Depth of Field
There are two ways to check depth of field. One is by using the depth-of-field scale
on the lens. This is a scale of f/stops repeated on each side of the distance index.
on the lens. This is a scale of f/stops repeated on each side of the distance index.
1. First focus. Then press the shutter button halfway and note to which f/stop
the meter needle points in the viewfinder. Find the two f/stops on the depth-
of-field scale which correspond to that number.
of-field scale which correspond to that number.
2. Draw imaginary lines from those two numbers to the distance scale. The
effective depth of field lies between those two distances.
