A camera lens is one of the important components of a camera. It is also popular under the name of a photographic lens or photographic objective. It is an optical lens or collection of lenses used in combination with a camera body to form images of objects. The images are formed either on photographic film or any other media capable to store images chemically or electronically.
The lenses found in different imaging devices such as a still camera, telescope, video camera or a microscope work on the same principle. The difference arises only in the detailed design and construction.
These devices are of many types. Some of the prominent ones include:
Zoom lens
It is a mechanical set of lens elements for which the focal length variates with the movement of internal elements. The device is used on a large scale in cameras and binoculars these days in order to bring distant objects closer. The devices are also known as para focal lenses because they can uphold the focus of the image even while changing the focal length. These gadgets have made it easy for photographers to capture even the far-away objects clearly and effectively. As a result, their demand and popularity among photographers is increasing day by day. Two popular types of zoom found in cameras these days is optical zoom and digital zoom.
Standard lenses
These are used for street photography and documentary that demand quick movement and action. With the rise in popularity for street photography and documentary, the demand for quality lenses is also increasing. The devices support a focal length range of 35-70mm.
Special-purpose
Some of the major special-purposes lenses are fish-eye, infrared, ultraviolet, swivel, stereoscopic, process, soft focus, etc. All these devices play a significant role in photography enabling one capture better and sharp images even in low lighting conditions.
Macro
This type of lens is used primarily in macro or "close-up" photography. It produces an image on the focal plane, which is of the same size or larger than the subject being imaged. It can support any focal length. The key factors that determine the focal length include its practical use, magnification, access to the subject, required ratio and illumination considerations.
Portrait
These devices are also known as medium telephoto lenses. The devices are mainly used by the portrait photographer who mainly requires a focal range between 80-135mm. This much focal length offers perfect framing for head and shoulder shots. The gadgets are reasonably priced and deliver extraordinary results.
All these devices play a momentous role in photography.
