A Short Review of the Canon 10x30 IS Binoculars

!9#: A Short Review of the Canon 10x30 IS Binoculars

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.

Canon IS Binoculars - No More Shake

!9# Canon IS Binoculars - No More Shake

[if ]
[endif]

There has been huge interest in Image Stabilized binoculars in recent times. The technology has become more affordable in recent years so it look set to continue growing its share of the binocular market.

Why the interest? It's all down to resolution. IS technology allows you to see more detail in the image because it greatly reduces the natural image shake caused by unsteady hands and yes we all have the shakes, its just a matter of how much! Try focusing normal binoculars on some text, perhaps on a street sign some distance away, while holding them then try again with the binoculars on a tripod. Notice the difference? You can see much more detail in the steadier tripod mounted binocular. Reducing or eliminating the shake gives us much better detail.

Canon IS binoculars are probably the best known of the bunch while brands like Fujinon are fast gaining a following. IS binoculars are used by nature observers such as birders and sailors amongst others. Whether you're viewing wildlife from the back of a moving jeep or you've had too much coffee, the stabilization is very effective. Sailors like their ease of use and water resistance while astronomers appreciate the power and clarity of the optics. With a steadier image we can achieve greater magnification more comfortably. Sailors used to be pretty much limited to 7x magnification but IS technology now allows up to 18x with the same aperture.

Their inbuilt computers and gyros are very effective at reducing image shake. The gyros measure both horizontal and vertical movement which the processor instantly compensates for by moving either variable prisms or a tilt mechanism depending on which particular model you have.

Fitting the electronics and batteries into the body adds weight so these do not feel like a normal binocular. Having said that, one soon gets accustomed to holding the weight at least for short durations.

The Canon 10x 30 is lightweight as IS binoculars go at a shade under 1.5lbs and is water resistant, think showerproof not waterproof and the rubber coating makes them comfortable to hold. The combination of weight, quality optics and price seems to have hit the mark with IS fans. The 14.5mm eye relief also allows most folk to use them while wearing glasses.

Canon make IS binoculars in several sizes: 8x 25, 12x 36, 10x 42, 10x 50, 15x 50 and 18x 50 but the 10x 30 seems to be the most popular.

What is Canon Image Stabilization?

What is Canon Image Stabilization?

Canon image stabilization technology, many times referred to as "IS," is a feature found on many of the lenses in Canon's lineup. Many photography novices or recent film to digital converts wonder if IS actually provides better results. This is a good question as Canon IS technology adds weight, size, and increases the price of almost every lens it is included as a feature on. This article is going to look at the advantages of Canon image stabilization in light of these downsides.

How does Canon IS work?

Canon's IS system works with an optical image stabilizer. The stabilizer is an extra floating optical element that is added to existing lens optics. It is designed to detect lens movement and correct for it by altering the path light takes through the optical elements of the lens on its way to the digital image sensor. A series of electromagnets help perform this task. As the movement sensor only detects when the lens moves, and the floating element can only correct for lens motion, IS only works to reduce blur in image subjects that are not in motion. In other words, Canon image stabilization cannot freeze the motion of a moving object in low light conditions, it can only reduce (or eliminate) the effects of camera shake when hand holding at low shutter speeds.

Is Canon IS really it?

Many photographers find Canon IS to be an invaluable tool in many different lighting conditions. Most Canon lenses equipped with IS allow for excellent results in hand held (non-tripod) photography while shooting 2-3 stops lower than lenses without IS. Some Canon lenses with IS will work 4 stops lower than normal. Furthermore, under the lowest of light conditions and while hand holding, some users have noticed that consumer grade Canon IS lenses outperform some of the much more expensive (and sought after) "L Series" lenses that do not have image stabilization. Canon image stabilization definitely improves results while hand holding.

Canon does offer a few recommendations for use of IS. First, you do not need to use it when your lens is mounted on a tripod. Canon actually recommends that you disable IS when tripod shooting to avoid image distorting effects.

Second, the IS feature requires extra power and can drain your camera battery quickly. Therefore, it is best to turn it off when not shooting in low light conditions.

Binocular lens coatings

Introduction.

Binocular lens anti-reflective coatings are often less understood, but one of the most important in relation to the quality of the binoculars. Lens coating to determine how well you're going to see your photos, the clarity of colors, resolution and contrast.

Background.

Recognize that there are a number of internal glass surfaces binoculars. As the light passes through the front of the lens, it travels through the binoculars. Howaffects each set of coated glass surfaces around 5 percent is reflected (lost). Assuming groups of ten internal glass surfaces, the same time reflecting the loss of 5 percent each for a total of 50 percent of the loss of light as the image reaches the lens back. The result is a cloudy, hazy, blurred image.

Anti-reflective lens coatings allow a higher percentage of light passing through each row of glass surfaces. Instead of the loss of 5 percent, can be coated lens to reduce imageless than 1 percent. A smaller percentage of the light is reflected to the eye and a larger amount later. At best, high quality binoculars for over 95 percent of light reaches the lens of the eyes and the eyes. The result is a crisp, clear images and bright.

Types of lens coating.

Binocular lens anti-reflective coatings are classified into one of four categories.

Objective 1 covered. (C) a single coating contains at least one group of extensionsA series of glass surfaces. The first set of lenses and the last are well covered, but the rest of the sentence is not likely to:

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

Note: In general, coated lenses covered only the first and last goal of the binoculars. The slow first and last are the ones who can (the lens front and the back of the lens of the eye).

2 Fully coated lens. (MC) contains a single layer on all series of the inner row of glass surfaces. Each setreceive a unique coating of the lens:

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

3 Multi-Coated Lens. (FC) contains more coatings on at least one set of the series of interior glass surfaces. Often the first and last lenses are multi-layer, while the remaining lenses can be coated individually:

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

4 Fully Multi-Coated Lens. (FMC) Provides multiple coatings on all glass inner row setSurfaces. Each set of lenses are fully multi-coated:

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

As we demonstrated with our four categories, which are higher-level models Fully Multi-Coated, compared to the other three categories.

The coating process.

Lens coating is a process in which certain chemicals (such as metallic, silver or aluminum) are physically applied to the glass lenses of the binoculars to allow light to pass through, and notresist. Generally, the coating can reduce reflection of light from 5 percent for the untreated glass of 1 percent for a lens coated. Commonly used multi-layered magnesium fluoride or calcium fluoride to further reduce reflection. Each glass is usually 3 to 5 times removed (and sometimes upwards of 10 times), a situation that has reached almost 100 percent of light to create the eyes.

Closing a summary.

Listen carefully to the seller, or understand what you read, if youIt is located on the lens coating. The type of lens coatings go a long way toward determining the quality of the image we see.

or Fully multi-coated lens provides the best image quality.
or Multi-Coated Lens is one step below the best, but they continue to produce high quality images.
Fully coated lenses for good or images that are acceptable for most users.
or coated lens is usually found in most cheap binoculars.
