Have a look at camera shops for bargains on filters. I picked up 5 for $10 at one of our big dealers. Apparently DSLR's just don't use or need them with AWB fixing the pix. I found a blue 80A that fitted my 300mm and when I fitted it to the lens it went blue for about a second then corrected !! Take it off and same process in reverse. So Filter sales are down in the dumps.
But !!
What I did pick up was a pair of polarising filters with rotating eements. Fit the two together and voila you have a variable ND filter all for $4.
The 80A will hopefully counteract some LP for widefeild instead of a LP filter. Just playing with ideas.
