Hang on a minute, why did pros of old use series filters then, other than
the fact that they were for particular lenses which were highly regarded
having that thread rate, and may have been of higher quality?  If it was
because the filter glass was of higher quality than contemporary non-series
mount,  then for us today the more easily obtainable non-series mount
filters with modern coatings and glass will be superior and cheaper.

The only possible advantage that I can see for retaining the Hexanon Series
filter adapter is that it adds strength to the rim of the lens - if you
always use a UV filter then this will probably do the same thing.

I don't really like filters and have several lenses without - the only
filters that can be essential are the UV and the polariser.  For the
Rapid-omega it is probably easier to use a Cokin or similar sqaure filter
given the hassle in trying to work out relative rotations of a glass
screw-in polariser.  Anyone have experiences that they would like to share?
