The Purposes Of Camera Lenses

By Grant Funshallen


Most of us spend some time looking at photographs taken long ago. Those pictures bring back sweet memories and make us feel lighter and happier. With camera mobiles in hand, it is common to makes use of every opportunities and take a picture to have as a memory.

But haven't you felt that certain pictures are clearer and bring out the content more beautifully. The quality of the image depends on the lens in the camera. The quality of the camera lens is very important. And even a basic camera can take a good picture if it has a good lens.

A lens is nothing but a piece of curved glass. Light can travel in any direction when it enters a glass. Therefore, the lens receives the light rays through the aperture and channels it to the focal point to form an image. The aperture size determines the quantity of light entering inside.

Using the right lens for the right image becomes important as the lighting and environment affects the quality of the picture. Knowledge of this becomes vital especially to people who use a camera in their profession. The distance between the lens and the film is referred to as the focal length. It represented in millimeters.

The type of the lens depends of the focal length. The lenses with a standard focal length are the prime lenses and the lenses that allow the adjustment of focal lengths are zoom lenses. The ultimate picture is largely dependent on the intensity of light gathered and focused by the lens. The lens is moved far from the film to focus on a closer image.

An object far off can be captured to look closer with proper use of the lens. The entire picture can look different, clear and better if the lens is used properly.

With the advancement in science, all the lenses available today are of good quality. However, there are various types meant for various uses. The lens with a wide aperture would generally cost more as it allows shooting even in dim light and is fast. By using the right lens, you will be able to capture images to your utmost satisfaction.
