Nauticam has released its newest aluminum underwater camera housing, NA-G7X for the 20MP Canon G7 X Camera. The NA-G7X is the latest release in the Nauticam advanced compact camera lineup, and provides an impressive feature set for underwater photographers seeking big image quality in a small package.
The Canon Powershot G7 X
The G7 X was one of the most interesting introductions of September’s Photokina Imaging Fair in Cologne, Germany. This camera is a serious competitor to the hugely popular Sony Cyber-shot RX100 series cameras with a large 1″ image sensor in a truly pocketable form factor. The size of the G7 X is reminiscent of the Canon S-series of high end compacts, a model which has also been very popular for underwater photography, but sports an impressive 2.8x larger sensor. Digital Photography Review suggests: “The G7 X is just as small as the Sony RX100 but offers much more in terns of direct control.”
The G7 X is a true enthusiast camera built around a 20 megapixel 1” BSI CMOS imaging sensor and updated DIGIC 6 Image Processor. Image quality is nothing short of exceptional.
To make the most of these digital chops, G7 X sports an outstanding lens, covering an extremely versatile 24-100mm equivalent range. This is just as wide, but with more reach than competing compact options. The lens is also very bright, with a maximum aperture of f/1.8 on the wide angle end, and only closing down to f/2.8 at full telephoto.
Most interesting to underwater photographers is the excellent macro performance of G7 X when used with accessory macro conversion lenses. G7 X can capture significantly smaller subjects than Sony’s RX100 series. Nauticam say that the only current cameras that they have tested offering better closeup performance are the smaller sensor Canon G16 and S120.
The display panel is a 3” TFT-LCD, and is articulated, allowing a full 180 degrees tilt for shooting in tricky circumstances.
As expected, 1920 x 1080 Full HD movie clips can be captured at 30 or 60 fps and enhanced by Canon’s very accurate underwater white balance capability, producing pleasing color when shooting movie clips with only a filter.
Canon’s determination to compete with the best in the compact camera market means we all reap the benefits.
NA-G7X is the latest iteration in a lineup of advanced housings for very capable compact cameras supported by Nauticam. Features found on professional DSLR systems have been integrated into this system, and the result is an underwater housing that allows the user to harness the full potential of advanced compact camera in water.
All of the basic functions and ergonomic enhancements that Nauticam users have grown to know and love are incorporated in NA-G7X. The housing is machined from a solid block of aluminum, then hard anodized to seal out corrosive salt water. It is closed via a simple, yet secure locking rotary latch. The right side of the housing is sculpted to fit the palm of the user’s hand, and Nauticam’s two-stage shutter release lever provides clear differentiation between the half press and full press shutter release positions. All functions are clearly labeled, and an m14 accessory socket allows an optional vacuum valve to be installed.
This is the first Nauticam compact camera housing to feature an interchangeable port system. This new port line is called the “N50” mount, and allows optical solutions to be precisely dialed in for maximum performance in water. Ports are attached via a bayonet fitting, and locked securely in place.
The Nauticam leak alarm and vacuum monitoring system is installed as standard equipment. This system provides an audible and visual alert to any water entry in the housing, and when combined with an accessory M14 Vacuum Valve (#25611) the water tight integrity of the system can be tested before ever entering the water and monitored during every dive.

- Sculpted, sensitive shutter release
- M14 bulkhead port for vacuum valve
The New N50 Port System
Because of the specific camera and lens function of the Canon G7 X, a special port system is required to fully realize the potential of accessory wide angle lenses underwater.
The NA-G7X “standard” port, supplied with the housing, allows full zoom through and features a 67mm threaded front for attaching accessory macro lenses. This port is ideal for mid-range fish portraiture style shooting, close-up, and macro with add on wet-lenses.
An optional N50 Short Port with M67 Thread for Wide Angle Lenses (#38701) is available, offering precise placement of wide lenses very close to the camera’s lens at its wide angle zoom position. Zoom through is not available with this port, but it does offer the widest coverage possible with minimal vignetting for wide angle photography.
A dome port solution is also available, restoring the in-air field of view of the lens. This is a light weight configuration that offers a surprisingly wide angle of coverage. This port is called N50 3.5″ Acrylic Dome Port (#38702).
Testing indicates that the Inon UWL-H100 (either in the m67 mount or the LD mount) is an ideal wide angle lens for the NA-G7X. This combination will result in a diagonal FOV in excess of one hundred degrees (100º).
Nauticam Vacuum Check System
The engineers at Nauticam have also managed to squeeze in the Nauticam vacuum monitoring and leak detection electronics. By default, it serves as an audible and visual leak detector, but add a Nauticam M14 Vacuum Valve, (p/n 25611) and it becomes a vacuum check system. The vacuum monitoring system provides early warning for any problem with watertight integrity – which means peace of mind when shooting underwater.

