Hi. I have a Canon 17-85mm zoom lens and I lost my Kenko Wideband polarising filter during a shoot on Saturday. I looked everywhere but no luck. It cost me $124. Anyway I need to replace it. I was just wondering what polarising filters are affordable but still great quality if possible (should I stick with Kenko). I've looked into Hoya, which I think are the same as Kenko. I can't believe my filter fell off without me realising. Argh.
