photo binoculars fundamentals

As it is with binoculars, so it is with scopes. Although there are many other specifications and qualities which determine the usefulness of binoculars, we will discuss in this article the primary characteristics for determining the best fit for your application.

This Leupold 10x50mm tactical binoculars is waterproof and fogproof. As an experienced wildlife photographer my top priority was optical quality, and I did alot of research before deciding on this pair. Pre-moistened lens cloths give safe protection to your lens.

The coating reduces glare and protects your eyes from UV rays, and increases the definition and clarity of an object. Apart from magnifying images, binoculars offer other functions also. Another important number describing binoculars is called field-of-view.

When you're trying to spot game that blends in with its surroundings, you need every edge you can get. If you are still in your twenties you can probably use all of that 7mm exit pupil above as your pupils will dilate to about that size in very dark conditions, however as you get older your pupil does not dilate more than about 4 to 5 mm so large exit pupils are wasted. They enable the user to spot far more stars, comets, galaxies, and nebulae far better than with the naked eye.

From little twinkles to bigger twinkles in the sky, the effects of using binoculars makes a big difference. There is no such thing as one-size-fits-all when it comes to sporting optics.
