Yes, my NA-7DMKII housing is fitted with the Nauticam vacuum system. I had a third party vacuum system fitted to my old NA-7D housing before the Nauticam system became available. The Nauticam vacuum system is much better than the system fitted to the older housing, the Nauticam vacuum pump pulls the vacuum down much quicker, the vacuum can be released without having to reattach the pump and the warning light system gives a constant indication of the state of vacuum inside the housing. Happpiness is a nice green light shining on your housing.
Images are coming in the next few days.

Almost five years ago I was among the first to take the Canon 7D underwater using two different housings (an Aquatica on loan and my Nauticam) and posted a review of these two housings here on Wetpixel called:
With the release of the Canon 7D MkII and Nauticam NA-7DMKII housing late last year I decided it was time to upgrade from my well used Canon 7D/Nauticam NA-7D to the new arrivals from Canon and Nauticam. Once again finding myself amongst the first take this combination underwater I thought I’d follow up my earlier review with my thoughts on the latest versions. I received the new rig just in time to take on a trip to Ambon over the Christmas/New Year period and have now done 30 dives with the combination.
Canon 7D MkII
Rather than go into a pixel peeping, measurebating blow by blow review of the Canon 7D MkII (there are plenty of those out there on the web, eg here, here and here) I’ll just go through the features for underwater still photography (I don’t shoot video) that set it apart from the original 7D. For me there are three features that stand out, two relatively minor and one very important:
All other things being equal (and they aren’t, the 7D MkII is a much better camera all around than the original 7D) it is worth upgrading to the 7D MkII just for the new AF system.
Nauticam NA-7DMKII Housing for Canon 7D MkII
Since I started using my original 7D nearly five years ago I have watched with interest the improvements made in each new housing released by Nauticam since then. I’m happy to say that it appears that all these improvements and more have been incorporated into the new NA-7DMKII housing. Impressed as I was with the original NA-7D when I received it back in 2010 it had some shortcomings. I’m happy to report that apart from a couple of very minor quibbles the new NA-7DMKII housing is an exceptionally good housing with no real shortcomings.
The design, quality of manufacture and the finish of the NA-7DMKII is excellent.
A lot of thought has been put into minimising the weight of the housing, for example:
The ergonomics of the housing and location of controls is excellent:
Internal Flash Controls
I’m very happy to see a full set of controls on the NA-7DMKII housing to raise, lower and control the 7D-MkII’s internal flash. No more:
The NA-7DMKII has one button on the left side of the housing to raise the flash. Once the flash is raised, another press of this button takes you straight into the flash control menu so you can easily change the flash from manual to ETTL, change from first to second curtain sync, change manual flash power, etc, etc. There is a second control on the top of the housing next to the on/off switch which lowers the flash and disables it to enable shooting at shutter speeds faster than 1/250.
Image Review Controls
As previously mentioned the image review controls on the 7D MkII have changed a lot from earlier Canon DX dSLRs. The controls on the NA-7DMKII housing to perform image review are excellent and made it very easy to adjust to the new (to me) method of image review, these controls are:
Controls on Right Hand Side of Housing
The controls on the right side of the housing are:
Controls on Left Hand Side of Housing
Apart from the previously mentioned Image Review Lever and Raise Flash button the other controls on the left hand side of the housing are:
Controls on Top of Housing
Apart from the previously discussed White Balance/Metering Pattern and AF Drive buttons the other controls on top of the housing are:
Controls on Top of Housing
Buttons on the left hand side are:
All are easily accessed and operated using your left hand thumb.
Buttons on the right hand side are:
All are easily accessed and operated using your right hand thumb.
The Multicontroller is also located on the top right side of the back and is very easy to reach and operate with your left hand thumb. It is a huge improvement over the equivalent control on the original NA-7D which was located in the middle of the housing and couldn’t easily be reached without taking off your hand off the handle. It was partially blocked by the 180° magnifying viewfinder and the up button couldn’t be used. The Multicontroller on the NA-7DMKII is a dream to use in addition to moving up/down and left/right you can also control movement diagonally, makes moving your focus points around very easy. It also has a central button which returns whatever you are adjusting to the central position (great for returning you focus point back to the middle).
What didn’t I like about the NA-7DMKII? Not much, I have only a couple of very minor quibbles. Apart from the problem with the mode dial moving when putting the camera in the housing I mentioned above the only other issue I have is to do with changing out the CF memory card with the camera in the housing. On the original NA-7D housing the CF card could be easily changes without having to remove the camera from the housing. Because the NA-7DMKII has two memory card slots the CF card is now moved a few millimetres forward in the camera body to make room for the SD card. While the SD card is easily removed from the camera in the housing the CF card cannot be removed unless camera is unlocked and slid back a couple of millimetres.
From reading a lot of reviews of the Canon 7D MkII it appears that it is aimed at a particular market niche, wildlife and sports photography. As such it may not be everyone’s cup of tea for general photography and video. For what I do with it, underwater still photography, it is an excellent camera mainly due to its auto focus system. I am very happy with it.
I’ve been using housed film and digital SLRs since 1984 and have used seven different housings (Canon Marine Capsule, 4 x Subal, 1 x Aquatica and 1 x Nauticam) before purchasing the Nauticam NA-7DMKII. It is without a doubt the best housing I’ve owned. Exceptionally well made and designed. The ergonomics are superb and it is a dream to use underwater.
A very special thanks to the Nauticam distributor in Australia, Peter Mooney from Scubapix. He moved heaven and earth to get the Nauticam NA-7DMKII to me after it was released to in time for me to take it on my trip to Ambon. It only made into my hands with a few hours to spare before I left on the trip.

