Just heard that Amphibico have confirmed that they are making an underwater housing for the EX-3. It should be available around July time for around $12K for use with the standard lens however extensions etc to fit additional ports will come later.

Some pictures from another forum. If anyone is interested.

As another update for the EX-1 R, Gates housings for the EX-1 will not work with the Ex-1 R however they are designing another housing which will.

Do you have the Gates housing for the EX1? And if so how do you find it to work with?

I don't but I have used it, I have the Canon A1 with a Gates housing and I love them. They are extremely rugged, easy to maintain and the Fathom optics are really good. They aren't cheap but that's underwater equipment for you.
