Digital Filter Pro

I need to buy a Polarizing Filter for my canon 40D EF-S 17-85mm lens. what is linear and circular?

I found HOYA PRO-1 Digital Series Polarising Filter (Circular) on Amazon.co.uk. is it a good filter? is it work with my camera? where can i get cheap? i want to use it ot outdoor photography. Many thankx

Hoya Pro 1 is an excellent polarizing filter. I also shoot a Canon 40D and just bought a polarizing filter. However, I bought a Tiffen only because that’s what my Professor suggested. Both Tiffen and Hoya are excellent brands. B+W is also i great manufacturer too. Although they’re little more expensive. The only reason for the higher cost is B+W filters are stack able. They are made with a higher quality metal so they won’t fuse together in your camera bag. You can purchase the safest cheapest site is off of B&H video.com. This where i buy all of my camera gear and accessorizes.
