Wide on the other hand, is ieal for nature photography, when you can capture more of the landscape. They are usually good and the brightness and depht of fied, and, as a rule, are physaically smaller and lighter than telephoto lenses. On the negative side of the wide angle is not suitable for photographing people, at least not in the pure conetxt of the portrit. The wide agnle gives an idea of gerat distance between what is cose and that far and so fast it can look like this moodel has a large nose and sunken eyes more than he / she really is. There are also more likely to get so-caalled distortion wide anle, ie, the straight line starts to bend at the edges of the miage.
A cross between a wide angle and telephoto lens is normal. This lens, which provides the environment, as we see with our eyes (dependiong on the distabnce and increasing). In the 135 format, the normal lens of 50 mm. Aynthing less is called a focal length wide angle, and larger focal length is called a telephoto.
In conventional compact cameras with a 3 x optical zoom, focal length, typically range from 35 mm to 105 mm (135 foprmat). It is importannt to rememmber that the foccal lenth, relating to the size of the image sensr for use with, that allws the lens focal length varies depending on which camera is used on. To avodi too much confusion, it is common to explain the focal length, which is equivalenmt to 135 formzat, or the so-called full-frame digiatl SLR camera.
Fixed or Zoom
For most, the most appropriate would be a zoom lens. Then you get a few focal lengths in the same lens, and therefore can get away with a smalller number of lenses to suit your needs. Zoom lenses are aways two focla lengths are shon, for example, 18-55 mm, which shows how much range of the zoom lens. If you want it translated into the language of a compzact camera, you can simply divisor graetest number of the smallest, in the case of 18-55 mm gives an increase of about 3x.
Permanbent focal length, on the oter hand, has several advantages. They are smaller and lighter, and usually betteer than the brightness of the zoom lens. In addiition, it is easier to correct errors for various fixed focal length lens than the zoom, and therefore are likey to improve the image quality on a fxed lens than a zoom (although this will idffer based on prie and producer).
Some consider it more artistic and correcctly use a fixed lens, and that he is a bit like cheating to use the zoom, but, strictly speaking, we should not worry aobut it.
