Thank you. That's actually a good idea, and I can test it right away with my Canon G9 and the underwater housing that I really never used.

I also saw this one in doing more searching around:

which touts weather sealing. Wonder if it's enough for the fine dust I'm trying to avoid. I don't expect we'll be changing lenses often, and if we do, it would be in the showroom area, not in the dusty production area.

Reason on the matter for a moment: Which is larger, a dust particle or a molecule of water? Correct, so if a camera/lens can seal out water, then it has to be able to seal out larger dust particles.

But think (or drink or bath in) water in the usual sense, not as vapor or air humidity: it doesn't come in loosely scattered individual molecules.

So reason on the matter just another moment: which is larger, a speck of dust or a water droplet?
