Remarks:

This Trinovid from the mid 1960s was not only an industrial design icon, it also made history because of its good optical performance in such a small size and lightweight body (you would not find many 10x40s today that weigh a mere 590 grams!). The shape of the binocular body required the use of a particularly shaped prism assembly, called Uppendahl after its inventor. In books of the 1960s and 1970s, the Trinovid was listed as one of the instruments recommended not only for daytime use, but also for hobby astronomers. It was robust and even sometimes found its way into the personal equipment of army officers. Looking at it today, the absence of phase coating on the prisms becomes painfully obvious in the lack of contrast when compared to modern 10x40s. But if you take it along nowadays on a hike, it is still quite an eye-catcher for many people.
