In using my 35 Summilux ASPH (2nd generation) for night 
time photography in downtown Portland, I have found 
that the use of a filter (UV haze, B+W brand) *appears* 
to accentuate both reflections and haloing of 
streeghtlights.

I keep a filter on as I cannot quite deal with the notion
of smashing in the front element of a nearly $2000 lens.

I've started removing the filter in these situations,
and I've always removed it when the camera's on a tripod.

However, I have yet to do a formal test of a single
scene with/without, at a set of different apertures. 
You've given me reason to do so now (I'd been thinking
of doing so anyway, because I'd like a more detailed idea
of exactly what the filter does), and I'll get to it 
in the next week or 2. I will post my results to the LUG.
