Finally got the Lee Foundation Kit along with a couple Hitech GND filters (my early birthday gift from my lady!). I love it! It makes the position of the GND much more flexible (up, down, diagonal, etc.), and doesn't have any vignetting when zoom all the way in! I could finally use my UWA lens @ 12mm instead of 14+mm!! Now I just need a couple more higher density ND filters (6+ stops, Lee's Big Stopper, etc.) and I'll be a very happy photographer!
This shot was using a Hitech GND 0.9 set diagonal along the edge of the row of boats.
