Learn How To Learn How To Be An Intelligent Camera Lenses Shopper.

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.

Most cameras have several lens elements. Each lens element bends the light to try to accurately portray the image on the digital sensor. Optical aberrations occur when the light has not been portrayed correctly on the digital sensor. The result of which could be reduced contrast, image blurring, distortion, vignetting, or colors being misaligned.

Lens focal length plays an important role in the image as well, it determines the angle of view and how an object will be magnified. A wide angle will have a small focal length and stretches or exaggerates the perspective while a telephoto lens will have a larger focal length and compresses or flattens the perspective. Perspective is where the photographer is in relation to the image being captured on film, that being said some 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.

There are many advantages to using the zoom lenses. You can achieve different perspectives and different compositions without replacing the lens. With a zoom lens you can change the composition of the image without any cropping. There are two types of lenses for zoom, optical and digital. If you wish to have the image bent and distorted, also called interpolating, after its been attained you would use the digital zoom lens. If you wish to have the light magnified before it reaches the digital sensor, then you would use the optical zoom lens.

Another lens is the prime lens, they have many advantages as well as disadvantages. You cannot change the composition of an image unless you crop it. They weigh less, and are faster than zoom lenses as well as easier on the wallet. An affordable prime lens is equivalently comparable, if not better than, in terms of image quality as a fair quality zoom lens. A good prime lens provides better light acquiring than a rapid zoom lens, something you have to consider for low light.

The aperture is an extremely important feature for a camera and something you will probably wish to consider as well. Aperture is the measure in which the lens opens up or closes at to allow in more or less light. They are listed as f-numbers to characterize how well they gather light. The lower the f-number the larger the aperture, and the faster they are.

This can be quite confusing, when the f-number is higher the aperture size is smaller, the required shutter speed is slower and the depth of field is wider. Conversely when the f-number is lower the aperture size is larger, the required shutter speed is faster and the depth of field is narrower.
