7i and circular polarizer
I have a Dimage 7i and tried a circular polarizer on it. Neither the EVF or the LCD gave any indication of polarizing. I watched the EVF for any changes in exposure and saw no shift. Any tips? Should I just rotate the bezel and take shots hoping for polarization?

Try a reflective surface , you will see the effect : glass table top, water surface … , the light glare will be cut off and you will be able to “see through” the glass, the water surface …

Polarizing Filters
The amount of effect you get depends on the direction you are facing relative to the position of the sun. If the sun is directly to your right or left you will get the best polarizing action. If the sun is in front or behind you, you will get no effect at all. If the sun is directly overhead, you probably won't get any effect.

If you are using the polarizer to darken the sky and emphasize clouds, sun position is very important. If you are trying to remove reflections from a window or other shiny surface, I'm not sure the sun position makes any difference.

Also, most circular polarizers will have a mark on them indicating
maximum polarization effect. can polarize accordingly.

Just to say that your light source doesn't have to be the sun...I've personally used a polarizer when shooting something on a reflective countertop at night and the light source was a fluorescent light. Here's a page with examples:
