Good lenses are expensive, so when buying, you want to eventually acquire quality, beauty, opportunities in the form of sensitivity parameters, sharpness. There are many criteria by which his choice should take place. Basically, it all depends on the genre of photography and the level of professionalism. Among the main points are the following.About the differences between expensive and cheap lenses Despite the fact that even budget optics in their quality and resolution are sometimes little inferior to professional, the difference between these categories of lenses in the final result is simple - in artistry and overall strong impression of the picture. Its character depends on the quality of the glass in the lens, the features of the optical system, the shape of the aperture. It is worth choosing modern lens models, the quality of which has increased markedly recently.Do not use super-zoom lenses, because these are universal devices that change the angle of the field of view up to a powerful one. The disadvantages include a short operating range of focal lengths, shape changes and chromatic aberrations (colored shadows around contrasting objects formed due to color dispersion), a small aperture at the long end (in connection with which it is necessary to raise the ISO several times). These lenses are not technically perfect, which affects the quality of the frame.A 5-8-fold zoom is suitable for traveling. Such devices are lightweight, compact and convenient, and are also found in all systems (Canon, Nikon). This travel zoom makes it possible to photograph the near and far plans.Other important characteristics We need a high-power lens when shooting indoors. It is especially suitable for working in a room with natural light (near the window). These are quite expensive, but there are cheap alternatives, for example, high-power lenses with an entry-level focal length.For portrait photography, you need to choose a high-speed fix. Fixes with a distance of 50 mm are most optimal for portrait photography.For landscape photography, the best choice is a wide-angle lens. There are many of these: an ultra-wide-angle device with an equivalent focal length of 16 mm is suitable for amateurs. The device perfectly conveys a sense of space, the effect of perspective, stretching objects in the foreground and pushing back smaller objects. For the natural transmission of a composition with normal proportions, a focal length of 35-40 mm is suitable.The autofocus option is available in almost all modern lenses, but there are differences in characteristics, in particular in the type of drive, which determines the noise level during operation. Some photographers use manual focus adjustment, but it hardly makes sense for beginners to give up comfort.Devices with a fixed focal length help the photographer to "fill his hand" and approach the composition more scrupulously. The optimal lens for every day is one with a focus distance of 35-40 mm.
