This is a small post about another new (for me) lens in the camerabag – the East-German exakta mount (exa) Carl Zeiss Jena Biometar 80mm F/2.8. I regard Biometar as sibling of the legendary Biotar 75mm F/1.5.
My copy of the lens is the latest (third) version of the biometar, with six aperture blades and marked as Bm 80mm 1:2.8 “aus Jena” on the front ring.
The lens feels quite light, weighting only 295 g (for example compared to Zeiss Planar 85mm F/1.4 ZF.2, which is 570 g).
Two quick snaps of the local model, lens wide open at F/2.8.
