I remember this Zeis-Novar 6.3 lens as a rather bad lens - my Lubitel
lens was better
- - my Yashicor lens was better and my current 3.5 Xenar on a 1950 Rollei
is much better.
Of course I like my old Leica and new Minolta lemses etc.
I have a good Tessar 2.8 lens on a Zeiss Tenax, but the camera is
defect.
