Birders have a lot of choices for binoculars today. Picking the best is not an easy task. And much of what you like or dislike about binoculars can be intensely personal, or even based upon what you've used in the past. But the consensus best binos for birders today are the Leica Ultravids 8x42 or these, the 10x42s. By the tiniest fraction, I come down on the side of the 10x42s, although perhaps not for beginning birders.
There is no substitute or trying binos before you buy. As I said, this is an intensely personal choice. But a couple of features make these especially attractive: the 42mm objective lenses let in a lot of light, making these especially good in low light. The focus is tight; you don't have to crank the knob multiple times to get crisp focus. They fit my hands well, and are exceptionally light weight for armored, powerful glass. And the color quality, critically important to any serious birder, is outstanding. The single drawback to the 10x42s is that the narrower viewing field with the greater magnification requires you to know where the bird is. The 8x42s, with their larger field of view, make it easier to find the bird. Which is why the 10x42s might be preferable for experienced birders.
For years I used an excellent set of Zeiss 8x42s, state of the art in their day. The lighter, brighter, color-corrected Ultravids are state of the art today. Very highly recommended.
