Understanding Focal Length

Published by:  Photoxels
Tutorial Preview:

We usually categorize lenses as having a wide-angle, normal or telephoto focal length. A normal 35mm lens covers a 24x36mm film with a field of view that corresponds approximately to our normal vision; a lens with a focal length of 50mm (55mm is also popular) is considered as normal. Any lens with a focal length less than 50mm (or 55mm) can be considered as wide-angle; any lens with a focal length greater than 50mm (or 55mm) can be considered as telephoto. A zoom lens offers a range of focal lengths.
