If you want to click good pictures then you need to be choosy in picking up a camera lens. However, it is not an easy thing to do as the market is flooded with varied options of camera lenses. Considering this thing here some of the points have been highlighted that will help you in selecting the right camera lens. Scroll down to learn more about these points.

Know more about Aperture

With respect to your requirements, you must select the lens. That is why you must not ignore the aperture number which tells you in how much darker conditions you can click a picture with a lens. If your aperture number is less then it means more light can enter a camera. In theory, the best aperture is 1 but in reality, you get maximum aperture at around f/1.2.

Generally, users opt for a camera lens with an aperture number ranging from f/2.4 to f/3.2. As far as zoom lenses are concerned, you can find two aperture numbers, where the smaller aperture shows how much the amount of light you will be getting with the widest angle, and the larger one gives you an idea the amount of light you can get at the maximum zoom.

Choose the right Focal Length

The next point to consider is the focal length of any of the camera lenses. This length is displayed in millimeters and tells you whether the lens you are selecting is a wide-angle one or telephoto.

A telephoto is a good option for those who want to click pictures of subjects which are far and you want to bring them naturally closer.  Even this type of lens is preferred for portraiture because of its ability to protect the facial proportions. To get a blurred background you can opt for a telephoto lens as it has less depth of field in comparison to the wide-angle lenses. However, this type of camera lens has usually lower brightness. That is why it is vulnerable to blurriness during the shoot in case of any camera shake. If you are planning for nature photography, then you can opt for a wide camera lens as it is good in brightness and depth of field.

Have an understanding of Color Refractive Correction

Choosing a lens is an arduous task and so is making a lens. One of the challenges that many lens manufacturers face is that different colors of light bend differently while passing through the lens. This is instrumental in a color shift at the edges of the photo and to remove this drawback, low dispersion glass is used. You are advised to check whether the lens is accompanied with a low dispersion glass and if yes then of which type.


If you want to select a camera lens that fits your needs and requirements then make sure you check all the aforementioned points of different types of camera lenses. Only then you will be able to make the right decision.
