Hi,

Hi JS,
Have you had an opportunity to review the links I provided? Do you have any other questions?
Since you had mentioned that Alex Mustard had some problems with the Sigma 15 and his Subal D700, I re-read his “Thoughts on Mini Domes”. The backing plate of the UnderWater Camera Stuff Modular 5” Dome for the Sigma 15mm has been designed to eliminate the problems he described. When compared to the backing plate of the Tokina 10-17 Modular 5” Dome, you can see that the Sigma 15mm backing plate has been (using Alex’s words) “machined away to work”. The picture I posted in an earlier reply shows the difference in the backing plates.
As I said earlier, I do have a blemished dome that I could loan you for evaluation. However, with a shipping costs of $40 in each direction, it seems cost-prohibitive and not a good option. We will be starting a new production run of the Sigma 15mm domes soon and I could hold one for you from the batch. I am confident the dome will perform well with your system but, if you discover any issues once you use the dome, I will work with you to reach an acceptable resolution.
Please let me know if I can be of further assistance.
Bill
