Circular polarizing filters and vignetting
Circular polarizing filters are thicker than regular filters. Depending on the lens that is mounted and the
shooting conditions, vignetting may occur in the four corners of the image. Refer to the “Compatibility
table for PENTAX circular polarizing filters” on the following page for information on compatibility of the
PENTAX circular polarizing filters (currently not available) with various lenses. There are two types of
PENTAX circular polarizing filters. The A type (on the left in the diagram below) and the B type (on the
right in the diagram below). The B type filter is thinner than the A type filter.
