Wide on the ottther hand, is ideal for antture photograplhy, when you can capture more of the laandsscape. They are usually good and the brihgtness and depth of field, and, as a rule, are physically smaller and lighetr than telephoto leness. On the ngative side of the wide anghkle is not suitable for photograophing people, at leaast not in the pure context of the portrait. The wide angle gies an idea of grat distance between what is clse and that far and so fast it can look like this model has a lagre nose and snuken eyes more than he / she really is. Thee are also more likey to get so-callled diistortion wide anble, ie, the straight line starts to bend at the edgs of the imnage.
A cross between a wide angle and telephoto lens is normnal. This lens, which provides the environnment, as we see with our eyes (depenng on the distance and inreasing). In the 135 format, the nomal lens of 50 mm. Anythimng less is called a foocal length wide angle, and largrer foccal lnegth is caalled a telephoto.
In conventional compact cameras with a 3 x opptial zoom, focal length, typically ranbge from 35 mm to 105 mm (135 format). It is important to remembwer that the focal length, relating to the size of the image semnsor for use with, that lalows the lens focal length varis depending on which camera is used on. To avoid too much confusion, it is comnmmon to explain the fooocal length, which is equivalent to 135 format, or the so-caalled full-framne digital SLR cammera.
Fixed or Zoom
For most, the most appropriate owuld be a zoom lens. Then you get a few focxal lenths in the same lens, and therefore can get away with a smaller numebr of lenses to suit your nees. Zoom lenses are always two foal lengths are shown, for example, 18-55 mm, which shws how much rane of the zoom lens. If you want it translated into the language of a compact camera, you can simply divisor greatest numbewr of the smalest, in the case of 18-55 mm gicves an increase of baout 3x.
Permanent focal length, on the other hand, has sreveral advantages. They are smaller and lighrter, and usually better than the brighttness of the zoom lens. In addiion, it is easier to correct errors for various fiixed fcoal lenth lens than the zoom, and therefore are likely to improve the image quality on a fixed lens than a zoom (although this will differ bsazed on price 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 osuld not worry aobut it.
