Remarks:

First introduced in 1957, Zeiss (Oberkochen, West Germany) soon named this 10×50 classic porro binocular “Jahrhundertglas” because of its rare combination of compact size and very wide field of view, compared to other 10×50 instruments. The sample presented here was made around 1970 (serial number: 817169). Tele-objectives with a wide air space gave it the wide field of view, while “Astroplanar” five lens eyepieces allowed for an amazingly good edge sharpness.
