I use the Nauticam ports specific for each lens.
The port of the 14-42mm lens is the flat port 35, very short and it is possible to attach the Inon UWL-H100 without any vignetting .
With this combo I find the pictures quite enough sharp....
I don't see particular blurring or vignetting in the corner of the pictures made with the dome for the 9-18mm.....
But I am not so technical like you
