Vintage binoculars - Nippon Coated Optics 7 x 35 Wide angle field 10 degrees

Nippon Coated Optics was a Japanese optical company that produced binoculars primarily from the 1950s through the 1980s. The "Nippon" marking indicates Japanese manufacture, and "coated optics" refers to anti-reflective lens coatings that were becoming standard during this era to improve light transmission and image quality.

The 7x35 specifications indicate:

• 7x magnification - objects appear 7 times closer
• 35mm objective lenses - the diameter of the front lenses
• 10-degree field of view - this is quite wide for vintage binoculars, giving you a broad viewing area

These binoculars would have been considered mid-range consumer optics of their time. Japanese optical companies during this period were building a reputation for quality that would later make brands like Nikon and Canon world-renowned.

For collectors, Nippon Coated Optics binoculars are generally considered decent vintage optics.
