I know nothing about 10bar and it's accessory use on Nauticam.
I assume the DeoTech you refer to is a Canon to Sony adapter like the Metabones. The Nauticam ports that work with these adapters are the Nauticam Canon 60 port (like I have) or the Zen model which will work with both the 60 and 100mm Canon macros (with the correct outer port). Nauticam has said they'll support the Sony 90 as soon as it comes out for the FE A7 series housings. While not announced, I suspect also for the NEX platform at some point.
In the meantime the S90 may work in their Canon 60 port with 40mm of extension (two 20'). I'm hoping this is the case as I imagine the native port for the Sony macro will be quite expensive if they include manual focus and auto/manual control knobs. Since it's an autofocus lens and one can turn it on and off with the camera controls, maybe it'll just be a simple 2 part port which would make it more affordable. More or less how I will use it in my Canon 60 port. Too bad the S90 is 2mm wider than the ID of their focus gear for the C60 or I might have been able to get the port to do manual focus on the S90.
The Sony FE macro is supposed to be available in July, so we'll see soon enough what will or will not work..
Good luck with your 10bar ideas. I wouldn't think much, if anything, would cross over to Nauticam.
Since it may be some time before I finalize the attachment of a Nauticam 25105 swing mount to the 4.33, I thought I'd share the rig with you now, as it may be months before I finish it.
Currently as seen, the NA-NEX7 housing uses 3 lens: a modified Z12, S18-55 and the Canon 60EF-s macro in a custom Nauticam Canon 60 port with manual and auto focus (slow but accurate). The diopters are a F.I.T +5 and an Aquatica +10 that can be stacked if need be. I'd like to check out the new SMC-1 or CMC-1 in the future, but the ones I have are paid for :-) The Z12 is in the 4.33 and there's a close up showing it's glass element sitting back right about where the dome begins (optimum configuration). A 30mm extension might work too for both it and the S18-55, but I only have a 20mm and it works fine, especially better for macro when using the kit lens at 55 to shorten distance to the diopter.
The focus/video light is an iTorch Pro 6 with white, red and UV lighting. I configured a 52mm filter mount to the front (using home depot plumbing parts) to hold dichroic filters for fluorescent and video work. I bought the Nightsea light, but sold it because the iTorch Pro has pure UV and enough Lumens to give me blue light using dichroic filters. It's a great WA video and focus light too with removable batteries ( I carry 3 charged batteries). The Nightsea was brighter for sure, but not enough for me to carry both lights, plus the expense, not to mention no extra batteries. I also have dichroic filters for both the Inon Z-240 and S-2000. As you can see, I made a swingable 67mm filter holder for the Z-240 and implemented a 52mm filter holder onto the S-2000 diffuser holder. These filter holders give me lots of options on a single dive.
67mm lens/filter holders were attached to the float system to carry accessories. The S-2000 uses a mirror to fire (I can also use an optical cable) and it's on a detachable handle, so I can set it behind the subject for rear lighting.
The swing macro mount shown (Nauticam # 25104) is for my Port 72. In order for it to be grafted onto the wings of the 4.33, I'd have to do some modifications since the distance between the hinge system is about 5mm or so too short. A much better swing mount is the Nauticam 25105. It's about 7mm wider than the 25104 since it's made for the 4" semi-dome and the 67mm mount extends farther out since it's designed for a dome, not a flat port like Port 72. I believe this mount can be attached to the wings of the 4.33 with very little work, other than some stainless screws and spacers, no need to change the width of the hinges, etc. like with the Port 72 #25104. Basically the close up shows how the ring can be removed and hinges fastened to the wings of the 4.33. These mounts have a couple notched positions that allow the mount to be swung back in place, well out of the way when using the port for WA.
As mentioned earlier, the Canon 60 port is a 2 part port and wide and long enough (w/40mm of extension) to handle the Sony 90 FE macro. At least as far as my computations go, so I hope to replace the C60EF-s with the longer macro when it arrives. Or have both should the water be a bit mucky and I'd rather have a shorter macro to lessen the water between the subject and lens.
The entire system, including batteries & chargers, dive computer and filters fits into an Airport Antidote v 2.0 backpack (16 x14 x 9) which meets American Airline requirements for a personal item, so you can still take a carry-on with you. It weighs about 25 lbs. which works with AA and JAL, but one needs to move stuff to other areas (like the carry-on or photographer's vest) for most Asian discount airlines at 25 lbs is over the limit for a personal item or carry-on.
