Nauticam's port chart is extremely limited on the use of the 140mm dome for Sony n100 a7s/r full frame series.

Has anyone had any experience with native Sony lenses using the 140mm dome that they can provide first-hand commentary on.

No speculation please, just actual experience.

TIA

It's not a native Sony lens but the Laowa 10mm dome was tested and discussed extensively including using it in a 140mm dome some time back, here's a thread mainly testing Canon lenses and some of them including the 10mm laowa in the 140mm dome.

This was tested as Canon mount MF lens but they make it in a Sony mount in AF. In the absence of any experience on Sony native rectilinear in the 140mm dome this may give some idea on what you might expect, in general terms 140mm is regarded as too small a dome for most rectilinear lenses and I don't recall seeing much discussion on the topic here.

Some more detail on the 10mm laowa here, quite an extensive thread:

Scrolling down is some information on Sony lenses that work well in the 180mm dome.

The Laowa seems to be a special case working as well as it dies in the 140mm dome, it is generally thought that the very short minimum focus distance helps the lens perform better than other rectilinear lenses. Without doubt the best performer in a 140mm dome is going to be the Canon 8-15. Fisheyes play better with dome ports and can work very well in quite small ports.
