I was at my local camera shop and since there was a 25% off sale on Promaster filter lenses I thought it would be an opportune time to buy a polarizer for my Panasonic FZ7. They were out of linear type but did have circular polarizers for $29.00 before sale discount. Then I noticed they had "Digital Circular Polarizers" however the price before sale discount was $119.00 for these.:?

Are these "digital" polarizers worth the extra money, or will the circular or lineartype work just fine?

If the $30 filter is a lower grade filter and the $120 one is a good brand's top filter there would be a quality difference. But linear and circular are the only two kinds of polarizer I know of. The "digital" designation would just be one brand's designation and not an indicator of utility.

All the same brand. "Promaster". Sales person says Hoya makes them for Promaster. When I look at the Promaster web site the hoopla for the new Digital series seems pretty high compared to the past standard? Is it all just up-selling?

You will get no more polarizing effect with the digital version. What you will likely get is a higher quality lens and coating. If it is the same brand filter I would think there would be a quality difference.

There is no such thing as a "digital polarizer". It is a brand's name like Caprice or Raptor. There is no special quality you can add to a polarizer that makes it more appropriate for digital cameras.

Whether you want to pay more for the top of the line is up to you. I would go with the thirty buck version and return it if I could see quality defects in normal use.
