        Blue Focus on these lenses is usually very poor.  As long as you use a it
for B&W work, witha yellow filter, it may work just fine.  For a good
source of filters for these lesnes, try out Surplus Shack at:

        Sometimes, depending ont he age of the lens, you may have to stop if down,
with a manual stop.   Still at say F4, it will be plenty fast enough to do
some work with.
