Operating the H Cameras for Digital and Film Photography 69
avoids longer shutter speeds for longer focal length lenses. This is the recommended setting
for exposure automation if you work with different focal length lenses. The P and Pv modes
should be used only with the camera set for CentreWeight or CentreSpot metering.
Shutter Speed Priority (Shutter Pr) or (S) Mode The electronically controlled shutter speed range of the
central shutter in the H camera lenses is from
1
/
800
second to 18 hours, including B and T
modes. Shutter speeds are indicated on the display and in the viewfi nder with an “s” when the
speeds are longer than one second (2s means two seconds); for fractions of a second there is
no “s” (30 means
1
/
30
second).
In the Shutter Priority mode, you select the desired shutter speed by turning the front
control wheel. The camera selects the aperture that provides the correct exposure for the
metered area. Shutter Speed Priority is the recommended mode when you are photographing
moving subjects, where the shutter speed determines how moving subjects are recorded in
the camera. You may also want to consider Shutter Priority for handheld photography, which
gives you the opportunity to set a shutter speed that is short enough to reduce or eliminate
blur caused by camera motion. Such shutter speeds can be relatively long because the H cam-
era is beautifully designed for handheld work, providing good camera steadiness at relatively
long shutter speeds. I have obtained pictures with beautiful sharpness at shutter speeds that
I have not dared to use for years, such as
1
/
30
second and even
1
/
20
second with an 80 or
110 mm lens.
Aperture Priority (Aperture Pr) or (A) Mode Because the depth-of-fi eld range must be considered in many
images, Aperture Priority (A) mode is a logical approach for most photography. The A mode
allows you to preset the aperture to a value that produces the desired depth-of-fi eld. You
set the desired lens aperture by turning the front control wheel. The camera then selects
the appropriate shutter speed. Aperture Pr mode is also a good choice because the camera
sets the shutter speeds much more accurately than the
1
/
2
or
1
/
3
increments possible in Manual
mode.
With the function and operation of the automatic exposure modes so beautifully
designed, I personally see no good reason for using the Manual mode. It does, however, exist
in the camera. When working in the Aperture Priority mode, I suggest that you always check
the set shutter speed before releasing the shutter. This is especially recommended in hand-
held photography making certain that the set speed is short enough for possible camera
movement.
Manual Exposure Mode (M) In the Manual mode, you set the aperture by turning the front control
wheel, and you set the shutter speed by turning the rear control wheel. For correct exposure,
you turn either the front or the rear wheel (or both) until the pointer over the exposure scale
in the fi nder is positioned above the central index. The deviations to the left or right are indi-
cated in
1

EV values on the scale. In the Manual mode, aperture and shutter speed settings
are and remain locked.
