With it’s “EDG” series of binoculars, Nikon established itself as the maker of very fine instruments in the premium segment of compact binoculars. The 8×42 was competing head on with same size top competitors such as the Zeiss Victory SF, Swarovski EL SV or Leica Ultravid HD+. The EDG even outperformed competition when it came to things like compact build, straylight control or eyecup mechanics. Currently, it seems that Nikon no longer produces the EDG line of instruments – a pity really.
