This is an introduction to various types of Camera Lenses, the most important part of a camera, their characteristics and specific usage.

What is a Lens

In simple words, a lens is the eye of a camera. Technically speaking, a lens is an optical device which transmits and refracts the beam of light. Generally, the lenses are made of high quality glass or plastic. There are two major groups of lenses, Simple and Compound. A simple lens can be described as a single element lens. Compound lenses are collection or group of simple lenses.

There are many types of simple lenses, including Bioconvex, Planoconvex, Positive Meniscus, Negative Meniscus, Planoconcave, Bioconcave. (See the image)

Usages of Lenses
A lens is the most essential and most valuable part of Cameras, Telescopes, Microscopes, Film Projectors, Spectacles, Goggles etc. Besides them, lenses are used on large scale in optical machinery.

Camera Lenses

Camera lens is a very high quality compound lens fixed in a cylindrical body. Camera lenses are coated with a special transparent anti-reflective thin film which does not allow the light to reflect. The anti-reflective increases the quality of the lens. Camera lenses are expensive and many times their prices are equal to or more than the body of a camera.

In Single Lens Reflex cameras, known as SLR Cameras, you can remove the lens from the camera and use another lens.

You can find the specifications of a camera lens on the front side of the lens, which includes Focal Length, Highest Aperture, Diameter, Brand Name etc.

There are many types of Camera Lenses. Different types of camera lenses are made for the specific requirements of the photographer. Please read the table at the last part of this article, describing the angles of views of the lenses of various focal lengths.

Here is an introduction to various types of Camera Lenses:

50mm Normal Lens
50mm Normal Lens

Normal Lens

A normal lens is one which gives natural field of view, i.e. a view which is natural for human eye. So a normal lens gives us a normal angle of view.

24mm Wide Angle Lens

Wide Angle Lens


The field of view depends on the focal length of the lens, and the size of the censor. Lower focal length gives you wider view, longer focal length gives lesser field of view. Wide angle lenses have lower focal length, so they give us a wide view.

Telephoto Lens

Telephoto lens has higher focal length. These lenses are used to take photographs of objects which are far away, like a person on other side of the road, or even the moon.

Zoom Lens

A zoom lens is a lens with variable focal length. So most Zoom lenses can work as a Telephoto lens, Normal lens and wide angle lens. Some zoom lenses have variable higher focal length, so they are used for telephotography. Some Zoom lenses have normal and lower focal length, and they are used for wide to normal view photography.

Zoom lenses is collection of too many lenses, so the sharpness and quality of the image is slightly decreased.

In digital cameras, besides the optical zoom, there is another zooming known as digital zoom.

By using a zoom lens, you can go closer or away from the object without leaving your point.

Macro Lens

Macro lenses are used for extreme close up photography. The special design of macro lens allows you to take images of the object in larger size than the original size. By using macro lenses, you can take high quality photographs of small objects like grains, insects, flowers, coins, stamps etc.

Normal digital cameras have 'macro mode' for taking close up photographs.

Mirror Lens


Mirror lenses are compact telephoto lenses. Normal telephoto lenses with higher focal lengths are bigger in length and are heavy, but a mirror lens of same focal length is shorter and light weight, when compared to the former. A mirror is used in this type of lens which reflects the image. This helps the lens to keep it compact. (See image)

Fish Eye Lens


Fish Eye Lens is an ultra wide angle lens. The focal length of such type of lens is very low, and it captures a view between 180 to 185 Degrees.

    When it comes to choose a camera many people are confused. Choosing a camera lens depends on what kind of photographer you are.

    Thanks for this useful and informative article.

    I've been quite interested in photography but not this interested, I guess. I didn't bother to learn about the different camera lenses. I always only rely on what is in the camera and just use it. I'm guessing that they're just the simple and normal lenses that you've mentioned. Great hub.
