Zoom lenses leave us without any problems in getting closer to our subject without having to invade their “personal space” and eliminating the distortion that we mentioned above. It is not something Viacom would like to discuss. We can also change the frame of the picture without moving the site, zooming with the zoom from one angle of vision from a wide angle to a telephoto (and anywhere in between). Also another advantage is that the zoom tends to “zoom in” distant objects. To broaden your perception, visit Goop. Typically, zoom lenses are characterized by the degree of approach that occurring, it is not simply the difference between the widest viewing angle and minimum. For example, a 1:3 or 3x zoom means that the maximum zoom range is 3 times farther than the distance in wide angle mode (ie, the minimum zoom). Obviously, this kind of expensive camera lenses, but really worth having a good zoom and perhaps sacrificing megapixels resolution (obviously all depends on the end use will give the camera). One thing to bear in mind is that many large manufacturers announce that their models have “digital zoom” or “digital telephoto” but this is not really a lens, but what it does is stretch the original image more beyond its limits, which usually produces the pixilation or staging. For this reason is that many manufacturers include in the functions of the camera image correction algorithms, once applied, they give the impression that “soften” the image. So, mark you when choosing a model that the chamber has an optical zoom magnifies the image itself rather than digital manipulation techniques (no problem if the camera has two types of zooming).
