Precaution on filters
• Since a filter becomes a part of the optical system when attached to the lens, handle it
with due care to protect it from dust, dirt and scratches. Normally, attaching two or more
filters on a lens does more harm than good. However, attaching a circular polarizing filter
and another filter is not a problem.
