Can the front element rotate? Yes, the best polarizer I know of for the 20-35mm f/2.8 Nikon zoom is the one I use: B+W Slim MULTICOATED Circular Polarizer, and the front element does definitely rotate (it's a two-part filter like most polarizers, where the inside ring is threaded and screws into the lens, and the outside ring rotates the captive polarizer glass). Be warned, though, that this polarizer has no outside threads. The consequence is that you can't stack filters over the polarizer, and you have to get creative with the lens cap if you want to keep the polarizer on when storing your lens -- I've heard stories of caps from Pringle's cans... B+H in New York sells them for around $180, if I remember right. They also have B+W Slim MULTICOATED Skylight/Haze filters for around $130. As far as I know, using the hood that is made for the lens is always your best bet. It's bayonet-mounted, so the distance to the lens is always accurate, and vignetting (from the hood) should not be a problem. --Kristen
