Subal recommends the DP-100 dome port for both the 8mm and 7-14mm panasonic on their website so thats why I´m wondering if anyone has any experience with them. Thought it might be a god alternative to the zen glass ports when used with the Nauticam to Subal port adapter and then one could use the larger sizes for Over/unders as well.
I intend to use them with the Nauticam housing for Olympus E-M1.
Also looking for a larger port (larger than Nauticams 3.5 and 4.33) for the 8mm panasonic for over/unders and thought maybe the larger subal alternatives could be good options?
What is the weight of the zen ports you use? I have not found any mention of the weights anywhere...
Any reason you chose the Zen 100mm port instead of the Subal DP-100 port? Are they comparable?
