Nikon D850 & Nauticam NA-D850 Housing Review

By Jack Connick
Nikon’s new D850 full-frame camera is proving to be one of their most popular cameras ever, and what’s not to like? A massive 46MP sensor with resolution that matches or exceeds film, fast autofocus (AF) borrowed from the pro-level D5, low base 64 ISO to better capture bright scenes and a fast 7 fps frame rate with an electronic front curtain shutter, for just a start. Matching that are improved flash electronics, TTL protocols and 4K video. For those D800 and D810 underwater photographers who fell in love with shooting full-frame images, the upgrade is intriguing.

I’ve shot many different cameras underwater, from small compacts and several Olympus mirrorless models, to other Nikon DX DSLRs. The Nikon D500 (review here),  certainly is one of my favorites. Snappy performance and incredible low-light focusing make it ideal for many underwater photographers, especially for macro and black water. But I really fell head over heels in love with the incredible dynamic range of the full-frame D800. (See comparison article.) As slow and heavy as it was, it still solidly cranked out some amazing shots. But the technology and electronic features of these cameras changes quickly and I was ready for a faster, newer generation.

Heard, but Not Seen?

The new Nikon D850 FX camera hit the streets last fall, and while everyone has been waiting impatiently, due to its popularity and Nikon’s low production levels, most would-be buyers haven’t been able to find one. In a rare event, housings were available almost immediately. For my first trip to Fiji in December with the D850 it meant that I had to rent a body.

I use LensRentals.com a lot for these sorts of situations, as it’s a great way to “try before you buy” for cameras and lenses. By the time we left for my second trip to Yap and Palau this spring, I was able to buy a D850 body. Between the two trips, I now have around 60 dives on the new D850 and Nauticam housing system, and love it!


It’s Just Zippy

The D850 really is a different beast, owing more to the pro level D5 than anything else. It’s much faster all the way around – AF, electronic shutter, frame rate, buffer and processor. Just zippy. While the D800 felt and acted much more like a film camera, the D850 is much more modern in every respect. It feels a lot more like a cross with the mirrorless cameras in that way. There are also a lot of new features, such as a swiveling touch screen, that are very nice to use above water. Nikon also swapped the position of the ISO and Mode buttons, which was a great idea, as I tend to change ISO constantly when shooting an FX camera.

It does have several function buttons and custom settings, but they are not as programmable as the Olympus E-M1 MKII. That said, there are plenty of functions available to make your life easier underwater. For instance, assigning the flash sync setting to F2 allows you to switch from TTL to manual (by using 1/250th sec FP) when using the Nauticam Technics TTL board in the housing. I also assigned the “My Menu” selection to F1, which gives you fast access to the first item on the list.

Lens Quality & Calibration

The image quality (IQ) of the D850 is tremendous, but I struggled a bit to get the focus just right on my first trip to Fiji. It seemed to back focus a bit and trying to catch a single focus spot wasn’t always successful. I found that the uber-high resolution D850 requires the AF to be closely calibrated with lenses, as it less forgiving of lens quality and focus than other models.

Fortunately, most Nikons allow you to add a precise calibration adjustment to the camera for each of your lenses. I found that even with my wide angle Sigma 15mm FE lens, with a huge depth of field, a couple of small adjustments made a big difference in picture quality. Although Nikon has an automatic calibration routine to do this, I couldn’t get it to work consistently, and ended up using an old school set-up of shooting a ruler at a 45° angle.

Released at the same time, Nikon’s new 8-15mm FE lens seems to be the go-to lens for close focus wide angle shots, but after I got the Sigma calibrated, I found it shot very well on the D850 and is quite a bit less expensive. I shot it behind a Zen 170mm dome, which yields excellent corners and quality. Nauticam's 140mm FE dome has also been optimized for these lenses and is slightly smaller with a removable shade.

A popular configuration of the Sigma 15mm FE and the Kenko 1.4 teleconverter didn't work out well. The depth of field was very small, so trying to do a "wide angle macro" shot resulted in unpleasing out of focus backgrounds. The exceptional resolution of the camera desn't allow for much leeway.

For a mid-range zoom, I’ve used a 17-35mm lens for quite a while as I like it’s f/2.8 speed. On the D800, I could cheat a little and use the smaller 170mm dome if I cropped the corners of the photos.

Not so on the D850. Not surprisingly IQ was terrible with the smaller dome. For these mid-range zoom lenses, you have to use a large glass dome port – I used the Saga Dive 230mm (9”) dome along with a 70mm extension and zoom gear.

