Depth-of-field preview
Depth of field at any aperture and focusing
distance can be previewed visually by pushing
the stop-down button all the way in. This will
stop the diaphragm down to the aperture
corresponding to the f-number preset on the
aperture ring, allowing you to see through the
viewfinder how much of the subject is accept¬
ably sharp,
Depth-of-field scale
The near and far limits of acceptable sharp¬
ness can be determined from the depth-of-field
scale on the lens barrel. With the lens focused at
a given point, the image will be in satisfactory
focus from the nearer value to the farther value
on the distance scale indicated by the depth-of-
fleld scale marks for the aperture to be used
(see pictures at left).

Infrared index
For proper focus when making pictures with
infrared radiation, first focus your subject with
visible light as described above, then attach a
red filter and turn the focusing ring to the right
to align the point of proper focus on the
distance scale with the index designated with
small red dot (earlier MD lenses have an ''R"
instead of a dot) in the depth-of-field scale.
When making color pictures, follow the manu¬
facturer's recommendations to set focus.
Film-plane index
The symbol on the camera top plate to the
right of the viewfinder indicates the exact plane
occupied by the film in the camera. This can be
used to measure distance from subject to film.
