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.

Great for the Money4
This is the first Binoc purchase I have made and I will say I am quite pleased.

I have some outdoor friends that have those higher end models made from camera companies that are a few hundred dollars and in all honesty, I can't tell much of a difference. Just remember, this is coming from a beginner. Obviously experts will point out of the "niddy griddy" flaws, etc. for one reason or other. I do the same in other fields of my expertises. But unlike the typical expert, I throw away my pride and firmly believe in the most bang for your buck.

And these Binocs definitely pull through.

Would have been five stars, but I agree with everyone else; the strap is a piece of crap. Haven't even bothered putting in on.

P.S. remember that these magnify 20x. The average person will find it hard to keep the magnified image stable. Military uses 6-8x binocs for this reason.
Great Fixed Power Binoculars!!!5
Greetings,
These binoculars focus great from up-close to far away. The PowerView Zip Focus works great for fast focusing and the views are sharp. This is a great deal for the money. Always set the Bino's on a stationary surface when setting the diopter for matching your eyes the first time. Focus left eye first with PowerZoom focus with right eye shut, then open right eye and close left and adjust the diopter (twist right eyepiece) for right eye focus. Once set, you will experience great performance from your Bushnell Bino's!!!! Enjoy! ...Jamie
Decent optics but focuser is sloppy3
Purchased the 16x50 version of these Bushnell binoculars (primarily for star gazing). While the optics seem fine (for the money) the rocker style focuser is easily jarred out of position, even simply by pressing the eyepieces to your eyes when gazing upward or by trying to adjust the diopter.

Probably good for terrestrial use but be prepared to wrestle with the focus when gazing skyward.
