If the Olympus 7-14mm F/2.8 PRO lens has the same excellent quality as the 12-40mm pro I think you will see a bunch of E-M1 users wanting one.

Reef has been doing retro fits of the Nauticam vacuum system in the E-M5 housings and it is a tight fit but works quite well. I have not seen the Backscatter vacuum system so would not want to comment on how well suited it may be for the EM5 housing. You can find my review of the Nauticam vacuum system in a back issue of uwpmag.com

That was no to the 12-40 working in the Nauticam 4.33" dome port for shotawong.

For Ted, yes the 60mm would work but you will need to get even closer to the subject and part of the focus area would be inside the dome. So good for the same larger subjects you would be shooting at the 40mm end of the 12-40 zoom and not good at all for the super close subjects like the 1:1 subjects.

No, it will not work for several reasons.

I have attached the Nauticam gear and acrylic port offerings. The gear is of excellent quality and fits like a glove. The Zen port also works with the Panasonic 7-14, 12-35 the 12-50 and more. 

 

As Barbara is finding out the 12-40 blows the 12-50 out of the water in regard to speed, (F/2.8) and overall  image quality and it will focus closer at 40mm than the 12-50 will at 50mm. Nauticam flat ports  would not work with the 12-40 because the Nauticam flat ports are to narrow to fit the bigger (more girth) lens.
