It depends on the diameter of the lens (should be printed on the lens). But as long as the diameter is correct it will work. These are "circular polarizers" as opposed to "linear" ones and are designed to work with AF cameras.

Also bear in mind that this filter will reduce your effective f-stop and thus certain cameras with already high f-stop lenses will have issues with AF working properly.

Yes, that's right. They are primarily designed for wide angle lenses to prevent vignetting. However you can screw the CP onto an existing standard filter.
