What’s an slr zoom lens and why should you use one? Zoom lenses were designed to enable you to change the magnification of the lens by using straightforward controls on the lens itself.

A telephoto ( or long ) zoom would sometimes magnify the subject, as you saw it, from normal to larger in order to have your photo appear nearer to the action. A wide angle ( or short ) zoom would move you back from your subject, therefore appearing more distant from your subject and seeing a wider view.

With both kinds of lenses, you might select all of the steps of magnification between. Different lenses will suit differing types of photography, therefore it’s vital to get the proper tool for the right task! Zoom lenses are getting common and well loved by professional photographers, as well as amateur hobbyists.

If you are familiar with DSLR, then you already know the benefits and how important it is to have a zoom lens for your DSLR. Because of its narrow angle of view, a telephoto lens is definitely not going to be like a zoom lens.

However, zoom lenses offer both a wide-angle or telephoto – giving you a wide angle or narrow view, respectively. Your personal collection of lenses should always include a SLR zoom lens, as it can zoom in on your subject as it’s name suggests.

These lenses are available to you in focal lengths that go from of 16mm up to 400mm. These versatile lens can change the background of a particular subject, as well as have the ability to bring the your subject even closer to you. Because of this longer focal length, you can use your camera to separate the subject by blurring the background and have a resulting smooth bokeh surrounding your subject. The result, the subject stands out better.
