Looking for a camera lens, but you are not sure whether the more expensive lens is better than the heavier lens? Confused by all the stats? Discover how the perfect lens could be sitting right in front of you. There are many different functions that they perform and knowing what they do will make purchasing camera lenses easier than ever before.

There are several lens elements in many quality cameras. Lens elements bend the light rays in different ways to portray the image as precisely as it can on the sensor. Abnormality may happen when the light has not been captured correctly on the digital sensor. Things such as a blurred image, distortions, reduced contrasting, misaligned colors or a vignette may happen.

To ascertain how an item will be magnified and the angle of view, the focal length will play a key role. When you require a small focal length the image will be stretched or exaggerated in the perspective, you would use a wide angled lens. Projects that require a larger focal length will be flattened or compressed in the perspective, you would use a telephoto lens for these projects. Many people believe that the focal length changes the perspective.

One thing you will wish to consider that may alter your choices is how susceptible and resistant are the features. Telephoto lenses tend to be very sensitive to unsteady hands, the smallest movements can cause cataclysmic results to your photographs as they would be magnified. In order to combat this, they need shorter exposure times to reduce the blurring. A wide focal length lens seem to be more impervious to flares from light sources.

The zoom lenses on a camera has many advantages, you can achieve many different perspectives of the same image without changing the lens. Zoom lenses allow you to change the composition without cropping the image. There are two types of zoom, digital zoom and optical zoom. Optical zoom is where the magnification of light is increased before it reaches the digital sensor. Digital zoom is where the image is interpolated (bent and distorted) after it has been acquired at the digital sensor.

A prime lens is similar to the zoom lens, but has its own advantages and draw backs. They do not allow changes of composition unless you are willing to crop the image. They tend to weigh less than zoom lenses, they are faster and are cheaper. A modestly priced prime lens will perform just as well as a good quality zoom lens, if not better in terms of image quality. They tend to offer better light intake than fast zoom lenses, something you would find important for low light projects.

Aperture is a very important feature, something you will have to keep in mind as well when making your decisions. It is the measurement in which the lens opens and closes to allow light in. It is listed as a f-numbers to define their ability to take in light. The faster is is the lower the f-number will be.

This is probably the most confounding area for most people. The faster the shutter speed, the lower the f-number, the larger the aperture, thus the narrower the depth of the field is. The slower the shutter speed, the higher the f-number, the smaller the aperture, the wider the depth of the field is.
