Sorry, I forgot this bit Poo.
No, polarisers are filters that screw onto the front of your lens. There are basically two types..........linear, and circular. Circular doesn't refer to the shape but to the fact that it won't interfere with your camera's metering system, so for cameras with through the lens metering............which is most, you need a circular. There are also filters and filters...........the higher the price, generally the better the coating on the filter. If you decide to buy one I will clue you up on the best for your camera.
Back to you thinking about DSLR........I've researched a lot and I think I've got the best prices to be had, if you go down that track.

panasonic lumix............retail outlets in brizzy were asking 200 bucks more than I got it off ebay from an Asian dealer in Perth via ebay...........it came with an international warranty and a free polariser and UV.worth over 100 bucks.........any wonder Aussie business ain't competing?
