Join Ben Long for an in-depth discussion in this video Focal length multipliers, part of Photography Foundations: Lenses.
For more than 70 years, 35mm film was the dominant photographic medium.…Then digital photography came along.…35mm film is still used for some still photography and used a lot for motion…picture photography.…Like a digital sensor, a piece of 35mm film crops a specific sized rectangular…image out of the image circle projected by a lens.…After 70 years of using 35mm film people got used to specific focal lengths…having specific fields of view.…So photographers became accustomed to the idea that a 50mm lens was a normal lens,…because when used with 35mm film a 50mm lens has roughly the same field of…view as the human eye.…
Anything longer than 50mm is telephoto. Anything shorter is wide-angle.…With 35mm film a 28mm lens is pretty wide.…A 16 or 24 millimeter lens is ultra-wide.…Conversely, 300mm has a good amount of telephoto power and 600mm puts you in the…realm of serious surveillance.…Most digital cameras had image sensors that are smaller than a piece of 35mm film.…That means they crop a narrower rectangle from the circle projected by the lens.…
