stever 0 Posted November 18, 2008 The EF-S 60 macro focus gear works for the Tokina 11-16 2.8 on my 20D in Aquatica housing. They may have changed the design of the gear, but it should still work. Do i need a diopter with the 8 inch dome port? Have 10-22 with zoom gear for good price. Share this post Link to post Share on other sites
Undertow 31 Posted November 19, 2008 I use the gear for the nikon 12-24mm and it works fine. I would suggest a diopter, really helps corners at wider apertures. I use the 9.25" megadome though. Cheers, Chris Share this post Link to post Share on other sites

Scooby00 0 Posted November 20, 2008 With my D300 housing and the 8" dome port I use the 18463 extension ring http://www.aquatica.ca/subpages/catalog/product/rings.asp Simon Share this post Link to post Share on other sites
Undertow 31 Posted November 21, 2008 i'm using the 18456 because i already own it for the nikon 12-24mm, but i think the 18463 would be better. Share this post Link to post Share on other sites
stever 0 Posted November 24, 2008 with the Canon, the 18453 works, but the 18462 might be a bit better (or not, and i'm not packing another extension) i've also heard the +2 is a good idea with the 8 in port, so i'll add that Share this post Link to post Share on other sites
