One of the cons of shooting with a DSLR or the FS100 is the lack of built-in ND filters. You'd like to use a matt box but some EF zoom lenses actually extend when you change focal length so matt boxes won't work. That leaves screw-on ND filters.
Using a complete set of ND filters can be a pain so some shooters opt for Variable ND filters. They are basically two polarizing filters set to rotate against each other. I'm not a polarizer fan because of the color shift. And I'm not sure they should be called ND filters because the N stands for Neutral and using polarizers will change the color.
Also, you can get a "X bar" across the image as you go darker, especially with a wide angle lens. There's a great video clip on this blog showing the X bar problem. Also, this is a 2 page blog so be sure to read both pages:
