To zoom in or out, look through the viewfinder and slide the focusing ring
back and forth until the desired composition is framed on the focusing
screen.
As the ring is pushed forward for shorter focal lengths, a five-
position scale is uncovered on the lens barrel to show which focal length
the lens is set for. To preset the lens for a specific focal length, align the
edge of the focusing ring with the top edge of the digits.

DEPTH-OF-FIELD SCALE
A group of colored lines, curving out toward the front of the lens, are
engraved on the lens barrel. To find the depth of field at a particular focal
length and aperture, first compose and focus the lens on the subject. Then
check the numbers on the distance scale opposite the colored lines to find
the depth of field at that aperture. The colors of the pairs of lines
correspond to different lens apertures. The continuous curved lines of the
depth-of-field scale give the reading at any focal length. You can also
observe the depth of field through the viewfinder by pressing the
depth-of-field preview button on the camera.
INFRARED PHOTOGRAPHY E
In infrared photography, the plane of sharpest focus is slightly more distant
than the one produced by visible light. As a rule of thumb, you can compen-
sate for shift in focus by referring to the curved red infrared line engraved
between the depth-of-field index lines on the lens barrel.
After sharply focusing the subject through the viewfinder, check the focused
distance and turn the focusing ring to the left until the prefocused distance
figure is aligned with the infrared compensation line. Then attach the filter
to the lens and take the picture.
