Yup, and later got the Promaster branded version in AF for EOS. The
largest c-pol I have is 55mm and the largest linear is 67mm, so I've
never tried one on the 19-35.
I'm not sure I've used a polarizer since I went digital with a film
scanner. I'm not a big one for carrying a lot of bits and pieces and
most of what I used to use a polarizer for can be done other ways now,
and without the loss of speed:
1. Darkening sky. On a super wide, this doesn't usually work out very
well, as the angle of polarization of sky light varies with angle, so
the effect varies across the frame. On the other hand, it's easy to get
the desired effect in an image editor.
2. Controlling bright reflections. Often works well for this. Post
processing is more work, but usually does the job and will handle all
reflections, not just those with the right angle/polarization.
3. Suppressing reflections on water to photograph what's down in it or
glass to shoot what's behind it. Here, there is no substitute for a
polarizer except finding an angle where the reflections aren't a
problem. An editor is no help. Of course, you can just try to work with
the reflections. I think this shot would be less interesting with a
polarizer <http://galleries.moosemystic.net/GGPark/Flowers/pages/FL36.htm>.
