Nauticam Announces Housing for the Panasonic GX8

Published

on

Nauticam has introduced the latest in its line of underwater camera housings, the NA-GX8, designed specifically for the Panasonic GX8.

The Panasonic Lumix DMC-GX8

Panasonic continues to push the m4/3 envelope, this time with a new sensor that breaks into the 20 megapixel realm, the highest of any m4/3 sensor to date. This camera is aimed squarely at the enthusiast, with it’s excellent image quality, higher resolution, rangefinder styling and 4K video capture. It is an ideal camera for the underwater photographer/videographer.

The GX8 also features “Dual IS”, i.e. image stabilization in both the lens and sensor; working in concert to handle camera shake better than any previous Panasonic camera. More importantly for underwater image makers – focus has been improved considerably, especially in low light. Panasonic claims quick and accurate autofocus at -4EV. This should make focusing easier underwater, given that u/w scenes are typically darker than terrestrial scenes. The camera body features 3 command dials, including a dedicated exposure compensation dial.

Panasonic Lumix DMC-GX8 Features

  • Rangefinder-style mirrorless
  • Sensor CMOS m4/3 5184 x 3888 (20 megapixels)
  • Auto, 200-25600 (expands down to 100) ISO
  • Articulated LCD
  • 1.1M dot OLED
  • 2.4M dot EVF
  • 4K or HD video, mpeg4 or AVCHD
  • 4K burst photo modes at 30fps
  • 6 fps still photo with continuous AF

Nauticam NA-GX8

The pioneering features of the earlier Nauticam housings are apparent with the simple but secure rotating housing latch and superb progressive shutter release providing optimal “feel”. The NA-GX8 also sports some of Nauticam’s latest technology with the port locking latch that replicates the famous Nauticam DSLR port latch – making housing port changes easier than ever.

The new housing takes full advantage of the Panasonic’s many features and allows easy one handed operation of key controls like the three command dials and the video record button. The NA-GX8 supports 7 programmable buttons on this camera, easily accessible from the housing. The sculpted shutter release makes “half-press” focus incredibly easy. For fans of “thumb focus” (moving the autofocus from half-press of the shutter to a button operated by the right thumb), this is fully supported with the AF/AEL button.

Attention to detail is everywhere, from the comfortable thumb rest on the right to the large knurled command wheels and zoom/focus knob. Video is easily accessed; the video button is given special treatment, being larger, concave and red in color. For tripod use, the housing features two standard 1/4″ 20 tripod holes, or is also tripod ready when using the Flexitray W camera tray.

Strobe firing is supported via fiber optic through the use of the optional Panasonic DMW-FL70-S flash unit. Accurate automatic flash exposure (TTL flash) is easily accomplished via strobes like the Inon Z-240 or S-2000.

The NA-GX8 comes standard with the Nauticam vacuum system electronic built in. By default, it serves as a audible and visual leak detector, but add a Nauticam M14 Vacuum Valve, (25611) and it becomes a vacuum check system – early warning for problems with watertight integrity – which means peace of mind when shooting underwater.

Each control on the housing is clearly labeled, making it easy to learn the system. Milled from solid aluminum, the housing is rated to 100m/330ft depth, and is rugged and ready for use.

Nauticam’s rotary locking latch mean secure yet easy access to changing batteries or memory cards.
The Nauticam Port Locking Lever is easy to use and more secure than other methods of attaching ports. No twisting required, just push & lock. Worry less about the port attachment, and focus on getting great images.
Green means Go! The Nauticam vacuum check system provides an extra safety check helkping to insure a watertight seal every time.
The housing ergonomics are perfectly engineered for a “right hand on the grip” shooting style. Some users, especially those diving in cold water with dry gloves, need alternate ways to hold and operate the camera.This included shutter release extension and stainless steel handle bracket provide convenient shutter release access when used with the Nauticam Tray and Handle Systems.

