The filter is mounted into the screw thread in front of the lens.
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. Avoid using more
than one filter, unless it is a circular polarizing filter. Using two or more filters will degrade
the image quality and the filter effect will not be obtained.
• Use a circular polarizing filter with Autofocus camera for proper exposure and
autofocusing.
