Considering buying these filters.
LEE Filters Graduated Neutral Density Soft Filter Set 4 x 6" - Consists of Three Graduated ND (Neutral Density) Filters (.3, .6, .9) - Soft Transition
These will be my first ND filters. Any issues with these filters that I should be worried about? I also need to get the foundation kit to hold the filters on the lens. I'll be using a 18-140, 1:3.5 VR Nikon lens, 67mm.
thanks!
