This telephoto zoom lens is designed with Canon's Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon's 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. This new EF-S telephoto lens with great features delivers excellent performance at an affordable price for all photographers.

Telephoto lenses are an essential tool for digital SLR cameras

E 'useful to think of the camera telephoto lenses, such as telescopes for your digital SLR camera. Like a telescope, a telephoto lens to enlarge the subject, approach and makes it appear larger in the viewfinder and the camera sensor to digital.

Lenses with a focal length longer than a standard 50mm lens can be called telephoto lenses. In practice, however, is considered as the fixed focal length or shorter than 85 mm fixed focal length, while the telephoto zoom,the short side of the telephoto lens starts at 70 mm, as in a 70-200mm telephoto zoom.

Slr

The higher the focal length of a lens, the greater the magnification. So a 100mm telephoto lens is twice the magnification of a standard 50 mm lens. In practice, this means that the problem of height and width in the viewfinder - and the digital sensor or film - is doubled when you connect a 100 mm lens on the camera. Similarly, a 400 mm telephoto lens is eight times (x8) the increase inan objective standard.

If you are on safari and it is a large male lion looking up from 50 feet away, he will appear very small in the viewfinder of a 50mm lens on digital SLR camera. Go to a 500mm telephoto lens, and the lion is 10 times magnification. Now it is almost fills the frame, and you can even see the scars on his face and piercing yellow eyes boring in on you.

The above example should be clear that lenses be valuable if you can not getclose enough to the topic of photographing you. With a telephoto lens you can take, for example, sports shots margin or take pictures of wildlife from the safety of a vehicle or hide.

They are also very useful for snapshots of children, for his report or any other situation where you do not want to be noticed, as you shoot, unnoticed, while there may be a certain distance from the subject.

medium telephoto lens in the range from 85 to 105 mm are also very popular asPortrait lenses, as they tend to flatter the subject and provide a shallow depth of field that raises disturbing background out of focus.

v The first telephoto zoom

telephoto fall divided into two main categories:

1. A fixed focal length, or prime, telephoto lenses
2. Telephoto zoom lenses with variable focal length

1. first telephoto lenses offer the best image quality because they are less transparent and may require less compromise. Their main disadvantage is the fixedThe focal length, limiting the options for the composition of the shot.

When shooting fast-moving subjects like sports or nature, is suddenly the subject is likely larger in the viewfinder. Tele focal length lenses can also be large, heavy and expensive.

However, they are the first choice for professional sports, news and wildlife photographers because the image quality can not be beaten and have wider maximum aperture than zoom lenses with equivalent focal lengthLength.

This enables you to shoot in low light, often a necessity for professional photographers in the following situations:

* Shooting under artificial light at night or riding arenas;
* Pet photographer shooting in the early morning or late afternoon when the animals are most active and the light is soft and less contrast;
* Photography News, when taking photos in a variety of breaking news situations, when they are away fromthe question on the use of flash or you want a more natural look of their images available light.

Within the family of Prime lenses, some of the most important are:

* 600mm f/4.0 - Pets and sports such as surfing and cricket, where these huge lenses can be securely fastened with a heavy tripod, so they are stable.
* 300mm f / 2.8 - a brilliant goal for wildlife and sports for the high luminous intensity with a smaller size and weight that makes it easier to use in combinedthe freedom of a monopod, the photographer more movement. These targets may increase the multiplier of correspondence or extension of the focal length, without a sacrifice in size or weight.
* Target with 85 mm f/1.2 maximum aperture large portrait, which is also good for indoor sports or low-light situations like concerts or theater.

2. Telephoto zoom lenses are very popular because of their versatility and often affordable. lens technology has improved considerablyIn recent years, and now top-of-the-range zoom than the fixed focal length when it comes to image quality.

For all-round performance, coupled with the accessibility and very acceptable image quality telephoto zoom lens is a must-have "lens for most photographers are, the less the purchase of a zoom lens will cost two ( or three) with fixed focal length to cover the same range of focal lengths.

Popular telephoto zoom lenses are:

* Professional quality 70-200mm f/2.8Telephoto zoom
* 80-400 or 100-400 f/4.5-5.6 telephoto zoom
* More affordable 70-300mm f/4.5-5.6 telephoto zoom.

Whatever your situation, also an expert photographer beginner, telephoto lenses are valuable tools that greatly increase the ability to capture great pictures with your digital SLR camera.
