Many photographers are divided on the use of protective filter, some feel that it is not necessary or taking the filter off for some types of photography shooting.
Is it true that for digital photography a clear protective filter is all that is needed as the sensor does not have the sensitivity of film to UV and blue light. UV and Skylight filters are used for cameras with film ??
Did anyone actually test (non-scientific) using different filters (perhaps different brands/types) and did see some differences for outdoor shots.
Is B+W really worth the money even for a 17-55mm/2.8 len (I know it is just a fraction of the cost of the len) but I am really curious to hear if there is really any noticeable differences for general photography ?
