing about this lens but the glass is in amazingly beautiful condition and the shutter works.
I haven't made a lens board for the lens as yet, that is tomorrows project but with both lens groups fitted to the shutter it aeems to be a shorter focal length than the 35cm ???? If it is does anyone have an idea what ength it may be?
Any information on the lens would be appreciated.