Lenses

It’s all about the glass – lenses are the key to terrific photography. The m4/3 system supports a large range of high quality lenses produced by Panasonic (partnering with Leica), Olympus and third parties. Several lenses that perform extremely well underwater are available (and reasonably priced). Some examples:

  • Olympus M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ: The ultimate jack of all trades tool, this lens covers a very usable mid range, and features a unique macro mode. Shoot dolphins and nudibranchs on the same dive!
  • Panasonic Lumix G Fisheye 8mm/F3.5: This 180º fisheye lens focuses close and is razor sharp. Combines with a small port, there is no better CFWA (close focus wide angle) option on the planet.
  • Olympus M.ZUIKO DIGITAL ED 60mm f/2.8 Macro: This is an ideal macro lens for m4/3, and by adding the Nauticam CMC, it becomes a super macro monster. Imagine filling the entire width of the frame with something only 8mm wide!
  • Panasonic Lumix G Vario 7-14mm f/4.0 ASPH: The 7-14mm is a rectilinear lens, ideal for shooting people or sharks or wrecks… subjects where the fisheye distortion is not welcome. On the wide end, this lens 114º wide, ideal for getting close to subjects to reduce the amount of water shot through. But a zoom gets to 75º – ideal for reaching out to that subject that is a little more skittish. The very similar Olympus M.Zuiko Digital ED 9-18mm f/4.0-5.6 can serve the same basic role at a lower cost.

There are many more options for the underwater photographer, including any of the several 14-42mm options, the Panasonic Lumix G X VARIO 12-35mm F2.8 ASPH. POWER O.I.S., Olympus M.ZUIKO DIGITAL ED 12-40mm f/2.8 PRO, Panasonic Lumix G Vario 12-32mm f/3.5-5.6 ASPH, Panasonic Lumix G 14mm F2.5 ASPH, and the Leica DG Macro Elmarit 45mm F2.8 ASPH. Olympus also recently released two new wide angle lenses that are superb for underwater use, the Olympus M.ZUIKO Digital ED 8mm f/1.8 Fisheye PRO and the Olympus M.ZUIKO Digital ED 7-14mm f/2.8 PRO.

Nauticam Vacuum Check System

The Nauticam vacuum check and leak detection system electronics are included with the NA-GX8 as standard equipment.  Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe to dive status of the housing. The operator can, at a glance, instantly see the water tight and safe-to-dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The NA-GX8 features a 2nd bulkhead port (M14) specifically for installing optional vacuum valves, leaving the other bulkhead port for HDMI, sync cables and other accessories.

The NA-G8X, fitted with vacuum valve; the green light indicates a consistent vacuum and is an extra assurance that the system is watertight. Show with optional Flexitray, demonstrating the brackets and off board shutter release. 

Inon Z-240 Strobe Panasonic DMW-FL70-S Flash

Flash Connectors for Inon S-TTL

Reliable automatic flash exposure is available with the NA-GX8 and a variety of optically fired flashes. The Inon Z-240, D-2000, S-2000 strobes provide automated lighting, precisely reproducing the camera’s onboard flash at a proportionally greater intensity. This system yields accurate automatic TTL flash performance – even in manual mode – with no electrical sync cables to flood. The NA-GX8 comes fiber optic ready and accepts standard Sea & Sea style bushing connections.

Strobes can be attached to the housing via optional strobe mounting balls secured to the handles of the Nauticam accessory tray systems or a single strobe mounting ball location on the housing. The housing also features an M10 mounting hole and a cold-shoe mount for a focus light or other accessory mounting options.

NA-GX8 fitted with the optional 45º enhancing viewfinder.

Viewfinders

The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the ease of a magnified viewfinder with adjustable diopter. Nauticam produces a special version of its enhanced viewfinders made specifically for it’s new line of mirrorless camera housings. Whether it’s the “straight” 180º enlarging viewfinder (32204) or the 45º angled enlarging viewfinder (32205), the enlarged and brighter view enables easier focusing. Both viewfinders have high quality optics, and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools.

Northern Red Sea Reefs and Wrecks Trip Report, Part 3: The Mighty Thistlegorm

Published

on

red sea

Jake Davies boards Ghazala Explorer for an unforgettable Red Sea diving experience…

Overnight, the wind picked up, making the planned morning dive a bit bumpy on the Zodiacs to the drop point on Thomas Reef. There, we would dive along the reef before descending through the canyon and then passing under the arch before ascending the wall with a gentle drift. The site provided great encounters with more pelagic species, including shoals of large barracuda, tuna, and bigeye trevally.

