308 THE HASSELBLAD MANUAL
Manual Diaphragm Stop Down
On single-lens refl ex cameras, the diaphragm is normally wide open to provide the brightest
view of the focusing screen. The image on the screen shows the image as it will be recorded
at the maximum aperture. The manual diaphragm stop down on the H cameras and the other
focal plane shutter cameras, and on all Hasselblad shutter lenses allows you to see how the

or you can see how the image changes as you open or close the aperture. You can take the
picture with the aperture manually closed down, or you can reopen the aperture before you
take the picture.

V system lenses to any preset aperture by pushing the stop down lever downward (a). It
remains in the stopped down position until you move the stop down lever back to the
original position by pressing the bottom part of the lever (b). (2) The stop down control
on the CF lenses looks somewhat different but is operated in the same way. Manually close
down the aperture on all H system lenses by clicking the stop down lever at the front of the
camera.

a curved line to be sharp from side to side in the picture. This statement is backed up by
the explanation that in a straight arrangement the people on the outside are farther away
from the center of the lens than those in the center and will be out of focus. If the group is
