VizBiz 0 Posted January 23, 2013 Hi all, I have seen some nice result with the Tokina 10-17 + 1.4 TC on the D800. I have Ikelite kit with a D800 and 8" Ikelite Dome. What extension ring/s do I need to add to the dome to get spacing correct? Part numbers would be great so I can order ASAP. Thanks Share this post Link to post Share on other sites
blibecap 29 Posted January 23, 2013 You will need a new port that is 3/4" longer then the current port. That is the length of the 1.4 teleconverter. The part number you are looking for is a 5510.16. ikelite does not recomend a extension with the 5510.10 or 5510.11 Share this post Link to post Share on other sites
