Canon Binoculars Figure - The Best Of Canon 18x50 Image Stabilization Binocular

Sphere: Related Content


The 18x50 Image Stabilized binoculars feature a shock-resistant, water resistant rubber coating for a nonslip grip, better durability, good handling, and for protection against rain & splashing water. You don't have to worry about the optics misting up if you get caught in the rain and still need to view. These binoculars render high-magnification and wide-field viewing. Controls for focusing and image stabilization are centrally placed and accessible by both hands. These binoculars provide long eye relief for added comfort and allows the use of eyeglasses without vignetting of the image.

What is an Image Stabilizer?

The more powerful the binoculars, the more shakings are magnified. As a result, even a little sway of your hands will shake the image in the binoculars a great deal. Usually, we can bear this image shake with binoculars up to 7x magnification. The image shake would quickly get unbearable With higher-magnification binoculars.

However, with Canon's Image Stabilizer turned on, the image shake becomes tolerable even at magnifications of 15x and 18x. Such high magnifications were previously unthinkable in a pair of binoculars without the use of a tripod. TheImage Stabilizer steadies the image instantly and brings out the top-notch optical performance of the lenses.

Image Stabilization and More

Canon's IS technology is outstandingly good at eliminating the sway problem and is widely applied by the television industry with Canon's professional broadcast quality video recording equipment. An exceptional VAP (Vari-Angle Prism) corrective IS system sits within the objective lens group and the porro prism on each side of the binoculars. Within one-thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. The VAP shape modifies to refract or 'bend' the light path by exactly the right amount, thus fully compensating for the vibration.

Super Spectra Coating

A number of optical elements affect the brightness of an image, including the total of incidental light that is reflected by the lens. An uncoated lens will reflect away as much as 8% of the incidental light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection.

What do the numbers mean?

8x25? 15x50? The two numbers used to describe any pair of binoculars are their magnification — 8x, 12x, 15x and so on — and the diameter of their objective lenses — 25mm, 36mm, 50mm, and so on. The larger the first number is, the larger the object will appear in the objective lens. To illustrate, if you use a 10x lens and view at an object that is 200 yards away, it looks to be the same size as an object placed just 20 yards away. The second number, the size of the objective lens, is crucial because the larger the objective lens, the more light it can accept for brighter, more detailed images, and the better suited they will be for low light situations.

What Are Big Binoculars And How Can They Be Made Easier To Use?

Sphere: Related Content
The intended use of binoculars may vary. Capabilities depend on the size of the binoculars and the power they have. Specifications and strength of binoculars define its power and its use. The power of binoculars is determined by two parameters: magnification and the width of the aperture lenses or the effect of light. If binoculars are described as [7 x 50], the first letter represents magnification, while the second letter represents the diameter of the objective lenses. In this case the object viewed will appear 7 times closer than if it was viewed without binoculars. The second number 50 represents the propensity of the binoculars to gather light. The higher the second number, the brighter the viewed object will be. One of the uses of binoculars with high second numbers is stargazing, but there is a problem that must be resolved with initial use of these binoculars. The weight of binoculars of size [7 x 50] and above makes it impossible to use by simply holding it up to your eyes and freely viewing objects. Installation of a binocular mount will hold these binoculars in place, providing support.

Binoculars are defined as big binoculars when their specification indicates the second number is 50 or more. Binoculars [7 x 50] are considered big binoculars. These binoculars are physically heavy and their use can be affected because they are cumbersome. Some uses of big binoculars include surveillance, bird watching, hunting, and star gazing. Binocular mounts are used to change the way big binoculars are placed for use. With this renewed change, big binoculars assume their purpose and they are available for use.

A binocular mount is designed to provide support appropriate for large binoculars and small telescopes. The mount requires modification as it is being installed. The mount must be shaped to provide singular support to hold the equipment. It is imperative to find a suitable location for mounting the binoculars. After completing all the necessary preparations, assembly of the mount is completed. This support facilitates big binoculars, so they can function with ease.

Binoculars that are very large may not have outstanding features. Maybe they are just big and bulky without much purpose. When purchasing binoculars, it is important to investigate the product so you will know what you are getting.

New optical technology has been introduced bringing everything 80x closer. These zoom compact binoculars are the smallest on the market and they include all the necessary features with high performance magnification and clarity. They produce sharp, high-contrast images. These binoculars allow you to view objects at 20x magnification and then to zoom to 80x with maximum focusing capability, while retaining sight of the object you are viewing.

New ideas on selecting binoculars caution that power ought not to be the chief goal when choosing binoculars. Consideration of light gathering, field of view, and ease of use are also important. Binoculars with too much magnification can weigh too much, and this equipment may be too uncomfortable to use for very long at a time. These binoculars require a mount and use will have some limitation. Bigger is not always better. Consideration of the intended use of binoculars will be helpful when ordering equipment.

