Kind of. What I really want to do is have a simple piece of material that I can slide into the cokin system slots, with a hole cut out of it with threads to fit a screw-in filter. There's a couple of DIY approaches that I can see, which have varying degrees of possible success and/or kludgyness: 1) get a real cheap ND8 P series filter off of ebay, cut out a 52mm hole, and glue in a 52->49mm stepdown; or 2) get a real cheap cokin-style round polarizer made for the backmost slot, take out the lens, and substitute a stepdown ring. Unfortunately for the latter, this will only go into the polarizer slot of the P series adapter, and will, by definition, rotate. Some ideas, anyway. One possible pitfall (among several) is the distance from the front of the lens. If I can mount this filter in the closest slot in the adapter, it shouldn't be too much different than the round filters that are made for the system.
