Yes they have a single focus knob with an added diopter adjustment. This isone of the best features of these binos. You set the binos up to match each eye one time only when you first get them. The rest of the time you use these binos the diopter stays in position and will chase the main focus knob to give you a fast focus to your target. My old pair of binos I had to adjust each eye at a time. Then I would have to readjust each eye at longer ranges vs. closer ranges. These Meopta Binos you don't have to do that. Their low light capability has been great so far as compared to my other binos as stated on page one. I'm looking forward to testing them against my Leupold Vari-XIII4.5-14 50mm scope to see what one I can see better through.

Here is their web sight:

or you can get these details off of Cabelas web sight:

From fine cars to binoculars, precision craftsmanship has been the hallmark of European manufacturing for centuries. Although this meticulous attention to detail slows the manufacturing process, it results in products with unparalleled performance and dependability. That Old World craftsmanship is the reason Cabela's recently teamed with a major European manufacturer to produce this new line of high-performance binoculars. The result of this unique partnership was precise optical clarity that can only come from high-end European glass at price that could be offered only at Cabela's. All lenses are fully multicoated using a revolutionary Ion Assisted lens coating for optimum light transmission. In addition they also incorporate half-pentagonal and Schmidt roof prisms. This combination results in brilliant color definition and crisp edge-to-edge image clarity that rivals the most elite image clarity that rivals the most elite binoculars to come out of Europe. We then housed all this optical performance in a sleek, ergonomically designed aluminum-alloy body protected by a rugged layer of rubber armor to reduce carrying weight while still keeping them fully protected from rough use. Because each pair is completely nitrogen purged and then sealed, they're guaranteed to provide a lifetime of fog proof, waterproof performance. Other features include twist-up eyecups and a convenient oversized center focus wheel with an integrated adjustable diopter for instantaneous one-handed focusing.