World Of Binocular

A bird watcher needs to be able to see feathers in dim light, and have strong magnification. They should also be able to focus on close objects, have color viewing, and a large field of view in order to see the bird well. They should also be light and have a strap to carry them on, and be comfortable for the user. It's a great idea to get birding binoculars that are waterproof and can also stand on a tripod, since you never know where the birds will go. Binoculars for bird watching are classified by two numbers: the first giving us the magnification and the second, the diameter of the lens. It is a good idea to keep the magnification of bird binoculars fairly low, usually around 8 times, in order to lessen the impact of natural hand shake, and to keep the field of vision sizable. A larger diameter gives a clearer image because it traps more light, and it also widens your field of view. The most popular are 40mm and 42mm, because any larger can make bird binoculars heavy and hard to use. To fully enjoy bird watching and to sharpen your bird identification skills a good pair of binoculars is a must especially if you want to take your hobby further. Price You should buy the best binoculars you can afford. A pair of quality binoculars is essential, especially for pro bird watchers. Binoculars can range in price from under 25.00 to well over 1000.00. When you are starting out it may be tempting to buy a very cheap pair of binoculars. However, this is false economy as they will probably lack features which are needed for bird watching and you will not enjoy your hobby so much. An upfront investment will set you on the road to many years of bird watching enjoyment and your binoculars should last just as long. Many novice bird watchers make the mistake of buying binoculars with a high magnification thinking that the greater power will enable them to see birds more clearly. However, although the birds will appear closer and larger, as magnification increases your field of view decreases and slight movements made by an unsteady hand or a gust of wind are greatly exaggerated. High powered binoculars can also make the eyes tire easily so for general bird watching choose a magnification of 7x or 8x. If you are using a hide or viewing hawks and waterbirds over large expanses then choose a magnification of 10x. Do not choose zoom binoculars for bird watching - they do not give as good an image and are more likely to develop faults.

Marine Binoculars

Sphere: Related Content
If you like fishing or any other marine activities that might include using a boat then you should get yourself a pair of marine binoculars. These are extremely useful for spotting things that might be in your path, or which are there as a safety reminder e.g. buoys and markers. These binoculars are a terrific aid to your night time vision and to the distance that you can see, marine binoculars are waterproof and an indispensable aid to water activities.

For those who are new to marine binoculars the 7x found in the binoculars reviewed below for example, refers to magnification, thus things are magnified seven times and this is felt to be the maximum amount of magnification that can be properly handled when out at sea. So 7x50 referred to below is the magnifying factor times the size of the lens, which is generally 50mm. So 7x50 is the most generally accepted size of binoculars designed for marine use – this is because that particular combination gives a steady image along with the maximum of transmitted light that can be accepted by the human eye.

Nikon have a number of different models of marine binoculars, one of the more popular sets seems to be the 7x50 CF Waterproof Ocean Pro Binoculars which come complete with their own case. The Nikon 7x50 is constructed from durable lightweight polycarbonate and has a number of useful features, its 50mm objective lens allows for maximum light gathering and the large central focus knob makes it easy keep your focus. The field view is thirty eight feet at a hundred yards and the fold down rubber eye caps are designed to protect the eyes from bumps in rough waters - these binoculars are both waterproof and fog proof.

The Steiner 7x50 skipper marine binoculars with compass is more expensive than the Nikon 7x50 but has a number of extra features. These binoculars come with highly crafted optics for greater brightness and enhanced contrast; cat optics provide the brightest possible images when light is low and enhanced contrast in rough weather and bright sunlight. The high quality optics are designed to protect the eyes from harmful UV radiation and the Steiner Sports-Auto-Focus is designed to give the wearer maximum comfort. Steiner 7x50 skipper marine binoculars body is made from shock absorbent makralon fiber reinforced polycarbonate with slip-proof rubber armor. These binoculars come complete with carry case and lens straps and are ideal for boating activities.

When you buy marine binoculars there is often a choice between waterproof and those that are non-waterproofed; waterproof binoculars are more expensive but are specially designed for wet conditions. Some binoculars will have waterproof written on them while others may say nitrogen filled, which means the same thing.

InfraRed Binoculars - What Are They And How To Buy Them?

Sphere: Related Content

InfraRed binoculars (also called IR binoculars and night vision binoculars) are binoculars that provide you to see in the dark and trough the fog. Normal binoculars can't do that, but thanks to modern technology, InfraRed devices are already built in binoculars. Many people nowadays need infrared binoculars - birdwatchers, cave explorers, security and military personnel.

