Flexibility in location, a variety of camera is one of the most important functions of a digital SLR camera. The camera is only part of the picture you take. The same goal is very important, as all the pictures you see, that you take. If you are taking a lot of action sports photos, you'll want some kind of lens. If you want a high level of wildlife and nature images, you'd probably have a different type.
If you buy two types of lenses:
- Prime:These lenses have focal lengths are fixed, they are fast and bright, and are of extremely high quality. They are designed for a single focal length.
- Zoom: lets you choose from several focal lengths, this lens is more versatile. However, zoom lenses are not as fast, and there are more aberrations in the photos than with a fixed focal length.
Many SLR cameras are now equipped with a standard zoom lens that ranges from 35-70mm or 28-55mm.
A fixed focal length are the basic ones:
- Standard(50 mm): This is the objective that will come with most cameras. This is a lens to shoot big picture, and gives you a view similar to the human eye. These are compact and lightweight and are beautiful, sharp images.
- Wide-angle (less than 50mm): people, landscapes, wildlife, and to shoot outdoors, in general, choosing a wide angle lens. Are you one of these lenses have a depth of field is very deep, so there is no need to adjust the concentration all the time.
- Medium Telephoto(85-135mm): This is the target of choice for a portrait. This is to isolate the subject from the more image. The greater the focal length also flatten the image a little '.
- Long telephoto (longer than 135 mm): This is what is taken for sport, or other types of shots where you have a framework closely but you can not really use to close physically.
If you want a zoom lens, do one of the following:

And 'cheap, small and very light. He has pretty good image stabilization and has a good zoom range for general purposes. The camera lens works well in an environment of relatively low light, provided that subjects are not moving. This lens is quite slow, which means that the opening is narrow.
The Canon EF-S17-55mm f/2.8 IS USM has a study, the fast opening of f/2.8, image quality and extremely high image stabilization with three stations. This is one of the best lenses on the market generic. This objective has many features, very high image quality and is the first choice of many professional and amateur photographers.
