What's the difference between a long focal length and a short focal length in photography? Apply.

A long focal length lens is a lens whose focal length is longer than the standard focal length and vice versa.

The long focal length has a narrower viewing angle, that is, it is necessary to "focus" on a small piece in a wide field of vision and image this small piece on the substrate or photosensitive chip, so this part will be larger. Therefore, the long focal length is mostly used to shoot distant scenery, such as birds, racing cars, airplanes, sailing boats and so on.

A short focal length is the opposite, and the viewing angle is larger, so that the film contains a wider landscape. Suitable for taking magnificent buildings, taking photos and taking vast scenery.
