Photography is all about capturing light on a photographic sensor. The lens and film or sensor, are the most important components affecting the image quality. The lens is also considered the eye of the camera. Lenses give sharpness and clarity to images.

There are various types of camera lenses, which are used, in different conditions. Below are some of the most commonly used camera lenses:

1. Wide-angle lens: this type of lens has shorter focal length. It gives a wide view. A wide-angle lens can focus on the foreground and background simultaneously, another ability that the human eye lacks. Wide-angle camera lenses are best for large, dynamic landscapes where background and foreground both catch the eye’s attention. It is used in landscape photography.
2. Zoom lens: A zoom lens allows the photographer to widen or shorten the lens’ focal length. This feature makes the zoom lens a popular camera accessory in many types of photography, ranging from landscape to portrait photography. A good example of a zoom lens is the popular Canon EF-S 55-250mm 4-5.6 IS. Photographers frequently use this lens.
3. Telephoto lens: a telephoto lens brings the subject “closer” to the photographer, reducing the distance between objects in the photograph and the camera’s lens. This allows a telephoto lens to show greater detail than the human eye could see at the same distance.

There are many other lenses such as fish eye lens (used in underwater photography), close up lens, fixed focal length, and etc but above written are most frequently used camera lenses.
