Doesn't that just tick you off? I have bunches of system-wide filters from film gear, almost none of which fit any of my digital stuff (except 67mm). That's a lot of money! I also note that the makers seem to be making less of an effort to have just one or two filter sizes fit most of their lenses. e.g., My Oly digital slr lenses so far take 52, 58, 67 and 72mm.

The now nearly universal requirement for circular polarizers on newer cameras is brutal too. Coated CP filters are at least four times the cost of linears.

Oh well, photography is a better way of ridding oneself of extra cash than Indian casinos, and requires less driving. :-)
