I've got a quick question for any experienced photographers out there about polarizing filters. I've read and heard a little bit about the value of polarizing filters. I went to Ritz a week ago looking for a polarizing filter and wanted a cheap $20 - $25 one I had seen in their online catalog. The guy tried to sell me a $60 polarizing filter and said this is what they recommend for digital cameras. He said the cheap ones are for film cameras. He said the cheaper one might work but the other one was better.
My question - is this true or was he just tying to upsell me?
I got to borrow a friend's camera this weekend and she has the Nikon 18-200mm VR lens on it and it was everything it was advertised to be. I took two shots of the same subject at 200mm using the same aperture and shutter speed settings, one with the image stabilization off and one with it on. It made a huge difference. So guess what? That's right campers, mister "I gotta have it" here wants to start saving for that lens.
Which means I want to go the cheap route right now if I buy a polarizing filter. I'd like to get a polarizing filter before the fall leaves reach their peak, but I'm also content to get a cheap one that is just "good enough for now." So, is the $20 polarizing filter an ok thing, or is it $20 down the drain?
Oh yeah, one more thing. Are there any technical details about the use of polarizing filters I need to be aware of since I am a total noob on this stuff? I've heard the polarizing filters will reduce glare and make the colors more vivid, so that's all I'm looking for - does anyone have any advice to offer?
