The Nikon Superior E bincoculars come in 10X42, 8X32, and 12X50. This binocular has attracted a following of reviewers who consider it the best binocular in the world.

Although our judges found the Superior E slightly less sharp and not so close focusing as the 10X42 Premier, we still rated it the best Porro prism binocular we tested. It has good eye relief (17.4 mm).

However, it is not waterproof. Therefore we cannot recommend it. It was good enough ten years ago, but today there is no excuse for an expensive binocular not to be waterproof.

The Nikon high-end binocular we do like is the Premier LX.

For other recommended binoculars, please take a look at the Binocular Advisor.
