Zen 100 port for Tokina ATX 10-17 causing soft images

29 January 2013 - 03:34 PM

We have a Nauticam D7000 housing and while shooting mostly macro we discovered the Zen 100 port caused all WA images to be slightly soft and lacking sharpness. It works with the Nauticam #20 extension ring but has vignetting on full wide but at least no focus issues. We have checked the lens which has a build in "port" designed to verify it is correct model and the Tokina lens works fine out of water-correctly but in combination the same issue. We had thought it was just us till Burt Jones was nice enough to trouble shoot this on our last trip.
Has anyone had similar issues or possible fix?
Thanks.
John
