Wondering if there are any digital cameras (Point & Shoot) that are suitable for use on construction sites.
Any would unless you drop them, which is what I'm assuming you're asking about.
If you're concerned about dust, I think there are a few with fixed focal length lenses, which means less moving parts to attract dust. Or maybe something water resistant so they might be sealed against the elements.
Other than what I suggested, you'll have to be more precise in what you're asking for.
