Port, extension and gears for 17-35?

I looked on the subal site and am a little unclear on whether the zoom of this lens can be used in a housing. I have the SWB port and the 40 mm port extension but no gears are listed, should I take this to mean that it can only be used at a fixed focal length?

Subal lens and port reference for 17-35.

Hi Julie, I am sure it can be used as a zoom. Alex has one and can give you feedback on it. I just checked Subal's site and they do list zoom gears for it, but only in the German version:

Yeah, I have been using one UW since 2000. It is an awesome lens. There is a zoom gear that fits it - line it up so you can use the focus/zoom control on the left side of the housing to zoom it.

I'm not a Subal dealer or anything. So I have no idea apart the part number!

I also use the 17-35 on a Subal housing with the larger (I think that's the FE) dome, and a 50 mm extension ring. The zoom gear works perfectly too. It's a magical lens. I prefer it to the 12-24 mm for shooting subjects like sharks that cannot be approached closely enough for the 12-24 or 10.5 lenses.
