Hi all, i would like to find out more about the compatibilty of filters on my UWA lens. i have seen many reviews that recommend both such filters (ND and CPL), but which one is more suitable for landscape photography? For ND filters, will a square filter kit affect the vignetting when it is at its widest? For CPL filters which one is more durable and better in quality, Hoya or B+W becos im eyeing these two.... please give some advice and hopefully i can make my decision cheers!
