I want to be able to use ND filters for my SK35XL and SK 72L.
I use the centrefilter on the 35XL and that outer filtersize I believe is 72mm (I think). Now, can I use 72mm ND filter straight on that centrefilter with lensmovements or is it wise to go up further in size, say, a stepupring and 77mm filter?
The 35XL is a 52mm without the centrefilter. How about putting on a 52mm ND and then ontop the centrefilter? Bad idea?
Finally, does anyone now of stepuprings that goes all the way from 40.5mm (72L) up to large filtersizes like 72mm or 77mm?
