Every camera manufacturer offers a wide selection of different lenses and on top of this wide selection there are also many different lenses offered by aftermarket manufacturers. This can make it quite difficult for you to make a well-informed and smart decision when purchasing your lens.
The correct term is actually “objective lens,” but over the years the shortened form “lens” has become prevalent. Simply put, a lens is an aggregated optical system that produces an image of a real-life object. Modern lenses are not made of a single convex lens, but a combination of multiple lenses and mirrors of various curvatures and magnitudes for an optimal result.
One of the most important characteristics of a lens is the focal length. The focal length is defined as the time necessary for an optical lens to focus. Different focal lengths are suitable for different motifs and several different distances from the photographed object. Lenses with a focal length of 18 to 55 millimetres are suitable, for example, for portraits and photographing from short distances. A lens with a focal length of 55 to 250 millimetres is more suitable for photographing from a longer distance. The larger the range of the focal length, the more versatile it is. For those who want to avoid having to switch lenses constantly, a lens with a focal length of 18 to 200 millimetres, for instance, would be suitable.
The lens is the heart of every camera. The lenses are permanently installed on both compact and digital cameras. You can change the lens on a single-lens reflex camera, which makes it quite multifaceted for taking photos. When shopping for lenses, you should make sure that they are compatible with your camera. Of course, lenses produced by your camera’s manufacturer will always fit, but bear in mind that after-market camera accessory manufacturers also offer products which will give good value for money. These lenses just need to have the right connectors for your camera.
In this category we’ll tell you about the operating modes and applications of various lenses and point out the pros and cons. In the end, there is no one perfect lens. Selection of a suitable lens depends heavily on personal preferences, motifs, expectations of the pictures and financial limitations. While a standard lens sold as a complete package with a single-lens reflex camera won’t cost too much, professional models can cost an arm and a leg.
