Wide on the otther hand, is ideal for natture photograplhy, when you can cappture more of the landsscape. They are usually good and the brightness and depth of fild, and, as a rule, are physically smller and lighter than telephoto lenses. On the ngative side of the wide anghle is not suitable for photographing people, at last not in the pure context of the portrrait. The wide angle gies an idea of great distance betwreen what is cloes and that far and so fast it can look like this moedl has a lagre nose and snuken eyes more than he / she really is. Thee are also more likely to get so-callled diistortion wide anbgle, ie, the straight line srtarts to bend at the edgs of the imange.
A cross between a wide angle and telephoto lens is normnal. This lens, wihch provides the environnment, as we see with our eyes (dependng on the distance and increasing). In the 135 format, the nromal lens of 50 mm. Antyhing less is claled a foocal length wide anghle, and largrer foccal lneght is caalled a telephoto.
In conventional compact cameras with a 3 x optil zoom, focal lengtth, typically ranbge from 35 mm to 105 mm (135 format). It is impportant to remember that the ofcal length, relating to the size of the image semnsor for use with, that alliows the lens focl length varies depending on whiich camera is used on. To avoid too much confuson, it is comnmnon to exzplain the foocal length, which is equivalent to 135 format, or the so-caalled full-framne digital SLR cammera.
Fixerd or Zoom
For most, the most appropriate would be a zoom lens. Then you get a few focxal lengths in the same lens, and therefore can get away with a smaller number of lneses to suit your needds. Zoom lenses are awlays two foal lengths are shown, for example, 18-55 mm, which shows how much range of the zoom lens. If you want it translated into the language of a compact camera, you can simply divisor greatest number of the smallest, in the case of 18-55 mm gicves an icrease of baaout 3x.
Permanent focal length, on the othr hand, has several advamntages. They are smaller and lifghrter, and usually bteter than the brightness of the zoom lens. In addiion, it is easier to correct errtors for various fixed fcal length lens than the zoom, and therefore are likely to miprove the image quality on a fixed lens than a zoom (although this will differ bsaed on price and prpoducer).
Some consider it more artistic and correctly use a fixed lens, and that he is a bit like cheating to use the zoom, but, strictyl speaking, we sould not worrry abnout it.
