We have different lenses on the cameras - a shorter lens to get a two- or three-shot, a longer lens to punch in for a close-up.

This works fine with short focal-length lenses at moderate distances, and it's great for street shooting.

With a shorter lens, it would have been impossible to see the urchin.

It also gets around another limitation of point-and-shoots: the inability to change to a longer or shorter lens.

It's also not surprising that pros photograph "on the street" with short focal-length lenses, 35 millimeters at most.

Conversely, a shorter lens, or a smaller aperture, will result in more of the image being in focus.

This is a wide-angle series of lenses, which allow greater enlargements and use of shorter focal-length lenses than would otherwise be possible.

Ackers called down to Gibbs, "You got a short lens on that thing-a-majig?"

They appear as sets of short, parallel, lenses on the surface of a rock.

For APS-C any lens shorter than 15 mm is considered ultra wide angle.