To further improve quality, I also used an internal Sea & Sea M77 Correction Filter to reduce distortion and soft corners even more. This is a little discussed piece of gear, but really improves these mid-range lenses. I felt the images turned out great with this combo. I actually liked diving with the larger dome port, it balanced the rig out and improved camera handling, and even in the higher currents found in Palau, I didn’t find its size to be an issue.

For macro, I use the standard Nikon AF-S 105mm VR macro lens for most situations. In Palau I tried shooting my Nikon 60mm Micro lens in order to gain reach while shooting sharks and big animals that were shy. I tried this lens behind my 170mm dome with an extension, and it turned out great - as long as the visibility was good, as you are stacking up water. I really liked the versatility of being able to grab shots of shy sharks, small schools of fish, and macro shots with this one set-up, and used it quite often.

Focusing In

A lot has been written about the D850’s AF speed and modes. Several photographers suggested using the camera in AF-C (continuous focus) mode, rather than AF-S (single focus) mode. I’m old school, and most of the times I try to dumb these cameras down to a single spot with AF-S focus mode. The D850 is one of the first cameras where I liked to shoot in group AF (other than macro) and with AF-C (continuous focus) activated. I hardly ever had an out-of-focus shot. It definitely is also fast to focus and worked well in low light situations. However, in my experience it’s a bit slower in low-light than the D500, but not by much.


Swing Low

As one might expect, the D850, like most FX cameras has just tremendous low-light capabilities and you can easily shoot at ISO 2000 or above with no issues. Coupled with it's much improved AF, it makes shooting in caves, or dark situations easily achievable with just available light. This is another one of the really great improvements it has over the older D800/D810 models.

Battery life is good, as you are no longer using a pop-up flash to trigger your strobes. With a fast 128GB XQD card installed, I did 4 dives or more without needing to change batteries or cards.

Live View shooting is much faster. Gone are the long delays, and at times I found it useful, although I like the bright optical viewfinder much better.

Video


I did shoot a bit of video. The camera has been improved to shoot in 4K, with many nice on-screen controls, like focus peaking. Whole sets of video controls can be set up and accessed at the flip of a switch.



Nauticam NA-D850 Housing

I also found many nice improvements and differences between the Nauticam NA-D850 the older NA-D800 underwater housings. Having used many Nauticam housings over the years, it’s great to see continuous improvement from model to model.

Not surprisingly, the new D850 housing is shorter than the D800 model, as there is no pop-up flash or tall “bell” to hold it. The width of the housing is about the same.

The biggest surprise to me was the weight difference – one full pound lighter! While all housings can be made to be more neutral underwater with the addition of floats, the mass remains the same. Swimming one less pound of mass around makes quite a difference in handling.

I was using two Sea & Sea strobes and shot a lot in TTL on both trips. However, I almost always shoot larger animals and other wide-angle in manual, as these situations don’t reflect enough light to the camera to adjust TTL triggering very well.

The newer Nauticam Nikon housings now use electronic Technics LED trigger boards that take up very little room, a manual version comes standard. I found the optional Nauticam TTL board and found it to be quite accurate – better than what I was used to when I had used the D800’s onboard flash. I could also adjust the ev on the strobes accurately. I normally shoot with  +.3 ev dialed in, as I almost always want a bit more light, and this gives the strobes a better TTL range.

For the most part, the TTL board was very accurate and determined good exposure. However, I found it vastly under exposed shots with too much contrast across the frame, such as an overhang with soft coral and a bright sky behind it. Switching to manual strobe control in those situations worked fine, and with the function button set up I could switch the strobes from TTL to manual, or even off/on, with a press of a button.

The rest of the controls on the Nauticam housing are designed with ergonomics in mind. Having produced housings since the Nikon D90, Nauticam has it figured out. They are all easy to reach and adjust, and fall right under your fingers, although I’d probably vote for the ISO lever to be a little bit more prominent; sometimes I couldn’t quite find it without looking.

As the D850 camera has a flip-up viewscreen, Nauticam matched that with a mounting tray that tilts the viewscreen to 15°, making it much easier to view.

Standard features include the famous rotating port bayonet lock and vacuum check system – now with a push button valve with a front reset button. These make diving much less stressful when taking such an expensive camera underwater.

There are a few important options that I would add to the housing. An external viewfinder (I use a 180°), to take advantage of the extremely large/bright optical viewfinder on the D850, the Technics TTL board, two housing ball mounts for lights, and a carrying handle along with a hand strap for a secure, one-handed grip).

Time to Upgrade?

So, is it worthwhile to upgrade from a Nikon D800 or D810 to this new beast - the D850? I struggled with this, as these FX systems are expensive, but my verdict is a decided yes.

The D850 camera is much faster, shoots easier, and has improved functionality with just plain incredible IQ all the way around. I like it much better than the D800, both above and below the water.

