One of the best things about observing wildlife from a distance is that you get to see everything the animal does without it even being aware of your presents. You can learn a lot about the animal you are observing by doing this, but there is usually one small problem.

If you are using regular binoculars to view wildlife through, and you don't have a tripod setup, then the image tends to be a bit shaky and this can be very annoying and you may not be able to observe very well. This is where the Canon 10x30 IS binoculars can be a big help.

The Canon IS binoculars, or Image Stabilized binoculars, use a new technology to basically eliminate shaking that is caused by natural movement in your hands. I won't get into how it works in this article, but if you do any activates like bird watching or stargazing, these binoculars will help eliminate almost all the shaking that is caused by your hands leaving you with a crystal clear image.

Now in case you are wondering, the 10x30 means you get a 10 times magnification so anything you are looking at is going to be 10 times closer than if you where looking at it with your naked eye, and the 30 means that there is a 30 millimeter diameter across each lens which means you have a wider view compared to say a 25 millimeter lens.

To activate the image stabilization on the Canon 10x30 IS binoculars all you have to do is push and hold down the button on top of the binoculars. Letting go of the button turns the stabilization off and still allows you to view through the binoculars just like any regular binoculars. This pair of IS binoculars uses 2 AA batteries that usually last about 20 hours with the image stability on.

The Canon 10x30 image stabilized binoculars are a really good choice if you are an avid bird watcher, stargazer, hunter, or just want to use them to view something far away without any shaking.

Binoculars Lens Coatings

!±8± Binoculars Lens Coatings

Introduction.

Binocular anti-reflective lens coatings are often the least understood, yet are one of the most important features relative to the quality of the binoculars. Lens coatings determine how well you are going to see your image, the clarity of color, the resolution, and the contrast.

Background.

Realize that there are a series of internal glass surfaces within binoculars. As light enters through the front objective lens it travels through the binoculars. As it hits each series of uncoated glass surfaces approximately 5 percent is reflected (lost). Assuming ten internal sets of glass surfaces, times 5 percent reflective loss at each, equals a total of a 50 percent light loss as the image reaches the rear ocular lens. The result will be a dim, hazy, unclear image.

Anti-reflective lens coatings allow a greater percent of the light to pass through each series of glass surfaces. Instead of the 5 percent loss, coated lens may reduce that figure to less than 1 percent. A smaller percentage of the light is reflected and a greater amount continues on to the ocular lens. In better, high quality binoculars in excess of 95 percent of the light reaches the ocular lens and your eyes. This results in a sharp, clearly defined, and bright image.

Types of Lens Coatings.

Binocular anti-reflective lens coatings are rated in one of four categories.

1. Coated Lens. (C) Contains a single coating on at least one set of the internal series of glass surfaces. The first and last set of lens are probably coated, but the remaining sets probably are not:

Example: ____ || ____ | ____ | ____ | ____ | ____ ||

Note: Typically, coated lens have only the first and last lens of the binoculars coated. The first and last lens are the ones you can see (the front objective lens and the rear ocular lens).

2. Fully-Coated Lens. (MC) Contains a single coating on all sets of the internal series of glass surfaces. Each set of lens receive a single coating:

Example: ____ || ____ || ____ || ____ || ____ || ____ ||

3. Multi-Coated Lens. (FC) Contains multiple coatings on at least one set of the internal series of glass surfaces. Often the first and last lens are multi-coated, while the remaining lens may be single coated:

Example: ____ |||| ____ || ____ || ____ || ____ || ____ ||||

4. Fully Multi-Coated Lens. (FMC) Contains multiple coatings on all sets of the internal series of glass surfaces. Each series of lens are fully multi-coated:

Example: ____ |||| ____ |||| ____ |||| ____ |||| ____ |||| ____ ||||

As we have shown with our four categories, the Fully Multi-Coated models are vastly superior when compared to the other three categories.

The Coating Process.

Lens coating is a process where certain chemicals (such as metallic, silver, or aluminum) are physically applied to the glass lens of the binoculars to allow light to pass through and not be reflected. Generally, one coating may reduce light reflection from the 5 percent for untreated glass to 1 percent for a coated lens. Multi-coating commonly uses magnesium fluoride or calcium fluoride to further reduce reflection. Each glass is typically coated 3 to 5 times (and at times upwards of 10 times) to create a situation where near 100 percent of the light reaches your eyes.

A Closing Recap.

Listen closely to the salesperson, or understand what you are reading, when a reference is made to lens coatings. The type of lens coatings go a long way to determining the quality of the image you will be seeing.

o Fully Multi-Coated Lens produces the very best quality images.
o Multi-Coated Lens is a step below the best, but still produce quality images.
o Fully Coated Lens produce good images that are acceptable to most users.
o Coated Lens is usually found in the most inexpensive binoculars.

Birding Binoculars

!±8± Birding Binoculars

Birding binoculars describes optics desired by those who enjoy the adventure of birding and the joy of observing nature. Those of us who yearn to get out into nature regardless of the season for the chance of seeing new arrivals into the area or resident but colorful, intriguing species would be ill prepared were it not for the equipment we carry.

Birding is an activity that requires very little in equipment. Fundamentals include a field guide and a binocular. That's it. However, do not think cheaply when it comes to binoculars. It is the opinion of this author that one should consider investing in a very good pair of binoculars in order to ensure years of enjoyment and facilitate identification of the bird in question.

Let's face it, the difference between a Northern Oriole and an Orchard Oriole is substantial. However, the difference between a Spotted Sandpiper and a Solitary Sandpiper are less obvious. The difference between a Rose Breasted Grosbeak and a Blue Grosbeak is also substantial. Yet, the difference between a Summer Tanager and a Hepatic Tanager is not so easily determined. It is those situations where very similarly looking species overlap in territory that one really appreciates the better optics associated with a very good pair of binoculars.

The Vortex Viper is an exemplary representative of the modern trend in binoculars. It is of the roof prism design, making it more ergonomic-more easily held for longer views of the bird you are trying to identify. The roof prism design allows for internal focusing which facilitates water and fog proofing. These are nitrogen purged. Another outstanding feature is good eye relief-a must consideration for those who wear eyeglasses. Phase corrected, fully multicoated lenses provide for true colors and freedom from ghost images. The Viper is well crafted, rubber armored, solid, and well suited for rugged outdoor use. They provide a bright, well formed, distinctive image-exactly what is required when subtle field marks must be noticed. This binocular is mid-priced. The Vortex Viper has been awarded "Best of the Best" by Field & Stream.
