unless you got very very thin filters, you'll have a LOT of vignette if you stack filters, especially for wide lenses.

I was gonna say exactly the same thing.

At 28mm, I can't stack my CPL on top of my UV filter without getting a bit of vignetting. At 24mm, the vignetting is bad enough that the photo becomes unacceptable.

Also, not that it is a big deal, but in response to Sheep, how often do you need to reduce glare / reflections from windows or bodies of water? I think getting a deep blue sky has more merit (and usage frequency) than glare / reflection elimination wor?

You do when you're a landscape photographer.
Well, I am not a landscape photographer so I use my polarizer to get better colour & contrast during sunny days.

I actually never try that myself, but I know another guy use this method.  Maybe he is not shooting wide angles then.

It is handy to know if you ever need to shoot slow shutter under bright sun.

    I am just saying that the filter is design for such purpose. You can do with whatever filter to achieve whatever effect you want. Photography is creativity.
