Digital SLR Camera Lenses

The lens you mount on your single lens reflex (SLR) camera can make a dramatic difference in the quality and impact of your photographs. Indeed, one of the main advantages of the SLR over point-and-shoot (PnS) digital cameras is the ability to remove one lens and replace it with another. But newcomers to SLR photography often think in terms of simply exchanging one lens for another one with a wider or narrower field of view. They’re thinking only in terms of zoom positions (wide-angle and telephoto lenses).

Know What Lens To Use

There is so much more that add-on lenses can do for you. Yes, you can mount a wide lens on your camera when your back is against a wall and you need a lens with a wider perspective. Wide lens are great for interior photos, pictures outdoors in crowded surroundings, and for those times when you want to take advantage of the wide-angle lens’s perspective "distortion".

Zoom lenses (telephoto lenses) bring things closer or reduce the range of sharpness, so you can choose which portions of your picture are in focus, and which are not. These long lenses can seemingly compress the relative distances, making objects that seem widely separated appear to be right next to each other.

Digital Camera   Lenses

There are also macro lenses that let you focus as close as an inch or two from the front of the lens, and lenses that are admit much more light to the sensor (faster), so you can take pictures in lower light levels or at shutter speeds that freeze action.

You have to know the importance of the features available with many different categories of lenses.

Some lenses offer extra sharpness for critical applications where images will be examined closely or enlarged. Some have special features, such as vibration reduction (also called image stabilization), which partially counteracts a photographer’s unavoidable shakiness. There are even lenses that provide intentionally distorted fish-eye perspectives that can be used as a special effect.
