Pentax SMC -FA Camera Lens User Manual


 
Filters
Select the filter matching the lens
filter size, then screw it onto the front
of the lens.
* The FA
600mm f/4ED (IF) lens
has a filter holder in the rear to
hold the 43mm filter provided with
the lens. For details, see the FA
lens instruction manual.
Filter Cautions
When attached to the lens, the fil-
ter becomes part of the lens optics.
Therefore, handle it in the same way
as the lens. Keep it clean from dust,
scratches, smudges, etc. Except for a
circular polarizing filter, avoid attach-
ing more than one filter to the lens.
Using multiple filters is not effective.
