OP
Thanks for all the advice.
So what we've wound up with is a Titan D200 housing, a pair of Inon Z-240s, assorted
Ultralight arms, a Hartenberger Nano focus light and the following lenses:
Tokina 10-17 fisheye
Sigma 12-24 wide angle
Sigma 17-35 wide angle
Nikkor 60mm micro
Nikkor 105mm VR macro
The Titan has ports/gears for the Tokina 10-17, Nikkor 60mm and 105mm VR.
The Sigma 12-24 isn't going to work in that housing. Light & Motion also doesn't
support the Sigma 17-35, though the dimensions on it suggest that it might
work since they do support the Nikkor 17-35.
The Nikkor 17-35 is 82.5mm in diameter; the Sigma 17-35 is 83.5mm. There's
some chance that the Titan gear will work.
The Nikkor is 106mm in length, and the Sigma is quite a bit shorter at 88.7mm.
So chances are that I'd need a different extension ring than the one Light & Motion
recommends for the Nikkor.
My next question for the group is can anyone give me some guidance on which
extension ring from Light & Motion might work? (I've asked them directly and
they have said "we don't know").
I'm not entirely sure that the Sigma 12-24 lens would be useful under water, so
I'm less concerned about it for now.
