Shopping for the right lens requires that you have knowledge on a number of things. Below are some of the factors to consider in this venture.
Understanding Lens Aperture and Its Role
Best camera lenses should allow photographers to take pictures in dark places without affecting the quality of the final image. In essence, this is known as the aperture. One will come across lenses with maximum apertures indicated. It is important to select one whose aperture fits your shooting conditions. The smaller the size of the aperture, the more light gets to the sensor. This means that one can get high quality photos even without natural light.
Hypothetically, the finest aperture size should be one with a figure of 1. However, in practice, the most unrivaled aperture sizes begin from 1.2. All the same, most consumers find aperture numbers ranging from 2.4 to 3.2, satisfactory.
Select the focal length of choiceThis should probably be one of the most basic things to consider when shopping for an additional lens for your camera. In most cases, manufacturers give the focal length size in millimeters. They also specify whether the lens one is interested is telephoto or it shoots at wide angle. It is therefore vital to know the pros and cons of both.
For instance, telephoto lenses can zoom in to objects that are far away. They are equally preferred for taking portrait photos since they do not distort the proportions of the face. On the other hand, they are more likely to give blurred backgrounds. Their depth of field is less in comparison to their wide angle counterparts. In addition, they have low brightness, a factor that results in the blurry backgrounds.
On the other hand, wide-angle lenses are preferred to use when shooting nature and landscapes. They are better than the telephotos both in depth of field and brightness. Photos of nature and landscapes should look as natural as possible for them to maintain the scenic touch. These lenses are also smaller in size, which makes them easy to carry along. On the down side, one can confidently say that these are not ideal lenses when taking photos of people, more so portraits.
Choosing between Fixed and Zoom
For a number of professional photographers, they would prefer zoom lenses. These lenses allow one to achieve various focal lengths using the same gadget. That is cost effective as one is not forced to buy several lenses.
However, fixed lenses have their own advantages. They are small, light and easy to carry. In addition, their brightness is better than their zoom counterparts.
