see by how much darker they are compared to the foreground by
the EV dierence read o the scale (illus 3).
If you have chosen Spot together with Zone display (see ‘Custom
options #14’ for settings and ‘Zone’ in the Appendix for further
information about the zone system.) as well as one of the auto-
matic modes A, S, P or Pv, point the spot marking at an area that
you decide should be a Zone 5 and click the AE-L button (illus 4).
The meter will now display dierent parts of the subject as zone
values (illus 5) in the viewnder display, instead of EV deviations,
as you move the spot marking over the subject. (Included are Lo
and Hi (illus 6)to signify areas beyond the range of the sensor).
Alternatively you can choose to re-classify an area as another zone
and then check the rest of the subject to see how other areas fall
on the zone scale. Do this by following the above procedure and
then turning the rear control wheel until you see the new desired
zone value in the viewnder display. You will also see the new
exposure that will now produce that new zone. For example, you
might have measured a rock at zone 5 but wish to make it darker.
By moving the rear control wheel you could re-classify it as zone
4. You will then be able to see, for example, whether white clouds
are now falling within the exposure range by their new Zone clas-
sication.
Alternatively, you can also pre-set the initial zone reading in order
to save time and eort where there is no freely available ‘zone 5’
subject for light measuring. For example, you might be on a san-
dy beach where you know that sand is normally classied as zone
6. You can pre-programme the zone placement by holding down
the AE-L button while choosing the new zone value and turning
the front control wheel until zone 6 appears. All new placements
will then be zone 6.
Exposurecompensation/QuickAdjust
The exposure compensation facility, for both manual and auto-
matic modes can be set from -5 to +5 EV, in 1/3, 1 or 1/2 EV incre-
ments (Custom Option #3) and is visible above the scale in the
viewnder and as a ± symbol on the grip display.
The quickest way to make an adjustment in auto-exposure mode
is use the rear control wheel.
To make a temporary compensation setting in an auto-expo-
sure mode using the Quick Adjust facility:
a) Select chosen auto exposure mode.
b) Turn the rear control wheel to select the chosen amount of
compensation.
The amount is displayed in the viewnder as both an EV g-
ure complete with a ‘minus’ or ‘plus’ prex (A in illustration 3),
and as a marker above a ‘minus’ to ‘plus’ scale (B in illustra-
tion 3).
Default settings provide 1/3 EV compensation and an immediate
clearing of the setting after capture.
However, in Custom Options #3 you can select 1/3, 1 or 1/2 EV
increment changes, in Custom Options #23 you can choose to re-
tain the setting after capture and in Custom Options #17 you can
deactivate the facility.
