Shutter-Speed Dial - Nikon FM3A Instruction Manual

Shutter-Speed Dial

A (Aperture-Priority Auto Exposure mode)
Once you make the aperture setting, the camera automatically selects the appropriate shut-
ter speed (stepless control). This is the simplest shooting mode with this camera. (
Tips
Locking and releasing the shutter-speed dial:
Once you set the shutter-speed dial to "A," the dial is locked to prevent inadvert-
ent changes.
... To move the dial to another position, rotate the dial while holding down the
auto-lock release button at the center of the dial.
1 to 1/4000 second (Manual mode)
In Manual mode, you can set both the shutter speed and aperture manually to create
various creative photographic effects. (
B (Bulb mode)
In this mode, the shutter stays open as long as the shutter-release button is depressed. Use
this function when shooting scenes that require extended exposure (e.g., night time stars,
etc.). For very long exposures, use a tripod, and instead of holding the shutter-release button
down with your finger, you can lock the shutter release open by using the AR-3 cable release
(sold separately), to take steady, long-exposure shots without worrying about "camera shake."
• You cannot use intermediate positions between shutter-speed dial clicks.
• In B (Bulb) mode, the shutter operation is performed mechanically (not electroni-
cally). However, a very small amount of battery power may be drained. Therefore,
we recommend you remove the battery to save the battery power when you plan to
take many pictures using B mode.

• Depending on the conditions and your
intention of shooting, align the shutter-
speed index to the figures or marks on
the shutter-speed dial. You may choose

modes:
