A recent thread brought attention to a concern regarding potential harm to the f ront element of certain Nikon and Schneider lenses caused by a screw-in filters.

I called the Nikon US tech support line (800-NIKONUS)and asked their opinion. T hey claimed to have NO knowledge of a problem with any of their lenses, or of an y warning given with the lenses. I wonder, what gives?

By the way, series filters give a good bit more clearance, but are less convenie nt than regular screw-ins, unless an adapter is dedicated to each filter.
