Carl Zeiss Jena Biometar 80mm f2.8 M42 Lens Review

Very rare lens not showing up more than 1x a year on Ebay. Very well built quality lens. Ideal for portraits and artistic photographs it has exceptional good out focus background effect "bokeh". Produced around 1950-60 in limited quantity I saw with M42 and with Exakta mount. The 2,8/80 Biometar was developed in 1948. Mounted for Kine Exakta, then Contax (M42) and Rolleiflex.

Also made in Praktina breech mount, probably in reasonably small volumes. I have one, aluminium, manual stop down, with pre-set ring. Pretty thing it is, too, like so many CZJ alloy lenses.

Excellent glass. Can be found in numerous incarnations for MF, where it is used as a normal lens, on Pentacon's Six mount. A Zeiss design, the latest version the rubber one, build by Schneider-Kreuznach, optically identical with the original CZJ.

Could be the same lens for Pentagon Six with different mount.
