Canon DS-8 - Manual (Page 26)

Focusing
The Canon Zoom DS-8 has a split-image rangefinder built into the
center of the viewfinder. Adjust the focusing ring until the upper
and lower halves of the subject within the center circle of the view­
finder are aligned and seen cleariy. Since the aligned image can be
seen more accurately and easily, first focus at maximum telephoto
focal length and then return to the desired magnification for shoot­
ing. The focal point does not change by zooming.
■ The distance between the focused subject and the film plane can
be checked through the distance scale by drawing out the built-in
lens hood.
Checking the Exposure Indicator
Aim the camera at the subject and check the position of the expo­
sure indicator inside the viewfinder. When you slightly depress the
shutter release button by approximately 1mm, the Electric Eye starts
to operate and the exposure indicator indicates the proper f/stop.
■ The black dots in between indicate f/16, f/8, f/4 and f/2 respec­
tively.
1 If the exposure indicator is pointing inside the range of the f/stop
I scale, you may depress the shutter release button all the way
down and the film will advance.
O If the exposure indicator is pointing to the upper red mark, it
^ means over-exposure, and so an ND (neutrai density) filter must
be attached or the variable shutter control must be adjusted to lower
the light intensity.
3 lf the exposure is pointing to the lower red mark, it means under­
exposure, and so the lighting must be increased.
