It's cool: as described above, sometimes I don't mind having a couple of different hoods, particularly for odd lenses, (like the one pictured above: it goes wide-to-tele, has a pretty hard-to-find stock hood, and vignettes easily, so the little metal hood and one filter are the usual arrangement, but it doesn't actually cover much, so the big rubber one goes on when circumstances require or allow. )
I expect it might be a similar circumstance when I get hold of a zoom for my digital, but I haven't actually chosen one yet. Good to have options like that, though. I fuss with enough step rings as it is.
