DEPTH OF FIELD

Depth of field is the area of acceptable sharpness

in front of and behind the subject in focus. As you

get closer to your subject or as you open your lens

(e.g. from F16 to F2.8) the depth of field becomes

shallower. By stopping your lens down (e.g. from

F2.8 to F16) or getting farther away from your

subject this depth of field can be increased.

The table below shows that when the camera-to-

subject distance is 3m, the depth of field at F16

ranges from 1.93m to 6.93m.

As you press the preview button, looking through

the viewfinder, you can ascertain the actual depth

of field.

Circle of least confusion 1/30mm

The double series of numbers engraved on the

depth of field scale represent F stops: F4, F8 and

F16. Once you have focused on your subject, all

objects within the distance range indicated on the

lens distance scale between the marks for the F/

stop

you

have

selected

will

have

acceptable

sharp-

ness.

instruction manual.
