What are the focal lengths, types of lenses, and characteristics of each?
Focal length reflects the change in the angle of view.
Generally , they are divided into...
Super telephoto, no more than 300. Nowadays, everyone is greedy and thinks 400 or more is considered a super telephoto. Super telephoto lenses for civilian use are typically 600mm or 800mm, which are essentially fixed focal lengths, and zooms are particularly heavy. Typically, 1200mm is the limit, and if it is longer, it is rarely used by civilians.
The key difference between different focal lengths is the angle of view. This difference in viewing angle will result in changes in the sense of spatial compression.
