In professional photography, camera lenses are the second most important part. Your camera body is practically useless without any sort of camera lens. Similarly, your photography will be useless without the right set of lens.

For those who have been a photographer for long might be aware of the many lens types, however, those starting to make their up as a photographer are often confused by what sort of lens should they choose. It is a question that bombards lots of newbies and they end up messing their end results.

For the sake of the profession and to answer the queries, Mohit Bansal Chandigarh explains all major camera lenses used big time in the photography profession. But before that, let’s dive into something more important.

Focal Length of Lens

Focal Length of Lens

When you read a lens it usually says 18mm-55mm or 70mm-135mm, this is the focal length of a lens but its not the actual measurement. Here, “Focal length is a calculation of the optical distance from the point where light rays converge to form an in-focus image of the subject to the digital sensor in the camera.”

It tells the angle of view and how much surrounding you can capture through the frame or the magnification of the subjects and objects. For higher magnification, the longer focal length is required while for wider angle view, shorter focal length.

Types of Camera Lens

Prime Lens

Prime Lens

The single focal length lens is lighter in weight and smaller in form factor. The most widely used prime lens with focal length is 50mm. It is expected to be the closest match to human eye magnification. As these lens types are of fixed focal length, they cannot zoom in or out of the subject and yet they produce images with more details compared to their zooming lens counterpart.

Zoom Lens

Zoom Lens

A zoom lens has a variable focal length that can be tweaked with as it has to serve a purpose of closing in on a far away object to capture. Photographers generally use 24-70mm or 24-85mm lens generally. There is also wide-angle zoom lens available like 14-24mm and 16-35mm that are used to capture distant scenes with a wider field of view. The other commonly used lens in this segment are telephoto zoom having a focal length of 70-200mm.

Telephoto Lens

Telephoto Lens

A telephoto lens has 60mm or more focal length and its main objective is to let you capture a faraway subject with much more details. You can find a number of a telephoto lens from common medium top super telephoto rare. Although the latter is used in sports photography more, it still is not an everyday driver. The 70-200mm, on the other hand, is used more often. Now, you can find either prime telephoto lens or prime. The major impact of telephoto in photography is the blurred background whereas the subject captured seems closer.

Wide Angle Lens

Wide Angle Lens

Wide angle lens is siblings to a prime lens as they too have a fixed focal length. The lens uses 35mm focal length for a wider field of view and captures more of surroundings. The ultra-wide 24mm FL is to wide angle what 24-85mm is too telephoto. This lens lets a camera capture more of the scene, unlike any other lens. The landscape photographers use either 35mm wide or 24mm ultra wide lens for the awe-inspiring photographs we use as wallpapers.

Macro Lens

Macro Lens

For capturing subjects at an almost microscopic level. The macro lens is used for an extreme closeup of the subject, that captures detail-rich images of tiny things like ants or flowers or spiders. The lens brings objects extremely close to the lens in order to make it appear very large in the final image. Photographers also use a macro lens for studio portraits. It is a widespread fact that no other lens can challenge the sharpness and details of a macro lens, and it is justified once you have witnessed the miracle yourself.

Fisheye Lens

Fisheye Lens

If there is any other lens on par with ultra-wide, it is the fisheye. The focal length varies based on the frame like the full frame fisheye lens carries a focal length 15 or 16 mm while the typical fisheye lens is 8mm to 10mm. The captured photos have a 180-degree field of view and appear spherical-ish. Not widely used, the application of the lens is more seen in landscape photography or capturing a panoramic appearing image of a surrounding. However, more recently the photographers have started using it in other photography as well.

Aperture is Yet Another Significant Factor

Aperture is Yet Another Significant Factor

In the market, a number of camera lenses are available for a variety of use. But in all the cases the lenses are understood by two parameters; focal length and the maximum aperture. Short Focal length lens has an aperture between f/1.2 to f/2.8, the larger focal length has an aperture of f/2.8 to f/5.6.

Choosing an ideal lens is important for the nature of photography itself. You can get a good result in any lens, however, you will be missing important details. Once you learn the basics of lenses, it is time for you to get into the action with the right lens.