Exhibition: Protecting UNESCO Marine World Heritage through scientific research
From now until 30 October, the photo exhibition “Protecting UNESCO Marine World Heritage through scientific research” features 21 photographs at UNESCO Headquarters, Paris, as well as a digital edition.
Exceptional photographs highlight how innovative marine experts and scientists take the pulse of the ocean by exploring ecosystems, studying the movement of species, or revealing the hidden biodiversity of coral reefs. Scientific discoveries are more important than ever for the protection and sustainable conservation of our Marine World Heritage. This memorable exhibition comes ahead of the launch, in 2021, of the United Nations Decade of Ocean Science for Sustainable Development (“Ocean Decade”). The exhibition was jointly developed by UNESCO and the Principality of Monaco.
The 50 marine sites inscribed on the UNESCO World Heritage List, distributed across 37 countries, include a wide variety of habitats as well as rare marine life still largely unknown. Renowned for their unmatched beauty and emblematic biodiversity, these exceptional ecosystems play a leading role in the field of marine conservation. Through scientific field research and innovation, concrete actions to foster global preservation of the ocean are being implemented locally in these unique natural sites all over the world. They are true symbols of hope in a changing ocean.
Since 2017, the Principality of Monaco supports UNESCO to strengthen conservation and scientific understanding of the marine sites inscribed on the World Heritage List. This strategic partnership allows local management teams to benefit from the results obtained during the scientific missions of Monaco Explorations. The partnership also draws international attention to the conservation challenges facing the world’s most iconic ocean sites.
The exhibition invites viewers to take a passionate dive into the heart of the scientific missions led by Monaco Explorations in four marine World Heritage sites: Tubbataha Reefs Natural Park (Philippines), Malpelo Fauna and Flora Sanctuary (Colombia), Rock Islands Southern Lagoon (Palau), and the Lagoons of New Caledonia: Reef Diversity and Associated Ecosystems (France). It is also an opportunity to discover the work of a megafauna census; the study of the resilience of coral reefs and their adaptation in a changing climate; the exploration of the deep sea; and the monitoring of large marine predators through satellite data.

Deptherapy returns to its Roots – Part 7
Join Richard Cullen from Deptherapy for the final part of his Blog about the charity’s recent expedition to Roots Red Sea, El Quseir, Egypt.
Deptherapy expeditions do not just magically happen, they need planning and they need funding. This expedition was funded by our long-term partners the Veterans’ Foundation. The funding is part of a grant they awarded us for programmes this year, which were then put on hold because of COVID.
All charities in the Armed Forces’ Sector are struggling for funds. Deptherapy desperately needs support going forward and every penny counts.
We know what we do works and at the end of this blog you will find details of the research studies into Deptherapy’s programmes and how they impact on the lives of our beneficiaries. This includes details that are hot off the press about the latest study that reports that what we offer through scuba diving and 24/7 support has benefits beyond those found in other sporting rehabilitation programmes.
Well tomorrow we fly home, late in the evening with the journey home for some of the guys who live up North taking around 15 hours after leaving Roots.
We want to make the most of today but with the tide running we are not going to be able to dive until later this morning which means only two dives today.
Things, however are really busy over at the dive centre with Swars and Oatsie putting their sidemount kit together for their training dives with Steve Rattle leading to their RAID sidemount qualification. It has been nice to be able to offer the guys this extra training, given the amount of work they have put in this week. They have needed to get through their theory quickly but given the RADI online learning system this has not been too arduous.
Steve came diving with us yesterday to get some more photos and was really amazed at the progress that Corey had made. He was quite open in his praise, as in his view Corey has gone from a non-diver to being a very competent OW diver capable of diving, unsupervised, with a buddy. Praise indeed.
Other than the sidemount course we are diving as a group today: Corey, Keiron, Michael, Moudi and me. Corey has been given some tasks – SMB deployment on both dives and the afternoon dive will be a ‘naturalist dive’. Guy Henderson has set Corey a task: ‘to identify three species of fish and record the time into the dive and the depth at which each one was spotted’. Guy runs Marine Biology courses on the reef and knows where the fish are to be found, how long into the dive, and at what time.
The two Toms are getting put through their paces. They have walked their cylinders down to the entry point, but Steve sends them back to the dive centre to collect other kit they should have brought with them.
Our general dive goes well and the sidemount guys appear from their sidemount dive some 90 minutes after dipping their heads under the water.
