I'm am so confused. :? I've started looking for a circular polarizer and have seem them as cheap as $30 up to $100+. Can someone please tell me what I need to look for in one? I've heard that Hoya, Cokin, and Tiffen are all good brands, but even these guys sell multiple price levels, slim, ultra slim, super mutlicoated, etc. I have a Nikon D70 with a 18-70mm lens. I don't need the best on the market, but I don't want one that will negatively impact my pictures either ....

Thanks in advance for your help.

Michael

Here's Hoya's explanation of their technology:

Thanks, Mike.

I hope you run workshops in your community. You have been such a valuable resource for me in my photographic education.

Yes, thanks very much for the link! It's very informative. I'd been leaning towards hoya anyway, so it looks like I might get the mulitcoated. I'm sorta thinking about the thin one to limit vignetting because my lens does do that sometimes. It's widest angle is 18mm though. Any thoughts.

thanks

Michael

The only exceptions are Polarizer and Circular Polarizer filters. No matter the brand or quality, they all are made of a polarizing film, or a polarizing film and quarter wave plate in the case of the Circular Polarizer, sandwiched between two layers of glass.


Straight from that page.....Is that true?

That page is down right now so I can't see the entire context...but if you're asking if that's the basic makup of a polarizer, yes...and a circular polarizer is only a linear polarizer with an added 1/4 wave plate which is for cameras like dSLRs which have a semi-silvered mirror or beamsplitter to split the light between the imager and optical viewfinder.
