69. Part 1: The Lens Lenses are defined by focal length
(measured in millimeters) and by speed (measured in f/stops). Speed
is determined by the largest opening of the aperture. Lenses with
larger maximum aperture openings are considered faster than lenses
with smaller maximum apertures. Faster lenses can shoot under lower
light conditions. Zoom lenses can have a variable speed, i.e. be
faster at 18mm than at 55mm.

of light that enters the camera, and determines field (angle) of
