The new Sigma 17-70mm are just about the same diameter as the Canon 100mm macro lenses (new and old) so you might want to try using this gear for the Sigma, I know you can use the same gear for both Canon 100 and Sigma 17-70mm HSM with our housing, not sure if it will work with the Sea & Sea, but worth investigating, good luck.

Thank you!

Can someone please post the right S&s gear for the sigma 17-70 HSM?? #56350 doesn't fit, it's for the old version of the lens.

Did you get an answer to your question?   I am looking into getting sigma 17-70 HSM, S&S housing also.  Can't seem to find the answer on the forum.

What focus gear?  Anyone know for a Sea & Sea Housing (MDX-D300) for the Sigman 17-70 HSM lense?  I'll call around, but, if anyone knows that would be great.
Also, looking at the 60mm, however, I believe I would need a different macro port than the one I have.

I just spent 30 days diving in Palau with my D300 and my 60mm didn't leave the camera until the final week when I stuck my Tokina 10-17 on.
60mm is a great shark/dog tooth/barracuda type lens and when you come across a leaf scorpionfish/octopus/Nudi you are well armed to shoot them aswell.
I have the 17-70 also but frankly I would much prefer the 60mm for everything as its so much sharper.
Obviously if the dive shop can let you know when a trip to German channel and the mantas is scheduled you can set up for that but 17mm on the sigma lens is not wide enough in my experience for mantas and the 10-17 is much better suited.

I hope you don't mind my barrage of questions.  I need to make a decision over the weekend, if I'm going to buy something new.
A 60mm huh?   Nikon lense?  What housing do you have? Do you use a flat port or dome port with it?  Is a diopter needed?  (I get easily confused by diopter usage, just haven't studied up on it yet.)  I love SHARP and critique my pics intensively, so, this is something else to consider.  Definitely, wide-angle, will use my 10-17.

Yes, that's what happened on our trip. A friend of ours who is a photo fanatic took off after it.  He's fast and he caught it and got lots of great pics (of which, I would not look at).  The rest of us missed the opportunity.  OMG $1M a day.  Wow!