Once back on the boat, it was time to get everything tied down again as we would head back south. This time, with the wind behind us, heading to Ras Mohammed to dive Jackfish Alley for another great gentle drift wall dive before then heading up the coast towards the Gulf of Suez to moor up at the wreck of the Thistlegorm. This being the highlight wreck dive of the trip and for many onboard, including myself, it was the first time diving this iconic wreck. I had heard so much about the wreck from friends, and globally, this is a must on any diver’s list. Fortunately for us, there was only one other boat at the site, which was a rarity. A great briefing was delivered by Ahmed, who provided a detailed background about the wreck’s history along with all the required safety information as the currents and visibility at the site can be variable.

Kitting up, there was a lot of excitement on deck before entering the water and heading down the shoreline. Descending to the wreck, there was a light northerly current which reduced the visibility, making it feel more like the conditions that can be found off the Welsh coast. At 10m from the bottom, the outline of the wreck appeared as we reached the area of the wreck which had been bombed, as our mooring line was attached to part of the propeller shaft. Arriving on deck, instantly everywhere you looked there were many of the supplies which the ship was carrying, including Bren Carrier tanks and projectiles that instantly stood out.

We headed around the exterior, taking a look at the large propeller and guns mounted on deck before entering the wreck on the port side to take a look in the holds. It was incredible to see all the trucks, Norton 16H, and BSA motorcycles still perfectly stacked within, providing a real snapshot in time.

red sea

Overall, we had four dives on the Thistlegorm, where for all of the dives we were the only group in the water, and at times, there were just three of us on the whole wreck, which made it even more special, especially knowing that most days the wreck has hundreds of divers. Along with the history of the wreck, there was plenty of marine life on the wreck and around, from big green turtles to batfish, along with shoals of mackerel being hunted by trevally. Some unforgettable dives.

The final leg of the trip saw us cross back over the Suez Canal to the Gobal Islands where we planned to stay the night and do three dives at the Dolphin House for the potential of sharing the dive with dolphins. The site, which included a channel that was teeming with reef fish, especially large numbers of goatfish that swam in large shoals along the edge of the reef. These were nice relaxing dives to end the week. Unfortunately, the dolphins didn’t show up, which was okay as like all marine life they are difficult to predict and you can’t guarantee what’s going to be seen. With the last dive complete, we headed back to port for the final night where it was time to clean all the kit and pack before the departure flight the next day.

red sea

The whole week from start to finish on Ghazala Explorer was amazing; the boat had all the facilities you need for a comfortable week aboard. The crew were always there to help throughout the day and the chefs providing top quality food which was required after every dive. The itinerary providing some of the best diving with a nice mixture of wreck and reef dives. I would recommend the trip to anyone, whether it’s your first Red Sea liveaboard in the Red Sea or you’re revisiting. Hopefully, it’s not too long before I head back to explore more of the Red Sea onboard Ghazala Explorer.

Northern Red Sea Reefs and Wrecks Trip Report, Part 2: Wall to Wall Wrecks

Published

red sea

Jake Davies boards Ghazala Explorer for an unforgettable Red Sea diving experience…

The second day’s diving was a day full of wreck diving at Abu Nuhas, which included the Chrisoula K, Carnatic, and Ghiannis D. The first dive of the day was onto the Chrisoula K, also known as the wreck of tiles. The 98m vessel remains largely intact where she was loaded with tiles which can be seen throughout the hold. The stern sits at 26m and the bow just below the surface. One of the highlights of the wreck is heading inside and seeing the workroom where the machinery used for cutting the tiles are perfectly intact. The bow provided some relaxing scenery as the bright sunlight highlighted the colours of the soft coral reef and the many reef fish.