The new Nauticam housing adds even more to the mix; smaller, much lighter, with improved controls, electronic strobe capabilities, and vacuum leak check systems. The combination is extremely powerful.

The secondary market for used D800/D810s is remaining reasonably strong, so an upgrader can expect to outlay less than they think after all is done.

I feel the Nikon D850 is the upgrade that everyone has been waiting for and will redefine this pro-level camera market segment.

South Pacific Dreamin’ - Yap & Palau Trip Report

Dropping into the warm, crystal clear water we spotted at least 3 or 4 species of sharks all in good numbers. We were on a shark dive on the remote outer reef of the Micronesian island of Yap. Grey reef sharks of moderate size, lots of smaller black tip reef sharks and quite a few larger silvertips were nosing around us looking for their afternoon snack. Good for us it was a small “chumsicle” of frozen fish, which they eagerly attacked on the bottom. For the next 45 minutes we excitedly clicked away and enjoyed the show. While the sharks were definitely curious about us, they kept their distance. Certainly, a great dive.

After many hours of flights on through the night and day, fifteen of us had arrived early in the morning the day before to this small island paradise for the first stop in our 2018 OOS South Pacific Photo Expedition.


Manta Ray Bay Resort on Yap was very well-organized and had us in our rooms quickly and up and diving by late morning the next day. The hotel is getting old now, and while it could use some updating, was spacious and comfortable. Meals were taken in their converted wooden sailboat anchored permanently on-site. They were surprisingly good, with lots of choices, even pizza!

Yap Divers had excellent facilities featuring “VIP” service where they take complete care of all your gear other than your wetsuit. There was a large camera room, and rental dive gear was available. The guides were excellent, and nitrox fills were included in our 3 dives a day package.

The diving in Yap is nearly all hard coral on fringing reefs. This mostly necessitated long boat trips out through the mangroves, and winding channels along pristine coral reefs out to the blue.

The first day was somewhat cold and raining hard to our surprise. It meant we had to go pretty far out to get away from the run-off and green water. The hard coral reefs and walls were pretty, and the geography spectacular underwater, but besides fish, there was little invertebrate life or colorful soft coral. Still the dives were fun, well run and organized which made my job as group leader easy.

The next day we ran out to see if we could find some mantas, as Yap is noted world-wide for these huge gentle fish. The mantas there are mostly “reef” mantas, and smaller than the large pelagic versions, but quite numerous. Or so we’d been told. The green water runoff to the lagoon made visibility pretty poor and the mantas stayed home.

The following day we went back and after waiting nearly 45 minutes, we were finally rewarded with a couple of mantas dancing around our heads for 10-12 minutes and we nailed a few keeper photos. Along with the shark dive that afternoon, we had a great day of it.

After more dives in clear water, and a fun tour and picnic on the Manta Bay Resort’s private beach, we were ready for the next leg of our trip to Palau.

United Airlines in their wisdom has decided that you can’t just take the old short “hopper” flight directly from Yap to Palau. You now have to return to Guam, wait most of a day, and then fly to Palau. This is a lot less than convenient, and Guam is not my favorite place to hang out. And of course, the street in front of our airporter hotel was blocked by a once-a-year marathon race and we had a heck of a time getting to it.

But all the logistics worked out, and we arrived in Palau later that evening and were met and taken to the Rock Islands Aggressor for our week’s long trip around the islands there.

This was the second OOS Aggressor Palau trip and having enjoyed a great trip 3 years ago, it seems like Palau is one of those destinations that bear repeating. I think what is most interesting from a photographers’ perspective is the shear diversity of shots and situations you encounter, from pristine walls and reefs, sandy “bommie” covered bottoms, unique dives in German Channel, the caves and caverns of Blue Hole and Siaes Tunnel and world-famous high current dives on Blue Corner, Big Drop Off and outlying walls on Peleliu.

Besides all the great reef and wall diving, there’s also a multitude of WWII wrecks and every dive has surprises; sharks everywhere, mantas, eels, huge schools of every fish imaginable, and lots of macro and invertebrate life.

Which is pretty much what we enjoyed that week on the Aggressor! These boats are huge catamarans, created as dive boats and are very comfortable. We were short a few divers, so the fifteen of us spread out a bit in the eighteen-passenger boat.

The dive deck is a bit smaller than you’d think, as all the tanks and dive gear other than your mask and wetsuit, stays on the auxiliary hard boat dive skiff. Divers just walked on board the skiff, loaded up cameras and the skiff is lowered into the water on a hydraulic lift! No death-defying leaps into inflatables, or difficult to crawl up ladders. We also could all backroll into the water in two groups, which meant that we could get our entire boat load into the water in a couple of minutes. A definite plus for bluewater, high current dives.

