canon 11-24mm f4l usm

I ve been looking at the new canon ef 11-24mm f4l usm lens has anyone tried it yet ,I can't seem to find a zoom gear for a subal housing or any other housing manufacturer

Sea&Sea produce a specifical kit (dome 240+extension ring+ zoom gear) to fit the 11-24 in MDX Canon Housing.

I'm a nikon user, I'm waiting to try the newest Sigma 12-24/4 ART in my MDX-D800, in case it will be possible.

I just posted something similar here on EF11-24.
