I have found that the S&S ring that fits the Tokina 10-17 fits but I needed to add a 1/2" rubber band to the barrel to make it nice and snug. The S&S gear says it is for a "Cannon EF 16-35mm F2.8L USM Zoom Gear". Also have a F.I.T. gear for the "Tokina 10-17mm" that is same I.D. but not quit as long. Between the two I prefer S&S on the 17-70. Think it would work for you.

Hi John

I have the Sea&Sea housing for the D80 and it is / works super.

It is compact and for me it has a nice balance in the water. There are a lot of ports for the housing and they can be combined to fit many lenses.

Thanks markprior and scubanimal for the answers.

Now I have to test and try, to get this “thing� work in the housing.
I have the compact dome port, SX and 40mm extensions, so I have the basic tools for the test.
