Looking for the perfect camera lens can be difficult, there are many unique aspects specs and prices you need to consider and weight for the type of project you will be using it for. It can be easy once you learn what you should look for in your camera lenses. Each one executes its functions differently and is something to consider for the resulting image quality verses cost.

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.

Another important thing to consider is the focal length of the lens. It establishes the angle of view as well as how subjects are magnified. If you would like your image to have a stretched or exaggerated perspective you will want a small focal length and would use a wide angled lens. If you would like your image to have a flattened or compressed perspective you would want a larger focal length you would use a telephoto lens. Where the photographer and camera is in relation to the photograph is the perspective.

Focal length can be a very useful tool in photography, so this can be an important feature you may wish to have. Other factors may influence your decision as well, telephoto lenses are more susceptible to camera shake, small hand movements may become magnified in the image. As well they require shorter exposure times in an attempt to minimize the blurring. Wider focal length lenses tend to be more resistant to flare.

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.

You may wish to consider the lens aperture. Aperture is the amount that the lens is able open up or close to let in more or less light. Apertures are listed as f-numbers, to describe their light gathering ability. The larger aperture openings have lower f-numbers, and are considered faster.

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.
