Controlling How the Camera Sets Exposure
77
P: Auto Multi Program
In this mode, the camera automatically adjusts shutter speed and aperture
according to a built-in program (see below) for optimal exposure in most
situations. This mode is recommended for snapshots and other situations in
which you want to leave the camera in charge of shutter speed and aperture.
Adjustments can be made using flexible program, exposure compensation
(
86), and auto exposure bracketing ( 88). Auto multi program is only
available with CPU lenses.
Non-CPU Lenses (Exposure Modes P, S, and A)
Non-CPU lenses can only be used in manual exposure mode ( 82), when aperture can
be adjusted manually using the lens aperture ring. If another exposure mode is selected
when a non-CPU lens is attached, the shutter release will be disabled and a blinking
will appear in the aperture displays in the control panel and viewfinder.
Exposure Program
The exposure program for auto multi program is shown in the following graph (ISO
200):
Aperture
AF 50 mm f/1.4D
AF ED 180 mm f/2.8D
AF-S ED-300 mm f/4D
Shutter speed
The maximum and minimum values for EV vary with sensitivity (ISO equivalency); the
above graph assumes a sensitivity of ISO 200 equivalent. When matrix metering is
used, values over 17
1 /
3
EV are reduced to 17 1 /
3
EV.
