It's Chinese 56mm binoculars that first changed the point of views on Chinese optics industry held by the users in North America and European countries 4 or 5 years ago. Before 56mm, Chinese binoculars were considered to be "the cheap" sold in "dime-stores". After 56mm, the users agreed that Chinese manufacturers could make some good enough binoculars.

Though the product lines have been expanded since the last 4 or 5 years for Chinese optics industry - bigger and more specialized binoculars made, 56mm binoculars are still in great demand today.

All the Chinese 56mm binoculars come with Bak-4 prism, broadband multi-coating on the objectives, rubberized metal bodies, all-glass lenses, right ocular diopter adjustment, brass 1/4-20 tripod adapter threading, case, caps, and strap.