InfraRed binoculars give a wonderful chance for birdwatchers to discover the nature at night. For example night birds or animals like owls, how will you be able to see them, without special night vision equipment? InfraRed binoculars are more expensive than regular ones. InfraRed (which means under red) means that any device with an infrared "detector" can "detect" "invisible warming", which means almost every object that we can find in nature is relatively warm, but we can't see that, thanks to infrared binoculars this is now possible. Almost every object makes an infrared radiation, and thanks to these "detectors" we can see these so called "hot spots" so "detectors" can find them, and make an image which is possible for a human eye to see. And thanks to infrared devices, doctors can find hidden tumors in the body, biologists can even find diseased vegetation in a forest and engineers can find leaks in mainstream heating systems.

When buying InfraRed binoculars, please, read all the features that specific binoculars provide. Maybe you are overpaying, by paying for the features which you don't need or you will not use. But then again, don't try to cut the price off too much, almost every time price reduction means - reduction in quality. Another thing to keep in mind before buying, is to make sure, that it will have all the additional features which you need, for example waterproof if you will use them near water, sealed if you will use them in caves or in dusty terrain and so on. InfraRed binoculars are also great, that human eyes don't need to adjust the dark, the special lens which is in the binoculars does that. If you will try to adjust your eyes to see in dark for a longer period, it could damage your eyesight, so by using InfraRed binoculars your eyes will not have any pressure at all. The beam that is generated by InfraRed will cause reflection of all near objects and then come back to the lenses of the binoculars. The lens will make an light beam, so our eyes can see, and this way there is no pressure to be made by our eyes.

Infrared binoculars are truly worth it's price, even if they are more expensive than "regular" binoculars. If you need night vision binoculars, then InfraRed binoculars are probably one of the best options. They also have their minuses, the range and field of view will be reduced, the range will be that far, how far are the "hot spots", if there will be no warm objects, then the vision of infrared ends there.

How to Buy The Right Binoculars For You

Sphere: Related Content

Binoculars are wonderful pieces of equipment that can enhance many of our daily activities including, birding, action sports, hunting, and even astronomy. Essentially binoculars take a distant image, enlarge it through the use of lenses for viewing, all while remaining small and light enough to be mobile.

The actual makeup of most binoculars is fairly straightforward and simple. You have the lenses at the end of the barrel called the objective lens that gathers the light from the distant image and focuses it on the lens closest to your eyes for viewing. Binoculars are really two small telescopes put side by side so that you can view the desired image with both eyes instead of just one. This imparts some measure of depth of field, much more so than with a single scope.

When selecting a pair of binoculars you will immediately find that two numbers are used to describe their capability. These numbers are often expressed as "6 X 30" or something similar. Let's break the code so you will know what these numbers mean.

The first number refers to the magnification power of the binoculars, or in other words how many times the image is magnified. So if the number is 6, that means that the image that you view through the lens is magnified 6 times it's normal siZe.

The second number has to do with the size of the objective lens at the end of the binoculars.It's good to know this number because the larger the diameter of the objective lens, usually the more light will be let in for viewing the distant image.

Now, let's put this information in use in the real world. You may think that it's best to just get the highest magnification that you can get for binoculars, but this is not true. At some point, hand holding the binoculars will affect the clarity of a highly magnified image and the resulting shake will render the magnification benefits useless. Generally speaking, anything above ten times magnification should be mounted on a tripod instead of handheld. So if you are planning to use binoculars for activities that do not allow you to be able to bring along a sturdy tripod, you probably want to stay with a pair of binoculars with 4 -7 times magnification.

As far as light gathering properties are concerned, if you plan on using your binoculars in any kind of low light situation whether indoors, or at times of day when there is low available light outdoors, then you need to have a large objective lens, usually 30 or above, to make as much use of available light as possible.

Finally, consider the weight of the binoculars before buying them. If weight will be a consideration for activities such as hiking, then perhaps plastic lenses will be best that are specially coated to produce a high quality, sharp image. These can be more costly than glass lenses, but they are considerably lighter. Glass lenses usually make for much better optics and clearer images at a lower overall cost, but they can also be more fragile.

Generally speaking, more expensive pairs of binoculars have more atention paid to fit and finish and will stand up to more vigorous use, but if you only plan to occasionally use your binoculars, then a less expensive pair will no doubt work fine. Also, remember that after the purchase you should be sure to protect your investment with a suitable binoculars case.

Nightvision Binoculars Can Come In Handy In Many Situations

Sphere: Related Content


You never know when you may need to see at nighttime. You may find yourself hunting at night, you may be playing paintball with your friends in the dark woods, you may be looking for intruders on your property that have alerted your dogs, or you may just be bird watching at night. Whatever your reasons, you'll love a pair of nightvision binoculars. You'll be amazed at how they magnify the light even when it seems there isn't any to be magnified. The military used to be the only ones with their hands on this sort of technology. They still use them to this day for nighttime military operations, even going so far as to put nightvision binocular scopes on their rifles for night sniping missions. However, just like compact binoculars moved from only spies using them to the general public, nightvision binoculars are also now available for anyone who wants to buy them.

