Ikelite port length for Tokina 10-17 + Kenko TC 1.4

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

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
