FOCUSING

Because the auxiliary lens

comes necessary. The range
of focus compensation differs
with the auxiliary telephoto
and wide-angle lenses; there-
fore, refer to the distance
conversion scale Of each lens.
After making focus com-
pensation, shoot in the nor-
mal manner. When the auxili-
ary lens is in use, there is no
need for exposure compensa-
tion.

1. To secure focus when the auxiliary telephoto lens is in use, first make precise focus adjustment by
sighting your subject through the finder.
2. After thus securing focus in the normal manner, read the camera-to-subject distance off the distance

scale.

3. If the camera-to-subject distance is, for instance, 3 meters, read the color-coded figure in alignment
with ‘3’ on the distance conversion scale. ‘

4, Since the color-coded figure ‘2’ is in alignment with the figure ‘3’, reset the distance scale of the
camera lens to 2 meters. This re-adjustment of the distance scale accomplishes the necessary focus

compensation.

Distance Conversion Chart

The distance conversion
scale is featured on each
auxiliary lens, but when
more accurate compensat-
ion is required, refer to
the distance conversion
chart.

CAMERA SETTING

PRECAUTIONS

1. For best results, set the aperture at either
£/5.6, f/8 or f/11. Under certain condi-
tions, good results may not be obtained if
the lens opening is adjusted to f/1.7, f/2,
£/4 or f/16.

2. Make sure the filter is removed from the
camera lens before mounting the auxiliary
