Pentax SMC -FA manual Screw-in Type Filters, Precaution on filters

Notes :

•Be sure that the PL filter window cap is in place if no polarizing filter or circular polar- izing filter is used.

•If strong light is entering the PL filter win- dow, either attach the PL filter window cap or reverse the position of the PL filter win- dow (to top or bottom of lens). Strong light entering the PL filter window will defeat the effect of the lens hood and prevent the tak- ing of clear, sharp images.

•When the Pentax circular polarizing filter 58mm, which has the knurl ring on the back is used with the FA Zoom24-90mm f/3.5-4.5AL (IF) or FA Zoom 28-105mm f/3.2-4.5AL (IF) lens, the special lens hood cannot be attached. When a non-Pentax circular polarizing filter is attached, it also may not be attached.
