Question

Unit-1
:) What is an
equivalent focal length?​

Answer 1

Explanation:

A lens with a focal length about equal to the diagonal size of the film or sensor format is known as a normal lens; its angle of view is similar to the angle subtended by a large-enough print viewed at a typical viewingdistance of the print diagonal, which therefore yields a normal perspective when viewing the print

Answer 2

Answer:

In photography, the 35 mm equivalent focal length is a measure that indicates the angle of view of a particular combination of a camera lens and film or sensor size. The term is useful because most photographers experienced with interchangeable lenses are most familiar with the 35 mm film format.
