Hi Shel,
A simple filter flare test can be performed using a lamp fitted with a small
quartz halide globe and and most any SLR/lens and filters under test.
Filter in hand place it in front of and close to the lens (sans filter), point
the camera at the lamp whilst looking through the finder such that the lamp
creates flare in the finder, note the degree of flare or even commit the
offending article to film, swap filters and test again.
Cheers,
