Lenses with simplified weather-resistant construction: These lenses are made with a simplified weather-resistant construction by using DA* sealing technology which makes it difficult for water to enter the lens.

Immersing them underwater is not OK, you need a waterproof model for that, such as the W90.
I haven't looked into the industry rating system for cameras, but there is one and cameras are given a rating dependent upon their degree of waterproofness.
