2. Generally speaking, in a lens, if the focal length is in the range of 80mm to 300mm, it can be called telephoto lens, and if it exceeds 300mm, it can be called super telephoto lens. In today's digital age, various definitions are different from the traditional ones, so a digital camera with a focal length of more than 200mm, which is equivalent to the international traditional 35mm camera, can be called a telephoto machine. Now there are many digital cameras with a focal length of 350mm or even 432mm, which brings great convenience to people when shooting at a long distance. With the help of telephoto or even ultra-long focal length lens, we can not only shoot distant objects, but also take excellent portrait photos with telephoto and appropriate aperture parameters.
3, and the so-called wide-angle lens is a lens with short focal length and large viewing angle. Generally speaking, a lens with a focal length less than 35mm equivalent to a 135 camera can be regarded as a wide angle, but on a digital camera, it is generally 28mm below 35mm, so in many cases, we are used to calling a digital camera with a focal length less than 28mm a wide angle digital camera.