red sea

Following breakfast, we then headed to the next wreck, which was the Carnatic. The Carnatic is an 89.9m sail steamer vessel that was built in Britain back in 1862. She ran aground on the reef back in 1869 and remains at 27m. At the time, she was carrying a range of items, including 40,000 sterling in gold. An impressive wreck where much of the superstructure remains, and the two large masts lay on the seafloor. The wooden ribs of the hull provide structures for lots of soft corals, and into the stern section, the light beams through, bouncing off the large shoals of glass fish that can be found using the structure as shelter from the larger predators that are found outside of the wreck.

red sea

The final wreck at Abu Nuhas was the Ghiannis D, originally called ‘Shoyo Maru,’ which was 99.5m long and built in Japan back in 1969 before becoming a Greek-registered cargo ship in 1980. The ship then ran aground on the reef on April 19th, 1983, and now sits at the bottom at a depth of 27m. Heading down the line, the stern of the ship remains in good condition compared to the rest of the hull. The highlight of the wreck, though, is heading into the stern section and down the flights of stairs to enter the engine room, which remains in good condition and is definitely worth exploring. After exploring the interior section of the ship, we then headed over to see the rest of the superstructure, where it’s particularly interesting to see the large table corals that have grown at the bow relatively quickly considering the date the ship sank. After surfacing and enjoying some afternoon snacks, we made sure everything was strapped down and secured as we would be heading north and crossing the Gulf of Suez, where the winds were still creating plenty of chop.

red sea

The next morning, it was a short hop to Ras Mohammed Nature Reserve for the next couple of days of diving. The 6am wake-up call came along with the briefing for the first site we would be diving, which was Shark & Yolanda. The low current conditions allowed us to start the dive at Anemone City, where we would drift along the steep, coral-filled wall. These dives involved drifts, as mooring in Ras Mohammed wasn’t allowed to protect the reefs. As a dive site, Shark & Yolanda is well-known and historically had a lot of sharks, but unfortunately not so many in recent years, especially not so early in the season. However, there was always a chance when looking out into the blue.

red sea

The gentle drift took us along the steep walls of the site, with plenty of anemone fish to be seen and a huge variety of corals. It wasn’t long into the dive before we were accompanied by a hawksbill turtle, who drifted with us between the two atolls before parting ways. Between the two reefs, the shallow patch with parts of coral heads surrounded by sand provided the chance to see a few blue-spotted stingrays that were mainly resting underneath the corals and are always a pleasure to see. With this being the morning dive, the early sunlight lit up the walls, providing tranquil moments. Looking out into the blue, there was very little to be seen, but a small shoal of batfish shimmering underneath the sunlight was a moment to capture as we watched them swim by as they watched us.

red sea

Towards the end of the dive, we stopped at the wreck of the Jolanda where the seafloor was scattered with toilets from the containers it was carrying. This provided a unique site to make a safety stop, which was also accompanied by a large barracuda slowly swimming by, along with a hawksbill turtle calmly swimming over the reef as the sun rays danced in the distance.

For the next dive, we headed north to the Strait of Tiran to explore the reefs situated between Tiran Island and Sharm El Sheik, which were named after the British divers who had found them. We started on Jackson before heading to Gordons Reef, where we also did the night dive. All the atolls at these sites provided stunning, bustling coral reefs close to the surface and steep walls to swim along, which always provided the opportunity to keep an eye out for some of the larger species that can be seen in the blue. Midwater around Jackson Reef was filled with red-toothed triggerfish and shoals of banner fish, which at times were so dense that you couldn’t see into the blue. Moments went by peacefully as we enjoyed the slow drift above the reef, watching these shoals swim around under the mid-afternoon sun.

red sea

The night dive at Gordon’s Reef was mainly among the stacks of corals surrounded by sand, which was great to explore under the darkness. After some time circling the corals, we came across what we were really hoping to find, and that was an octopus hunting on the reef. We spent the majority of the dive just watching it crawl among the reef, blending into its changing surroundings through changes in colour and skin texture. It’s always so fascinating and captivating to watch these incredibly intelligent animals, in awe of their ability to carry out these physical changes to perfectly blend into the reef. Before we knew it, it was time to head back to the boat to enjoy a well-deserved tasty dinner prepared by the talented chefs onboard.

Check in for the 3rd and final part of this series from Jake tomorrow!
