Canon 518 SV - Manual (Page 19)

Since the viewfinder of Auto Zoom 518 SV is of the singie lens
reflex type, the exact picture image to be fiimed can be seen
without any parallax. This enabies you to compose the scene within
the maximum field-of-view.
Focusing
Adjust the focus by turning the focusing ring so that the subject
can be seen most ciearly through the microprism screen range­
finder built into the center of the viewfinder.
The aiigned image can be seen more accurately and easily the
longer the focal length of the lens. Therefore, first focus at max­
imum magnification (telephoto) and then return to the desired
magnification. The focal point does not change by zooming.

When you wish to zoom or want to decide the size of the subject
in the picture area, turn the zoom lens by pressing the power zoom
buttons or using the manual zoom knob. The image seen through
the viewfinder will change in magnification and the field-of-view
will also change.
When zooming is performed during shooting, any desired zooming
effect can be reproduced on the film.
Power Zooming
Press the power zoom buttons for smooth and regulated zoom
effects. Zooming towards telephoto is obtained by pressing the
“T” button and towards wide-angle by pressing the “W” button.
The necessary zooming time for the entire range is approximately
six seconds.
Manual Zooming
When you wish to zoom faster or slower than any regular speed,
turn the zoom lens by using the manual zoom knob.
