Remarks:

The Omegon 2.1×42 appears every bit identical with the Vixen SG 2.1×42 (see separate post https://binocular.ch/vixen-sg-2-1×42/) – the exact same dimensions and used materials, the same excellent finish, solid mechanics, and ease of view -, with two exceptions: the Omegon is 10 percent lighter than the Vixen, and its antireflection coatings are not of the same high quality, easily noticeable on the brighter reflections which the Omegon’s lens surfaces produce on bright light sources. The weight difference could indicate that optical glass of a different quality has been used in the Omegon than in the Vixen; this and the different AR coatings do in fact make the image in the Omegon slightly less bright than in the Vixen. Otherwise, there is no noticeable difference when observing with the two instruments. The Vixen is marked “Made in Saitama” (Japan) while the Omegon seems to be produced in China (under a licence from Vixen?).
