Pentax DA 15mm F4 ED AL Limited 操作指南

Mount the filter into the screw thread in front of the lens.

✍

• The compatible filter size for all the lenses are listed on pages 22-23. 

• 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.
