For who is interested the Leica 12-60mm fits into the 6" dome port however at around 54mm the lens touches the inside of the port so it needs an extension I had a 30 mini extension ring to try.
With the extension ring the Nauticam zoom gear does not go through however using a 3D printed gear I managed to make the whole set up work
So I now have a 30 mini extension ring with the 6" wide angle port working with my 12-60 leica quality is better with the extension than without dimensions looks the same as the 7" port in length now
In terms of optical quality is excellent even at f/2.8 I am not planning to get the 7" port but I would be betting that at 12mm the field of view is narrow enough that 1" mode diameter is not making a difference.
If anyone wants to know more I will do a write up when I have time
I am very excited to use this lens for video with a focal range of 24-120mm in 35mm equivalent going up to 168mm with the ex tele function this is going to be as near to a camcorder as you can get a micro four third
