Telephoto lenses have sizes above 70 mm. This type of lens is very popular in wildlife photography, sports, journalism, as well as shooting of objects that cannot be approached. The distinctive feature of a telephoto lens is that it is able to make distant objects appear close. Telephoto lenses can also be used to take pictures secretly without being noticed by the object. Another distinctive feature of this lens is that the focal length is far away so that the depth of field is thin. Such conditions make areas that are not in focus in the image very blurry. Therefore, telephoto lenses are also suitable for shooting profiles.
The weakness of this lens is that it is very large in size. The large size makes the lens heavy, and the camera becomes difficult to stabilize. If the camera is not stable, the image will be blurry, aka not sharp. In order for the camera to remain stable, we need the help of a tripod. Therefore, choose a telephoto lens that is equipped with image stabilization technology to reduce the effects of shake on the image.
