Characteristics, tendencies and application of
variable automatic program mode
a) Preset shutter speeds between 4s and 1/15 s:
Program for depth of field
S tendency toward stopping down the lens
while keeping shutter speeds low
S especially suitable for: good lighting
conditions, short focal lengths, stationary
subjects
S caution: beware of increased danger of
camera shake in poor light.
b) Preset shutter speed 1/30 s:
normal program
S especially suited for normal scenes and light
conditions
S focal lengths between 35mm and 90mm
c) Preset shutter speed 1/60 s to 1/2000 s:
program for action shots
S tendency towards higher shutter speeds
(shorter exposure times) with larger
apertures - less depth of field
S especially suitable in poor light, longer focal
lengths and moving subjects
S caution: less depth of field
Rule of thumb: to avoid camera shake with hand-
held exposures as much as possible, set a shutter
speed that numerically at least equals the 1/f-
value (f= focal length in mm), i.e. the lens's focal
length. For instance, when using a 180mm lens,
choose shutter speeds faster than 1/180 s, e.g. set
the shutter speed to dial to "250" (1/250 s).
