I am sure the old farts know this well, but perhaps it could be
helpful for somebody else...
I just got a severely stuck filter on my 80-200/2.8 zoom, from screwing
hard a huge long metal lenshood onto it.
Now just gripping the filter would bend it even more, worsening the
problem.
Just grip the lens barrel in rubber glove (for good friction) and put
the lens filter down on a sheet of rubber on flat surface (another
rubber glove could do in a pinch). Press hard down and turn. Voila!
Good light!
