In a world that's complicated enough, these affordably priced Perma-Focus binos are a relief for simple, fixed-focus, long-distance viewing. The wider field-of-view makes them ideal for spectator sports, distant wildlife observation or winter use with gloves. Thanks to quality fully coated optics the action is bright and crisp and the ergonomic rubber housing means you won't drop them - even with those gloves on.
Specifications for this Bushnell binocular include:
- Magnification: 10x
- Objective lens: 50mm
- Field of view at 1,000 yards: 393 feet
Tech Talk Objective Lens: The diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image.
Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view.
Porro Prism System: In porro prism binoculars the objective or front lens is offset from the eyepiece. Porro prism binoculars provide greater depth perception and generally offer a wider field of view.
Owner Reviews, Ratings, Comments and Criticism
I really like the perma-focus attribute of this product. We use it for nature watching while hiking and vacationing. It's good to be able to pass the binoculars back and forth to others without losing the subject while adjusting the focus each time. Only drawback is the difficulty in holding binoculars steady when viewing due to magnification. Best binoculars we've had.
