Metering method
There are three metering modes available. All three are reflective methods (measuring
the light reflected off various selected parts of the subject according to method) and
are through the lens (TTL). These have the following designations (with their respective
display symbols):
– Centre Weighted
– CentreSpot
– Spot
See under 'Appendix' for details of sensitivity distribution.
Centre Weighted:
Commonly used for ‘average’ light situations where there is no
particular dominance of light or dark areas across the tonal range.
CentreSpot:
Emphasizes the central section of the focusing screen. This provides a bal
anced assessment and is a typical choice where the main subject is in the centre of the
image.
Spot:
The sensitive area is marked by the central spot on the viewfinder screen. Any
parts of the image outside of this area will not affect the exposure reading. This provides
a very accurate measurement of specific tones. Typically used in the zone system and
similar light measuring situations where maximum control is required. Also excellent for
tonal comparison measurements. The spot mode can display ‘zones’ instead of EVs in
the viewfinder display (see
Custom Options #14
).
Selecting metering method
Proceed as follows with the camera in active mode:
1. Press the
EXP
button on the viewfinder.
2. Turn the rear control wheel (in either direction 2a) to successively access the three
choices:
Centre Weighted, Centre Spot
and
Spot
2b.
3. Press
Save
(
DRIVE
button) to retain the setting.
Exposure method
Exposure can be controlled either manually or by using one of four automatic modes.
These have the following designations on the grip display:
M – Manual
A – Aperture (priority)
S – Shutter (priority)
P – Program
Pv – Program variable
In each mode you can see both the aperture and the shutter speed information on the
grip display and on the viewfinder display.
In manual mode, aperture is set by the front control wheel and the shutter speed by the
rear control wheel unless set otherwise in
Custom Options #27.
In the automatic modes, the aperture and shutter speed settings are controlled by the
camera, either partially or completely according to setting. Within this mode there are
four choices.
(Please see the
Appendix
for
P
and
Pv mode
charts that describe the aperture and shut
ter speed setting combinations.
