The “Super”- Nobilem 8×50 was only produced between 1980 and 1985; the sample in this collection is from 1981. Carl Zeiss Jena tried to outperform the western Zeiss Oberkochen with the massive field of view of 140m. The drawback: the prisms had to be made so big that people with regular size hands can barely reach the central focusing knob without taking one hand off the binocular. On the plus side, minimal vignetting and good illumination of almost the entire field of view are still appreciated nowadays when panning the night sky.
