As from bright light sources in front of the lens...? ;-)

Ah, Tiffen..... You may want to check the Tiffen filter for

fog - these tend to "self-fog" in a relatively short time

(mysterious - no other filters I've used but Tiffen do this)

and require cleaning before use every few weeks or they

diffuse the image. A clean, good filter will normally, under

most conditions, have no ill effect on the image when

used in front of a lens, "contrary to popular opinion"...;-)
