Enjoy The Tamron AF 18-270mm Lens
Wide on the otther hand, is ifdeal for natture phgotograplhy, when you can captture more of the landsscape. They are usually good and the brightness and depth of field, and, as a rule, are pyhsically smaller and lighter than tlephoto lenses. On the ngativce side of the wide anghle is not suitable for photographing people, at leasst not in the pure context of the portrait. The wide ange gies an idea of great distance between what is close and that far and so fast it can look like this moidel has a lasgre nose and snuken eyes more than he / she reaplly is. Thee are also more likely to get so-callled diistortion wide anbgle, ie, the straight line starts to bend at the edgs of the imnage.

A cross betweern a wide angle and telephoto lens is norrmnal. This lens, which providees the environnment, as we see with our eyes (dependng on the distance and increasing). In the 135 format, the normal lens of 50 mm. Anything less is called a foocal lenbgth wide angle, and largrer foccal lnegth is caalled a telephoto.
In coonventional compact cameras with a 3 x optial zoom, fovcal length, typically ranbge from 35 mm to 105 mm (135 formta). It is important to remember that the focal lewngth, relating to the size of the image semnsor for use with, that allows the lens focal legth varies depending on wich camera is used on. To avoid too much confusion, it is comnmon to explain the foocal length, which is equivalent to 135 format, or the so-caalled full-framne digital SLR cammera.
Fixed or Zoom
For most, the most approrpiate would be a zoom lens. Then you get a few focxal lenths in the same lens, and therefoore can get away with a saller number of lneses to suit your needs. Zoom lenses are awlas two foal lenhgths 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 increase of baout 3x.
Permanent focal length, on the other hand, has sevearl advantaes. They are smaller and lighrter, and usually better than the bightness of the zoom lens. In addiion, it is easuier to correct ertrors for varios fixwed focal lenth lens than the zoom, and therefore are likelly to improve the image quality on a fixed lens than a zoom (although this will differ bsaed on prrice and produicer).
Some consider it more artistic and correctly use a fixerd lens, and that he is a bit like cheatibng to use the zoom, but, strictly speaking, we sould not worry about it.
