How to Choose a Lens for Your DSLR or Mirrorless Camera?

Anyone who loves photography knows the importance of a DSLR or mirrorless camera and its lens. The lens is always crucial in deciding the quality of photos or videos you click with it.

Choosing the right lens is not an easy job. One needs to factor in multiple things like the sharpness, prime or zoom, distortion, speed, and obviously the price of the lens as it’s an expensive thing.

All cameras are accompanied with a kit lens, which is generally a zoom in the 24-70mm range equivalent to 35mm. The kit lenses, however, are generally useless if you need to click in low light. Also, their quality is not that great, which results in a mediocre image. Thus, if you are serious about photography, you need to buy some additional lenses.

While buying the lens separately, you should keep the following things in mind.

Type of Clicks You Like to Do:

Unless you want to specialise in a particular type of photography, a versatile, wide focal-range zoom is the best bet for most of the people. This is because the zoom lens offers a wide range of focal lengths. The basic kit lens has 3x zoom, but you can always go for super zooms, which are 7x and 12x.

  • Those who like to be a portrait photographer, however, require a prime or fixed 50-85mm fixed (prime) lens as it flatters the human face the best. As the name suggests, the fixed lens offers one fixed focal length.
  • If you are a product photographer, then going for a macro lens is recommended.
  • Those who love to click landscapes and architectural structures will require to have both wide-angle zoom and fixed lenses.
  • Many people are interested in clicking wildlife, which requires a large, relatively fast telephoto (tele) fixed or zoom lens. The same lens is required if you are a sports shooter.
  • You might sometimes need to shoot in low light and for that normal lens is not the right choice. To get the best result, you should have a fast lens of f/2.8 or lower and with stabilization.
  • The video shooters also need to factor in many other things while buying the lenses. This includes manual focus, parfocal qualities and focus breathing.

Prime vs. Zoom

There’s enough mention of prime and zoom, which must be making you curious about knowing more about them. Well, Zoom is a versatile lens where you can frame the subjects easily without moving. The prime or fixed, on the other hand, has better optics and speed, which is beneficial in low-light performance. This is because zoom lenses have optical compromises, while prime doesn’t.


The lenses are often designed keeping in mind the specific brands and sensor sizes. The lenses for full-frame cameras are very expensive because of more glass in it. It is always better to choose the lenses that are made for the brand of camera you own.

Buying a lens requires a lot of research taking into account multiple factors and one must do this research to buy the right lens.
