I would like to purchase some filters for my lenses, starting with my Canon EF 70-200mm f/2.8L USM Telephoto Zoom Lens for which I would want a polarizing filter. I know they vary greatly in price; is there a decent one in the $50 range? Also, can someone explain how the step-up and step-down rings work? Is that the way to go when a person has a variety of mm sizes? Any help with the filter question would be great.
I did some reasearch and then got a couple of Marumi polarizers. Taking MT's advice, I got the step-up rings so I can use the same polarizer on different lenses. So why did I buy two? So I can use two cameras on one shoot - one tele and one W/A.
