Combination Center Focus / Diopter Adjustment

For a more convenient quick focus, the 828 Swift Audubon features a center focus knob which controls the left eye diopter adjustment. To use, simply grasp the top of the center focus knob and pull up, this is is called the Diopter ring.  The diopter ring will then turn independently to adjust to the left eyepiece only.

Once you have set you diopter press down on the diopter ring to lock the diopter setting in place. When locked the center focus knob will continued to work as a complete unit.

Swift Audubon

Swift had added a roof prism version of the world famous Audubon binocular. Using the same renowned 8.5x, 44 optical formula, BaK4 prisms, twist-up eyecups, and lightweight rubber armored body. The 828 offer fully multi-coated optics for high resolution viewing, close focus to under 9ft., and comfortable 19mm eye relief. The latest models incorporate a left diopter adjustment operated from the center focus knob that makes focusing easier and faster.

  1. Very good bird watching binoculars 5 Star Review

    Posted by on 11th Nov 2010

    These are really fine glasses. They're bright, sharp with little chromatic aberration but for the very edges of the field of view. They handle well. My wife has very small hands but finds them much easier to deal with that the 7x50 porroprism binculars they replaced. Their most outstanding characteristic is, in may opinion, their long eye relief, which makes them exceptionally good for people like myself that need to wear glasses when using them.

  2. Best Binos I Own! 5 Star Review

    Posted by on 11th Nov 2010

    Although I don't own Zeiss, Leica, or other high end binoculars I do own Nikon Monarks,Leupold Katmais, and Bushnell Legends as well as Swift Eaglets and I find my Swift Audubon 8.5x44 to be the clearest and sharpest of all my binoculars.
    These binos are just great in birding and wildlife observing application and I couldn't be happier. Although a touch heavy they are well made and solid in your hands. I've already showed them to friends and have encouraged them to consider the Audubons for their next birding glass. I cannot say enough about the images they provide - bright too! Eye cups twist-up, lock-up, & STAY UP! Solid in every way!

  3. Need a nose job! 3 Star Review

    Posted by on 7th Nov 2010

    The knurled focus wheel bumps into bridge of nose. NOT at all comfortable to use like the original (now lighter weight) 8.5x44 Swift Audubon. I do NOT recommend them unless you have eyes that project well beyond the bridge! Optics fabulous, but not as good as in the original. Enough said.
