I think that all of these, except the Sigma 12-24 will work well behind the 8" dome port with the short extension ring sold by Ikelite. The exact extension length will need to be discovered through pool testing.

I have used the combo with the Canon 10-22mm lens, but at the time, the Tokina, Sigma, and Tamron alternatives were not available.

Any idea (or even better, data) how this lens and the Nikon 12-24 works behind the regular Ike's dome port?

I believe Peter S. has a review or info on his website.

Cheers

Besides the Sigma 12-24 (which does not fit in the port), I have dont think anyone has tryed any of thouse lenses in Ike housing. Mainly because the Tonkina is the only one that is on the shelves yet.

But as James said, it is expected that all but the Sigma 12-24 would work.

Anyone already know which port to use with the Tokina, besides the 8"?

First check out the specs of the lens.

According to b&h the lens is 3.3 inches long.

Then look at ike's page to see that for WA lenses between 3 and 4 inches you use port #5503.50.

We should be able to do the 12-24mm Sigma when new dome mold is complete in June as promised, late July as maybe, or whenever it shows up probably............
