On any 35 mm movie digital camera, a 28 mm lens is a wide-angle lens, and a 200 mm lens is an extended-focus lens. The 35 mm equivalent focal size of a selected lens–sensor mixture is the focal size that one would want for a 35 mm movie digicam to obtain the identical angle of view.

The time period is useful as a result of most photographers experienced with interchangeable lenses are most conversant in the 35 mm movie format. Especially outdoors of the “regular lenses”, lens speed additionally tends to correlate with the worth and/or quality of the lens. This is because lenses with larger most apertures require higher care with regard to design, precision of manufacture, particular coatings and quality of glass. At extensive apertures, spherical aberration turns into more vital and must be corrected. Faster telephoto and extensive-angle retrofocus designs tend to be rather more expensive.

Telephoto lenses (which, to be clear, typically embody any focal length above 50mm), additionally trigger what’s referred to as compression distortion. Opposite of a wide-angle lens, this makes objects appear closer collectively, and anything in the background will look massive relative to things within the foreground. You can use this effect to emphasise the density of a crowd in, say, a cross country race, or to make it appear to be you were much closer to that bear than you really have been.