I've just got back from a trip to Ambon, Indonesia and used the 7D Mk II in a Nauticam housing for 30 dives during the trip. Having used the original 7D in a Nauticam housing for nearly 5 years the most notable improvement with the 7D Mk II is the autofocus, it is very fast, accurate and performs well in low light conditions that would have required a focus light with the original 7D. The Nauticam 7D Mk II housing is also excellent, by far the best housing I have ever used (it is the 8th housing I've owned). I am preparing a full review of both and will be posting it on Wetpixel in the near future.

Final note: The vacuum check system may extend all the way back to the 70's. I'm asking around to find out more....
I think you will find that doing a vacuum check to ensure that the seals on submersible enclosures are functioning correctly goes back a very long way. I spent a large chunk of my life as a Submarine Engineer Officer in the Australian Navy. The last thing we did before going to sea and diving after an extended period in harbour for maintenance was to close all the hatches, pull a vacuum inside the submarine and monitor over a period of time to ensure that none of the seals on hatches, periscopes etc were leaking air into the boat. This has been a standard maintenance procedure in submarines for a long time. If a vacuum check is good to keep me dry when the submarine dives (water in the people tank is not a good thing ) it's good enough to ensure my camera stays dry when I take it diving.

I think that the old larger cap will fit on the T4 strobes but not vice versa.
That's my experience. My wife uses Inon S2000 strobes (same connector as Z240 Type 4) with fibre optic cords off her old Type 2 Z240s. No impact on either manual or sTTL function has been noted.

I think Retra's web site was a little out of date when I ordered my Retra Pro. At that time the angled adapter was offered as an optional extra and I ordered mine without it. When I received it, it was fitted with the angled adapter.
The angled adapter is good in that it allows you to align the LSD so that the aiming light in the strobe is shining on the centre of the light collector in the LSD. This ensures that the beam from the aiming light is a bright as possible and accurately shows where the beam from the flash will fall. The only downside I found was that because the angled adapter is clear to allow you to align the strobe's aiming light on the light collector, it does allow some light from the strobe to escape. Depending on strobe position this can allow escaping strobe light to light the background of your shot. For example:
Although it can work to your advantage as shown in these two shots, in general it doesn't.
However it is easy to fix the strobe side leakage problem. Once I had determined the optimum position for the LSD on the strobe I put an alignment mark on the LSD and the strobe and covered the clear adapter with duct tape.

Fly direct to Manado via Silk Air (approx 3 hours from memory) and you can be diving in Bunaken and/or Lembeh.
I probably didn't word it quite right, Philippines I've been to once, and Bali I'm probably doing next year. I'm really just looking for something where I can jump off a direct flight from Singapore and jump into the water (more or less), stay there for a couple of days, then come home. Does such a place exist? Tell me if I'm dreaming!
