The presence of a lens in the camera is taken for granted by us. And this is not surprising, how can a camera be without a lens? It is a complex mechanism. In view of this, in order to achieve high-quality shooting, you need to correctly calculate the lens.
Instructions
Step 1
Calculate the lens based on its technical features. Today, there are many types of lenses, among which the most common are: fisheye, wide-angle, whale, ordinary (normal) lens, portrait lens, macro lens and telephoto lens.
Step 2
If your attention is riveted by a fisheye lens, pay attention to the peculiarity of this device. The lenses of this group are characterized by a wide angle of coverage of the filmed area: in fact, these devices are out of competition on the diagonal of the "cropped" frame. Among the representatives of this group there are lenses with a focal length of 4.5 mm.
Step 3
Pay attention to the wide-angle lens: its angle of view is 90 degrees. Having only one drawback in comparison with the “fish eye” - the viewing angle is half the size, this type of device does not distort the picture. In addition, a wide-angle lens visually "compresses" the picture, making it wide-angle when shooting objects located at close range or at a certain angle, making it easier for your eyes to perceive it.
Step 4
If you opted for a kit lens, take into account the fact that in terms of functionality, the devices of this group are not bad: they can be used to shoot indoor conditions and portraits, for this you just need to correctly adjust the zoom ring. The equivalent focal length of devices in this category is 50 millimeters. In comparison with devices of the "whale" type, "normal" lenses have a lower EGF, in view of this, they are intended primarily for training, and not for professional photography.
Step 5
A macro lens is indispensable when photographing the microcosm. When characterizing devices in this category, such a parameter as "minimum focusing distance" is used: the value of this indicator should be less than 5 centimeters. In contrast to this type of lens, telephoto lenses are used to capture subjects at a distance.
Step 6
Pay attention to portrait lenses. They can be distinguished from other devices by their special value of the equivalent focal length. For portrait lenses, this figure varies between 85-120 mm.
