What is the perspective size of the photographic lens?
The viewing angle of photographic lens is mainly determined by the focal length, and different focal lengths correspond to different viewing angle ranges:
wide-angle lens
The focal length is usually below 35mm, and the viewing angle can reach 60-118 degrees, suitable for shooting landscapes, buildings, and performance scenes that require a large depth of field.
Standard lens
The focal length is generally 35-70mm (close to the human eye's perspective), with a viewing angle of about 40-53 degrees, suitable for portrait, daily recording, and documentary photography.
Telephoto lens
Focal length above 70mm, narrow viewing angle (such as 24-32mm), suitable for shooting distant subjects (such as wildlife, sports events), can compress the background and highlight the subject.
