FILTERS19
Make sure the filter size matches the lens, then screw the filter onto the front of the lens.
✍Memo:
•The compatible filter size for all the lenses are listed on pages
•Filters cannot be mounted on the DA
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.
Attaching the 30.5mm filter to the DA 40mm f/2.8 Limited lens
Normally, you attach the 49mm filter to the front of the lens. But as shown in the diagram, you can also screw on a 30.5mm filter to the back of the dedicated hood.
