PROGRAMMED AUTO EXPOSURE MODE -AUTO MULTI-PROGRAM Auto Multi-Program automatically sets the best combination of
shutter speed and lens aperture, making
it
the easiest exposure
mode to use.
Because lenses of different focal length handle differently
at
slow shutter speeds, picture sharpness varies with the shutter
speed used. The slowest shutter speed recommended for any
lens when hand-holding the camera
is
1/(focal length) of the
lens. With a 60mm lens, for example, use 1/60
sec.
as the slow-
est hand-held speed. Keep in mind, however, that 1/30 sec.
is
the lowest recommended shutter speed for blur-free hand-held
shooting. The exposure program line for N5005's Auto Multi-
Program varies according to the focal length and maximum
aperture of the lens. The following chart shows how the possi-
bility of picture blur
is
reduced by avoiding slower shutter
speeds.

The
EV
(exposure value) charts demonstrate the differences
among program lines of various lenses. Follow either colored
line to where
it
intersects a diagonal line. This shows the com-
bination of aperture (vertical line) and shutter speed (horizontal
line) that will automatically be selected at each
EV
brightness
level.
