depending on your MB you can rotate the filter stages to control the edge of hard edge filters. You want to get just the normal glass 4x4 filtes. I forget the exact thickness.
on my mattebox, which is an Arri, I have 2 4x4 filter stages, one of which is geared so i can put a whip in and move a filter up and down as i tilt, as well as a 138mm screw stage at the back of the MB which also rotates independantly. Then this all goes to a 90mm, i think, doughnut to cover the front of the lenses to prevent light leaks.
Your mattebox will vary; but you'd want to get one where you can rotate the filter stages.
it may seem like a huge expense, the mattebox, and the filters, but what it pretty fantastic is that if you go with a 15mm liteweight system, you can then adapt it to any rods system (15mm studio or 19mm studio) and the 4x4 filter and mattebox will work on pretty much any camera.
I've used my arri MB on everything from 435s, to Epics, to 5Ds, all the way down to some crab HV20s. it's sometimes a bit of an adaptation to get it to work on there, but never too much trouble.
I personally do not recommend resin filters for film work. They are prone to scratches and jut don't last ery long. a Good glass filter will last you many many many years.
I also highly recommend everyone pick up a white-water clear filter. it's just clear glass, but when you start putting expensive filters and lenses in dangerous situations it's important to have some kind of shield. Also you can do a lot of tricks with a clear filter and some household items to get interesting looks.
I would keep all the filters you may have which screw on for when you need to go lite. Some times for this will be on steadycam, or in tight situations. Sadly I don't have any screw on filters for my cine lenses as they don't have screw mounts, that I know of, so there are situations where i'd love to have a cheapo screw on which I can not worry about (imagine trying to throw sound, actors, camera, and director into a civic and you'll see how sometimes smaller is much better).
The Lee filters, btw, I don't think are made for film mbs, they were designed for some kind of holder system on stills cameras. i've never used them or seen them on a cine set.
Also, it's very important not to cheap out on filters. I tried that once with some off-brands. I was very very very sorry and very quickly out of a job when the client saw the dailies (film shoot), because they just suck. With a lot of film stuff, you really get what you pay for (and with some of it it's way overpriced and stupid to get..)
