The clue is in the title, "resistant" and not "waterproof".
My diving watch for example is not claimed to be waterproof, but water resistant to 200m.

A remarkably good lens for the money.
After that you are into Sigma/Tamron/Tokina territory.

It is a layout for making long lenses small and light. On the downside, there is usually a price to pay in terms of image quality, they tend to be fixed aperture ( usually F8 ) and some of them produce a weird doughnut bouqeh.

It's defined on page 7 of the lens instruction booklet, up to a point. In practical terms it is a useful feature though that offers better water resistance than standard lens manufacture.
