Mamiya 645 PRO TL Manual Do Utilizador

Depth of field is defined as the zone

of sharpness before and behind the

plane of focus. It depends on camera

subject/distance, focal length of lens,
aperture setting and distance the lens

is focused at.

In addition to visual observation, the
Depth of Field can be determined by

using the Depth of Field Scale on

each lens. f/stop numbers appear on

both the right and left side of the red
index mark in the center of the scale

ring. Simply read the figures which

appear above the f/stop numbers on
the distance scale of the lens.

For example, with the 80mm f/2.8N
lens focused at 3m and the aperture

set at f/22, the depth of field scale

indicates that the zone of sharp focus

will extend from about 2m to 6m.
