    On which of your lenses do you like using your polarizing filters and why ?

    Its not so much what lens but what setting...when shooting outside I generally always have one on. When shooting inside it needs to come off.

    Actually my CPOL fits all my lenses. As I bought the best (what I felt was the best) CPOL that fit my largest filter size. And then bought adapters to fit it to my smaller lenses.

    As for use, like above on most of the time outside in daylight when shooting scenics. Off at night and inside.

    How does that effect your aperture? I can't see how using the same filter on a 58mm f/4 lens would work just as well on a 72mm f/2.8 lens.
    Not saying it wont, just need education on it I guess.

    Well if he has a 58mm f/4 lens and a 72mm f2.8(assume this is the largest he has), then all of his filters are 72mm in size and he has step down rings for the 58mm lens. This wouldn't affect aperture or anything else since the filter would be bigger than the front of the lens.

    Duh! I can be such an idiot sometimes...somehow I missed the largest adapted down to smallest part of that.

    One thing that bears mentioning -- don't use a polarizer on an even moderately wide-angle lens, if you're going to use it to darken the sky. The sky will polarize unevenly, and results in a weird coloring issue where half of the sky will be darker than the other half -- depending on positioning, of course.

    This is not a "Don't use" but rather a creative decision. I'd take a half dark sky over a flat image anyday if the polariser achieves other purposes like removing glare on a lake. There's no rule to say a sky needs to be evenly dark.

    This is also very true, but depeding on composition it can make for a very awkward picture. It lends itself to more of a surreal photograph than one of what you actually saw through the lense. You'd prolly be better off using a 2 or 3 stop filter to darken up the sky rather than just use a polarizer. I guess just depending on what look/technique you're looking to achieve.
