Great tip - thanks! I was uncertain about the Z-Pro system for that reason, but one filter is usually going to be sufficient so if reversing it will get me a little wider than 20mm, great. Plus, it would give me a way to mount a Lee Big Stopper on a TS-E 24mm II, since I can't seem to find any round/threaded 10-ish stop ND filters in 82mm.
