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.
