I'm going on vacation to an area that has quite a few waterfalls and want to capture their beauty. I know I need my tripod and a neutral density filter. The only ND filters I have are the 52-55mm ND4, and a 52mm 0.6 ND filter. Will either of these work? The biggest question of all is which lens do I use? I have my Nikon kit 18-55mm, Nikon 50mm f/1.8 and Nikon 55-200mm. What do you recommend? Should I get a different ND filter? Thanks in advance!
