AC90: Polarized filter for AC90

I use my AC90 mostly as a run and gun camera. I have noticed with my new polarized sunglasses how much deeper the blues in the sky are with them. I borrowed a polarized filter for my Canon XS, just to goof around. I didn't really notice that much of a dramatic difference. I may just not known what I was doing. So I turn to the forum when I want the right answer. If I get a polarized filter for the AC90, will I notice that much of a difference outside. Outside I use an ND filter, which is a must. I don't think I can stack them because when I zoom out I will catch the edge of the 2nd filter. I am always moving the camera, usually on my shoulder, and go from ground to sky and back in the same shot. Will the light hitting the polarized filter change when I do this? Also thanks a bunch to Panasonic for the upgrade AND great step by step instructions. Never did an upgrade before and was afraid I would do something wrong. Everything turned out great.

Get a Circular Polariser for zoom lenses.
It has an inner and outer, the outer ring has a mark and rotates.
A rule of thumb is to move the mark towards the sun.
CP filters change the look as the outer ring is rotated.
Yes, it will make a noticeable difference to the picture similar to your sunnies and drops exposure by around 2 stops.

Hi Jim,

yes a polarizer is a lovley filter to have. I use one a lot when i'm filming by the Devon coast, not only does it help pop the sky but i use it to remove some
of the glare off the sea. Also if your filming through windows, you can eliminate a lot of the glare off the glass if you position yourself correctly.

For the deepest blue sky's, the sun should ideally be off about 90 deg from where your lens is pointing, you then rotatate the outer part of the filter to get the look you reguire.

(note, if your panning around, the effect will change the closer you get to the sun)

Polarizers come in either linear or circular type, circular used to be used in SLR's as they had beam splitters for the metering/focussing of the camera. Ask around or do a bit of googling to see what works best for your cam. I would buy a decent brand though as i've heard some of the cheaper filters may introduce a bit of colour shift when rotated.

Also the Polarizer acts as an ND filter as well so you shouldnt need to stack an ND and Polarizer unless your somewhere really sunny (im in the UK so we dont get that problem here lol).