Magazines And Army Surplus Stores

There are many magazines that highlight the newest technology to move from military issue to the general public. You can often order items such as nightvision binoculars from these magazines. Army surplus stores are also great ways to get military issue gear that has moved to the civilian population. You should check both of these avenues to see if they have the nightvision binoculars you're looking for. These are the perfect way to get your hands on the perfect pair of binoculars for whatever you may be using them for.

The Internet

Nowadays, there's not much you can't find on the internet. You can definitely find nightvision binoculars online and you can probably find them at a price you can afford. The great thing about buying online is that you can often look at consumer reviews to see how people may have liked the product or may have found it less than satisfactory. However, make sure you take any reviews with a grain of salt. Anyone can have a bad experience but if you find many bad reviews for one product, you can be sure that those nightvision binoculars aren't worth your time or money.

There are various types of nightvision binoculars. There are cheap ones that can be used for any situation and then there are the more high powered versions that are more in tune with what the military uses. Depending on what you need them for and how much you have to spend, there is likely to be a pair of binoculars to suit you and your needs.

Everything You Need To Know About Binoculars

Sphere: Related Content
Binoculars are the world’s most used type of optical instrument. They have many different uses, and choosing the right pair for a particular application is crucial. There are binoculars for astronomy, bird watching, marine, military, hunting, opera, compact, digital, and more. As you can see there are quite a few different types of binoculars that you can choose, from but one of the most popular are the digital binoculars.

Terminology

There is some binoculars terminology that you are going to need to be aware of if you want to make sure that you choose the right pair for you and your needs. The field of view is very important, and this is the amount of territory that you see when you are look through the binocular.

Two things determine field of view and these are magnification and eyepiece design. The exit pupil in a binocular is the actual width of the beam of light that leaves the eyepieces and is measured in millimeters. To see an exit pupil all you need to do is hold the binocular at arms length and you will see a circle of light in each eyepiece. This circle is the exit pupil, and to calculate the exact size of the exit pupil, you simply divide the first binocular number into the second binocular number.

It is important to check out the exit pupil when you are trying to decide which pair to buy because a large exit pupil is easier to keep centered on the eye and this is a major advantage. For instance when it is difficult to hold the binocular steady such as on the deck of a moving boat.

The twilight factor will also play a major role in deciding which pair is going to be right for you. This is a mathematical formula that predicts the amount of detail that can be seen in low light. Twilight factor is the square root of magnification multiplied by the objective.

How To Choose

It can definitely be tricky to decide on a pair of binoculars for yourself, especially if you have never done it before. There are so many different options staring back at you from the shelves, but as long as you keep these helpful tips in mind and remember to choose the right pair, depending on the specific application you are going to be using them for, you will be alright.

This information will help get you well on your way to finding a pair of binoculars that will be perfect and last you a lifetime.

Learning About Camera Binoculars

Sphere: Related Content
There is actually quite a bit of information that you are going to want to know about camera binoculars. These are a very popular purchase, probably because they have so many different uses. Camera binoculars are used for everything from watching the opera and sports to bird watching, and everything in between. If you want to learn more about camera binoculars, here is some important information that you are going to find very helpful.

What They Are

Binoculars are two identical or mirror-symmetrical telescopes mounted side by side and which are aligned to point accurately in the same direction, allowing the person looking through them to use both eyes when viewing distant options.

Types Of Binoculars

Most likely you have already heard of digital camera binoculars, but there are various other types that you can choose from as well. There are zoom binoculars for one, which are one of the most common type of camera binoculars. They have part of the ocular lens arrangement moveable so as to adjust the magnification, typically from about 7x to 20x zoom. In order to keep the images clear and in collimation, the quality of engineering needs to be very high. For this reason, most zoom binoculars will tend to go out of collimation and have a blurred or double image at the higher magnifications.

There are also specialist binoculars that are quite popular, and although the general design remains the same, binoculars are available for all specialist purposes. Waterproof binoculars for instance are available, and sometimes incorporate a compass and are used for marine use.

Another of the most popular types of camera binoculars are marine binoculars. These binoculars are most commonly found in a 7x50 rubber-armored design, and the reasons make sense, as low power is easiest to deal with when you are on a moving boat and because they are easy to hold in your hands while also making you feel the least queasy.

Keep in mind that these are just a few examples of the various different types of camera binoculars that are out there for you to choose from. You can really only determine which are going to be the best for you after you have decided what purpose you need them for.

Also remember that there are some knowledgeable and professional experts out there who know everything there is to know about binoculars and who are definitely going to be able to help you out here and ensure that you choose just the right binoculars for you and your needs.
