Can you see if it's coated (anti-reflective)? May show as a tint on the glass.

Yes, it is.

Hi Atus,

Which mount did you get? I don't understand the Sea and Sea mounts (DX and NX) and which one suits Isotta.

Thanks

I got the NX mounting, I guess this dome is not made in the DX mounting. You can mount NX Sea&Sea mounting in B120 Isotta housings. But you can't mount Isotta on Sea&Sea hosings. And furthermore, you can use a lot of N120 Nauticam ports by changing its screwed lug in Isotta housings and Sea&Sea housings.

Hi Atus,

Could you test the Howshot 140mm dome? How does it perform?

I just wonder, since I am considering buying one.

Hi, I didn't have so much time for diving in the last weeks but I have test the dome and compare it with the Nauticam one which my dive buddy has. There's no difference at all in performance, in terms of construction is very solid and there are only two differences with the Nauticam one, the howshot shade can be removed by hand because you can release the screws with just the the hand, they have knobs. But if you prefer it they also send the prisoner allen screws to handle the shade. In the Nauticam dome the lug is machined in the dome body, in the Howshot one the lug is screwed, so yo can use with Sea&Sea, Nauticam and even Isotta by changing the lug. Here you can see two pictures with this dome, both with Canon R6 MkII, one with the Canon 8-15 fisheye lens at 8 with the extension ring which Isotta recommends in his port chart. The other one with the same camera, same lens and Kenko 1.4x converter, the picture is taken at 15 mm with no crop. As you can see the corners are not perfect but there is a huge difference comparing with the 4" dome port, and as I said I can't find any difference in terms of performance with the Nauticam one. I would buy it again.
