I was hoping someone might be able to help. I have recently started to use the sigma 15mm with 8 inch dome and the advised port body for an ikelite system. All  seems fine with good performance throughout the frame.


I was thinking of using my Kenko 1.4 tc with this set up for greater flexibility, I wanted to ask someone who might be able to help from a technical perspective. Is there a way to calculate any changes in the system I might need to accommodate the the TC to ensure best performance? Maybe some type of port extension ?


Ikelite aren't great with this type of question from experience and hoping some clever person might be able to give some guidance.


Many thanks
