No one has mentioned the polarising lens, that you specified. This correctly is a filter placed over the lens. Any camera lens having a screw thread for filters will accept a polarising filter. It is easier to use such a filter on a lens on which this filter screw does not rotate when the lens is focussed or zoomed. Many low cost kit zooms rotate whn zoomed or focussed. Check with your dealer before buying. Polarising filters come in two types(as well as many diameters). Circular polarisers work on all cameras. Linear polarisers are cheaper but prevent correct functioning of the AF and AE on most DSLRs.
