Well, at first we were making that port and gear just for our own fun! Because tired of shooting the Sony 30mm Marco.
We have not been so sure whether we should produce them as our listed product, as the AF is rather unusable. The Metabones is good at least in the sense that aperture data can correctly be sent from the Sony camera to the Canon lens.
The port is made in 2 pieces. The main body first needs to be mounted onto the housing, then the lens with the adaptor can be mounted onto the camera through the front threaded opening. Finally the front part of the port needs to be secured onto the main body. There is a picture of a very similar port made for the same lens (but this time with a Canon EF-S to M adaptor) mounted on Canon Eos-M camera on the Nauticam USA site.
Due to the increasing interest in this combination we will start to produce them very soon.
We would like to know who is your dealer, and where are you from.
It is a surprise for us to know of your case from Wetpixel becuase we haven't heard such from any dealer. We are going to take this very serious as it is unacceptable for us that your case has not been solved for a month.
I regard the files from the new generation FX sensors in D4/D800/D600 are much more film-like in terms of smoothness (low-noise) and dynamic range compared to any digital cameras I used before. If you don't need 36 mp this camera is the best after D4 at very affordable cost. Only one very minor complain that the OK button in the center of the multi-selector is not customizable to have one-push zoom in during playback for checking focus.
It is lighter and smaller than D800 which is perfect for underwater. AF speed seems to be on par with D800. Everything etc is up to our expectation. Haven't spent much time with shooting movie yet. But have to caution that AF in video mode is still not quite usable.
I used 2 Inon Z240s for all photos set to S-TTL and triggered by the internal pop-up flash.
I did a break-in dive week in Bonaire a few weeks ago, I dove with a Subal and my dive buddy with a Nauticam for our D800s. Side by side the Nauticam looks larger then the Subal. Both were set up with Inon Z240 strobes, ULCS arms and Stix floats
We had a chance to put both Subal and Nauticam D800 housings side by side in the Dema show; and I can confirm that Nauticam is smaller on all three sides.
Not that I am saying any one of them is better, just a matter of fact. Different manufacturers have different philosopies in housing design, and I am glad there remain a decent degree of friendliness and respect among us, all major housing manufacturers, who are all working very hard to fulfil different demands in this small market.
