Why LAS Likes the Zeiss SFL 12x50 Binoculars:

What more could we say about these? Right off the bat they have a great, ergonomic hand feel - so their focus on that in their marketing was right on the money. In addition to the general feel of these binos, they pretty much blow the competition out of the water as far as specs are concerned, too. You're getting a brighter, clearer, wider picture in a smaller, lighter, and more comfortable package when compared to competitors. The sleeper pick for it's greatest feature, though, might be how comfortable they are to look through. The exit pupils are much larger than what you'd normally see on binos this size, and that only makes the user experience all the more satisfying. On top of all this, these are Zeiss Binoculars, so you know you're getting industry leading technology and reliability to boot. The included tripod mount, case, and other accessories really round out the deal.
