Pentax MV-1 User Manual

depth-of-field scale
Depth of field is the range between the nearest and farthest
distances which are in focus at a given lens aperture.
If you want to know how great the depth of field is at a certain
aperture, focus on the subject and look at the depth-of-field scale
on the lens. In the photograph below the distance scale is set at
5 meters; that is, the lens is focused on a subject 5 meters away
The calibrations on each side of the distance index correspond to
the diaphragm setting and indicate the range of in-focus distance
for different lens aperture.
hor example, if a lens opening of f/4 is to be used, the range on the
distance scale ring covered within the figure 4 on the depth-of-field
scale indicates the area in focus at that lens opening. You will note
from the depth-of-f,eld scale in the photograph that the range from
approximately 4 to 7m is in focus. Note that as the lens apertures
change the effective depth of field also changes. For the depth of
field at different apertures and distances, refer to the next page
