[Leica] help! stuck filter!

[leicar at q.com (Aram Langhans)]

Now that makes perfect sense.  I have the same Heliopan thin polarizer, but 
on a 35-70.  At times it is bound like it is welded to the lens.  I try and 
try and it does not budge.  Then, with a very slight effort it comes of 
easily.  It is so thin and so close to the lens my filter wrench does not 
even want to grab it.  And working from the front, it just rotates like any 
polarizer is suppose to.  So, I would just work at it slowly with mild 
pressure and maybe yours will behave like mine and come loose.  I know brass 
is not suppose to bind, so the distortion hypothesis makes perfect sense.  I 
just always forget and grip harder and twist harder until I remember that a 
gentle touch often (not always) works best.