Lots of bubbly chat at lunchtime, a group of really happy divers. Corey really has benefited from the week and over lunch thanked the team for making him a diver. He has very quickly become part of the family and after returning home he published an amazing post on Facebook about his experience. Corey really gets Deptherapy and had soon realised that we see past mental and physical injuries and see the person inside and work with that person. He also realised that we want beneficiaries to see their fellow beneficiaries in the same light. He knows he now has another ‘family’ – a family of brothers in arms who have two things in common, they served their country and they have suffered life changing injuries or illnesses.
Back into the water for the afternoon dive and Corey identifies the fish and records the details on a slate. The two Tom’s complete their second dive and qualify as RAID Sidemount Divers. Great!
Kit packed away and it is time to return to the camp for a few well-earned last night drinks.
I am often asked why we use Roots as our exclusive base for diving. I have mentioned before that it offers us an ideal retreat, away from the hustle and bustle of everyday life. We are secluded and there are no distractions such as late-night bars etc.
The second reason is the amazing welcome we receive from Steve, Clare, Moudi and the team. We have been going to Roots since 2014 and many of the staff have become good friends, they understand our needs and are the friendliest people you could ever wish to meet.
The third reason is the huge investment Steve and Clare have made in making the resort and dive centre accessible for those with physical injuries including those who need to use wheelchairs. All our beneficiaries can enjoy Roots and, in fact, love it here. The reef is perfect for us and in non-COVID times we can travel to the Salem Express and other dive sites to enjoy more of the Red Sea experience.
After discussions with the team I was very proud to be able to tell Corey that his progress had been such that we were inviting him on the Armed Forces Covenant Fund Trust sponsored two-week Marine Biology Course at Roots in June 2021. There is lots of homework to undertake under the guidance of Dr Debbie McNeill of Open Oceans and Corey will be sent the Red Sea Guide which is the basis for study.
While on that programme, Corey with fellow beneficiary Dale Mallin, will complete his RAID Advanced 35 course. This all builds to a 10-day Red Sea liveaboard in 2022, onboard Roots’ new boat Big Blue where 18 beneficiaries will compare the coral and aquatic life on the wrecks of the SS Thistlegorm and the less known SS Turkia that is to be found in the Gulf of Suez and is rarely dived.
Paul Rose, our Vice President, is supporting the programme and is seeking the support of the UN and the Royal Geographical Society. A comprehensive report will be submitted to our partners in the project and to the Egyptian Authorities.
What we do works:
In recent years there have been three academic studies into our work:
2018 – A study by a team from the University of Sheffield Medical School.
2019 – A study by The Centre of Trauma at Nottingham University.
Both these studies reported very positively on Deptherapy’s work both underwater but also in terms of the provision of 24/7 support.
The following is from our press release which was issued on 26th October:
‘A new study into Scuba Diving Rehabilitation Charity Deptherapy’s approach to supporting Armed Forces veterans with psychological injuries such as Post-traumatic Stress Disorder (PTSD) through the medium of scuba diving has been carried out by Petra Walker in conjunction with Hanna Kampman of the Posttraumatic Growth Research Unit at the University of East London.
This study, which used Interpretive Phenomenological Analysis (IPA), demonstrates that scuba diving has rehabilitation benefits beyond those found in other forms of sporting rehabilitation exercise. IPA is a qualitative methodology that examines the experiences of participants and has been used in previous studies of Posttraumatic Growth (PTG) in para-athletes.
Petra is an experienced diver herself and was exploring the wellbeing aspects of scuba diving as part of her Masters in Applied Positive Psychology and Coaching Psychology when she came across a previous study on Deptherapy. Past studies have mainly focused on the medical aspects of diving, so the opportunity to examine the mental health side of rehabilitative scuba diving was impossible to ignore. The full study is currently embargoed until it is published at a future date in an academic journal, but it follows similar academic research into the work of Deptherapy by the University of Sheffield Medical School (2018) and the University of Nottingham (2019).’
This is amazing news and sets us apart from other sporting rehabilitation programmes.
We are currently working with our VP Richard Castle who is a Consultant Psychologist and our Dive Medicine Advisor Mark Downs to identify further areas of psychological and physical dive related research.
We end the week on a happy note. A young man who has learned to dive properly with a RAID OW 20 certification, a new RAID Master Rescue Diver, two new RAID Sidemount Divers, 5 new RAID O2 Providers, many assessments for our DMs but most of all a week of learning, of making new friendships, renewing old friendships, and building on our family ethos.
For us, Deptherapy is a journey, a journey that continues to push boundaries in the use of scuba diving in the rehabilitation of those suffering life changing mental and/or physical challenges. On our journey we want to change the way the scuba diving industry views diving for those with disabilities.
In the new year, we will be launching, with our diver training agency partners RAID, a new and exciting adaptive teaching programme that will offer diving to the disabled community. We can’t wait to share it with you!
