If you do happen to get interested and you're not using already a CPL, a screw-in ND would be relatively painless for tripod based work. Anything 4 to 6 stops (1.2 - 1.8 ND) is a good range for daylight/dusk (more stops for daylight, less for dusk) without having to run into Bulb mode (too often). Aperture and ISO will give a little wiggle room to push or pull things away from the 30sec timed exposure. If you're lenses have similar filter thread sizes, you can always swap a filter between lenses or buy for the largest thread diameter and use step-down rings to mount it onto the other lenses. Screw-on filters are also easier to get light sealed - though don't fall into the trap of leaving the viewfinder uncovered - you will get uneven exposure or patches of coloured flare!

If they are actually 2, 4 and 8 stop ND's, the 8-stop would probably need a gasket to seal against the holder and not let light leaks into the camera too.

Just tried the one marked ND8 and the meter reading only changed 3 stops, which would explain why when I tried to get a several second exposure on a sunny day I seem to remember resorting to as many as three of the filters in the end.
