Hi thanks for info, i have skylights as protection on the lenses. So a question? 
Do I put all the filters on at the same time, i.e taking a shot of a sunset on water would I leave the skylight on and put the polariser on to reduce glare of the water? What effect does this have on the light gatthering element of the camera? 
 
I have some extra cash which I thought i would use on buying some filters. I'm not interested in the gimmicky ones i.e star filters etc.
