Make sure the filter size matches the lens and then attach the filter onto the lens.
2. Precaution on filters
• Since the filter becomes a part of the optics when attached on the lens, handle it in the
same way you handle the lens with care to dust, dirt and scratches. Normally, attaching
two or more filters on a lens is not recommended. However, attaching a circular
polarizing filter and another filter would not be a problem.
• Use a circular polarizing filter with Autofocus camera for proper exposure and
autofocusing.
