Filters and Adjusting of Film Speed
Filters
Various types of filters (58mm screw-in type) for Canon Zoom DS-8
are available.
Film Speed Adjustment
When using filters on the taking lens and/or the variable shutter
control lever is shifted other than to the “OPEN” position, the film
speed settings should be adjusted.
Turn the film speed dial and match the ASA/DIN of the film being
used with the proper orange index according to the exposure factor
of the filter and the position of the variable shutter control lever.
For example, when the ND 4 filter is used, the ASA/DIN figure should
be set at the orange index of “4”. And when the ND 4 filter is used
and the variable shutter control lever is set at “2“, the ASA/DIN
figure should be set at the orange index of “8’’ (i.e., 4x2 = 8).
■ Be sure to readjust the setting whenever detaching or replacing
a filter with a different exposure factor.
■ The exposure factors with respective filming speeds do not couple
to the following ASA/DIN film speeds. If the film speed dial is forci­
bly turned the filming speed selector will move and settings cannot
be properly made.
