The focal length determines the size of the field of view Angle. The focal length value is small, the field of view Angle is large, and the observed range is large, but the distant object is not clearly resolved.Large focal length, small field of view Angle, small scope of observation, as long as the appropriate focal length selection, even distant objects can be clearly seen.Since the focal length and the field of view are one-to-one correspondence, a certain focal length means a certain field of view. Therefore, when selecting the focal length of the lens, it is necessary to fully consider whether it is important to observe the detail or to have a large observation range. If you want to see the detail, you should choose the lens with a long focal length.If you're looking at a large scene up close, choose a wide-angle lens with a small focal length.
