Pentax INTERCHANGEABLE LENS User Manual

Page 16

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.

Screw-in Type Filters
This type of filter screws into the front of the
lens. Make sure to use the proper size
Pentax filter specially designed for your lens.

Precaution on filters
Attaching the filter to your lens becomes a
part of the optic.
Avoid using no more than one filter exception
of with a polarizing filter, as deterioration in
image quality may results.
• Attach the 43mm filters supplied with fol-

lowing lenses to the filter holder in the rear
of lens.
FA 300mm f/2.8ED (IF)
FA 600mm f/4ED (IF)
FA 250-600mm f/5.6ED (IF)

• A filter cannot be attached to the F Fish-

Eye Zoom 17-28mm lens.
