I stumbled across this video on Twitter yesterday. It offers a bit of insight into the manufacture of high end binoculars and optics for birding and nature watching from the perspective of a pair of Swarovski Optik’s flagship binoculars — the EL Swarovision range.
While this is a Swarovski video, I’m sure there are parallels with all of the leading optics manufacturers like Zeiss, Leica and Nikon. Fascinating stuff… and perhaps some clue as to why the best-of-the-best cost so much.
