For Continuous Servo Autofocus, with AF Zoom-Nikkor 35-70mm f/3.3-
f/4.5 lens, new AA-type alkaline-manganese batteries, a shutter speed
of 1/250 sec. or faster, at normal termperature.
•Depends on brightness of available light.
• Continuous framing rates may vary with the autofocus mode
set to Single Servo because the shutter is released only when
the subject is in focus.
• With the autofocus mode set to Continuous Servo, the shutter
will fire when you press the shutter release button, regardless
of focus status. Autofocus will operate in
C
l
mode when re
quired focus adjustment is minimal. However, if considerable
focus adjustment time is necessary, there may not be suffi
cient time between frames for the required adjustment.
• For prolonged shooting at low temperatures, set the film
advance mode to S or C
l
(except with autofocus mode at
Continuous Servo), In these modes, the shutter charging
motor and film advance motor are driven sequentially to save
battery power.