Did some preliminary tests with my modified Z12 in the 4.33 and 7" domes. I also ran the S18-50 in the 4.33 for comparisons. The big surprise came when I saw how good the S18-55 looked in the 4.33. Good sharp corners at 18mm and I was able to get good magnification with my Aquatica +10 diopter when holding it in front of the face of the dome with the S18-55 at it's longest 55mm reach. The lens at 55 was about a ¼" away from the inside face of the dome when using a 20mm extension.
The big surprise came when I compared the Z12 in both domes. Corner sharpness held up very well in the 4.33, quite comparable to the 7". It appears that dome curvature is not such a critical factor with the 4.33 and 20mm extension. Better yet, the close focus range with the lens in the 4.33 was so close, I must have been ½ to ¾" away for good focus. The close focus distance in the 7" dome was good too, but the lens is set back much farther in the larger dome and thus less magnification for CFWA shots.
The tests were preformed in my hot tub using it's textured pebble wall for sharpness comparisons. It was a sunny day under natural light so I could use a high shutter speed and still test all f-stop variations. Seems like the lens worked best in the dome at F8 and 11. I haven't totally completed the test comparisons and want to try a repeat shoot-out at the lens and domes sweet spots to make sure the results I was seeing was correct. The reason I want to test again is because the S18-55 was as sharp as the Z12, so a 2nd test is called for with both domes. I always felt I had an extremely good copy of the kit lens, but didn't expect it to hold up against the Z12.
My gut feeling tells me I'm going to sell the much larger Nauticam 7" and stay with the 4.33 and adapt a 25105 flip mount to it's wings so I can shoot 18 WA and 55 SM in the same dive with the kit lens. Not to mention, it's a much smaller and more compact travel rig with the 4.33. Now I'm curious how the new CMC might work with this set-up. I like my Aquatica +10 because it's fairly small and light compared to the larger SLR models. It will have to be positioned very close to the dome to eliminate vignetting though. I had to be careful not to scratch the dome when trying to center it during the tests.
I've attached a couple photos of the modified Z12. Zeiss removed the glued on faceplate for me so I could dismantle the bell shaped shade holder. I replaced it with a series of filter holders and step up/down rings to create a new shell that fits inside the 4.33 dome and still has the 67mm filter ring. This allows me to filter the Z12 for video and for fluorescence imagery when using the 4.33. Plus, the 4.33 works well with the S16, WA and FE converters, Sigma 19 and SZ24. I suppose I might keep my S16 and FE converter for wreck video, etc. So, it nice to have such a choice of lens with only two domes: the 4.33 and Canon 60 macro.
I'll keep you all updated on the 2nd tests and any progress I make on adapting the 25105 flip mount to the 4.33 dome.
I've also pre-ordered the new S90 FE macro and hope it will fit into my Nauticam Canon 60 macro port with the addition of two 20mm extensions. The math works out, so I'm hopeful. If not, I feel Nauticam will come up with a custom 2 part port for it. Anyone who has a 20mm extension I can buy or experiment with when the Sony 90 arrives, please PM me.
I'll post some photos of the rig when I get it completely modified for you Moray Eel.
Thanks for the info. It's always interesting to see how NEX users adjust to the lens situation.
Picked up a N7" dome off SB last week for a good price. When it arrived, I was sort of shocked by how much bigger it is than my 4.33! Better than those huge 8 & 9" SLR monsters, but still BIG in comparison. At least now, I have both domes to do side by side comparisons for the Z12 and S18-55, especially for corner sharpness. I'm really hoping my Irish luck holds out and I get the same results out of the Z12 and S18-55 in the N4.33; I definitely don't won't to add the N7 to my compact travel rig. Wish I had a Z16-70 to compare with the other lens.
I also wondered how the longer Sony zooms would work, as I know a diver who uses a similar AOV zoom in a Nikon set-up with a diopter and he likes it as a versatile single dive set-up for WA and SM. While the 18-105 is an internal focus, it's a power zoom, so no way real way to use it and it's width would require a 2 part port set-up. Like you said, the MFD really doesn't work and there's no zoom gears or means to activate such.
Photos released this week by a guy on the web shows the S90FE, side-by side to the C100L, both being almost exactly the same size. This has increased the odds it might fit in my 2 part Nauticam Canon60 macro port with a 30mm extension. It's even possible the focus gear will work. Keeping my fingers crossed.
Too bad the Z16-70 zoom gear is wider than the mini-port extension ID, as 50mm of extension (which I'll have) is the correct length to put the Z16-70 into my N4.33. Even if I did get a gear to fit, I have no idea whether this would even work with the dome optics, since the Z16-70 has a pretty long reach. Sure would be nice to try it though. The S16 works fine with the 4.33, so I'm hoping the Z12 and S18-55 will work better than expected.
I'll be posting some 100% blow-ups of the Z12 and S-18-55 in both domes for comparisons shortly.
