I'm a relatively new EX-3 user. Loving the camera so far. It has a few quirks but is capturing some truly stunning stuff. This is my first purchase in the HD realm. Until now when an HD project would come up I would rent. In those situations I often rented a matte box which came with a pretty expansive filter kit.
Now that I own the camera I bought a matte box that can take 1 4x4 and one 4x5 filter. Since I can't afford a huge selection of filters I thought I would ask everyone, which filters are in your must have kit. I'm thinking polarizer, and solid and grad ND filters at .3 and .6 (haven't had use for an .9 as yet). Anything else? Anyone know where there are affordable kits that will allow me to not have to spend $300 and up per filter?
