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.

Roof Prism System: In roof prism binoculars the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, stream-lined shape in which the lenses and prisms are in a straight line.

5.0 out of 5 stars Perfect for back row of auditorium, January 6, 2009

Talk about a revelation: Why did nobody tell us how much a pair of good binoculars can enhance your enjoyement of concerts and shows? My wife and I warmly recommend these Bushnell 8x21s for such events. You can save money by buying cheap seats in the nosebleed section, because for approx. $20 these binocs give you an amazing close-up view. After carefully reading the online reviews of these and the Bushnell 12x25s, I couldn't decide which would be better for a recent trip to New York, and ended up buying both. My wife and I tried each and agreed these smaller, lighter ones were absolutely perfect for the back row of Carnegie Hall and a Broadway show. The 12x25s have better magnification, but your natural hand/arm shaking is also magnified. Since one can't easily take a tripod into Broadway theaters and such, the lightweight 8x21s are therefore ideal. The perfect compromise between weight and adequate magnification. We liked the handy carrying case and weren't concerned, as others were... Read more

4.0 out of 5 stars From the perspective of a beginner and amateur photographer, October 9, 2008
Amazon Verified Purchase( What's this?)
This review is from: Bushnell Powerview 8x21 Compact Folding Roof Prism Binocular (Black) (Sports)
I know very little about binoculars. I know a lot about cameras, but have never owned a pair of binocs. I wanted to buy a basic binoculars with a decent range for my photography nature trips. I wanted to survey a scene quickly with light binoculars and decided to get this one. It's cheap, had good reviews and a respectable name. Here are my views after owning it for a couple of months:

PROS:
1. Excellent value
2. Respectable name
3. Small and light
4. Good solid quality
5. Adjusting stereo vision is quick and smooth and stays in place once found
6. Comes with a nice little soft case
7. Folds up nicely

CONS:
1. Eye holes are smaller than I would like. Still see my eyelashes sometimes. This is expected of most compact binoculars.
2. Requires a decent amount of light to work. A little difficult for sunrise photography.
3. Neck string is thin and difficult to replace

Overall, this seems like a very solid... Read more

I recently purchased these binoculars and I also own another pair that I bought at a much higher price. I have to say, these are better than my $50 binocs! Great stability combines with wide viewing area and easy focus to create the best binoculars I've ever used! This is an easy purchase, a must buy!
