That's actually not true as my hiking boots and science will prove, air molecules are smaller than those of water and there for you can say that if water can go in and out, so can air.. but not vise-versa.
but drec, the technology of WR lenses lies not only on the outer "holsterings" or gaskets.. internal layers and seals between elements are a key issue for the WR badge the lens get when appropriate..
I think you're better off, saving up for a sealed lens like the DA* lenses and in the meantime be sure to treat the lenses with common care and try to wipe off water and such when shooting in rayn or drizzle..
I've never had a problem with the K10d and the kit lens, even when I once nailed it trough a bank of snow high in the mountains here in Iceland.. it was fine..