They’ve gotten rid of the large circular camera table that wasted a lot of space and replaced it with 3 long tables with 2 shelves which work out much better. Besides a comfortable lounge and bar (with free beer and wine), there’s also dinette tables. Meals on the Aggressor have improved from their already good service to absolutely outstanding! Our chief prepared breakfasts to order, lunches with lots of great selections like sushi, pizza, salads, soups, and mouth-watering fine dining dinners served at your table. I felt like they had really stepped up their food from the last trip.


The cabins were generally comfortable, and the a/c now well controlled (many boats don’t have good thermostats). I think the only drawback to the layout of the Palau and Rock Island Aggressors is the old-style bunk bed cabins. They’re fine for couples, with a larger double below but for singles, they are uncomfortable as older customers don’t like the climb up to the narrow upper bunks. We also had some smelly holding tank issues with the boat showing its age, but, to be fair, it was going into annual maintenance the following week.

But back to the diving. One of the problems with Palau is that it’s a bit over-loved by close-by Asian nations. These groups tend to be culturally exclusive and use their own hotels, dive operations and guides. As groups they also aren’t usually the most experienced divers. The day boats have long rides in the morning and afternoon, so the good thing is that from a liveaboard it is easy to avoid these multitudes of divers by being able to dive earlier and later in the day. Or we could get to outlying dive sites, not accessible for the day from Korror.

For divers wanting a more remote experience, it’s getting harder to find on Palau. Several times we were over-run by these eager, but inexperienced groups, or had to wait for them to leave the sites before we could dive. But we got lots of dives in and were able to do 4 dives a day, with a few night dive opportunities as well.

We had an outstanding dive on Peleliu with the clearest visibility of the trip. We lucked out and were able to experience the once-a-year mating congregations of long-finned snappers with thousands of fish moving along the bottom of the wall like a freeway, then bunching up and forming a vertical mass. We had the same luck finding a once-a-month congregation of bump-headed parrot fish with hundreds of the large fish massing together and shooting to the surface spewing eggs and sperm. It all happened so fast it was nearly impossible to take photos of, but they were a very unique experience that we all enjoyed.


Blue Corner didn’t disappoint with lots of grey reef sharks swimming by, huge schools of jacks and a very gregarious and friendly napoleon wrasse hamming it up for photos. Siaes Tunnel (really a cavern) is deep, with the entrance at about 90’ but we were surprised by a large school of jacks hiding there and the four unique small macro fish were spotted, living nowhere else on the reefs.

Jellyfish Lake is still closed as the jellies have died off, originally due to drought or overuse, but now nobody is quite sure of the issues there. However, we had a great dive on the Jake Seaplane with good visibility in the lagoon, and we finished the trip with an excellent macro dive right outside of Chandelier Caves with lots of unique finds like mandarinfish, two-spotted gobies and pajama cardinalfish posing for our lenses.

Once back to Korror, the crew on the Aggressor dropped us off to a very nice new rooms at The Cove Resort until our trips home started that night. On the way back, a few us stayed over in Honolulu and enjoyed a quick trip to the Pearl Harbor Memorial for the morning. All in all, the 2018 OOS South Pacific Photo Expedition was a very successful trip with lots of great dives and hundreds of photos to edit!

A few D850 Shots from Fiji

Spent a week on the Nai'a and another 8 days at Qamea Resort near Taveuni.

Shot the Nikon D850 in a Nauticam NA-D850 housing. I used the Sigma 15mm FE, Nikon 17-35 behind a Zen 170mm dome, as well as the Nikon 105mm VR macro.

I'm still working on a TR, will post when it's available. But here's a few shots to whet your appetite.

Lembeh Straits Macro Video on a Nikon D500

I've (finally) edited together a video of macro critters from Lembeh Straits during last year's Photo Expedition to Dive into Lembeh resort. I used a Nikon D500 camera, 60mm macro lens, diopters in a SEA&SEA MDX-D500 housing with a Kraken Sports Hydra 5000 video light. It includes footage of a rare "Hairy Octopus". All shot hand held!

Saga Dive Trio Macro Lens Review

I love shooting underwater macro – specifically super macro. One of the challenges of this discipline is deciding on which diopter to bring along on a dive. Inevitably I choose one strength lens and wish I had brought along something different. Enter the Saga Dive Trio. This innovative lens from Spanish optics manufacturer Saga Dive, combines a +5, +10 and +15 diopter in one unit, giving you the ability to shoot anything from a fish portrait to a pygmy seahorse on the same dive.

On a recent trip to Anilao, Philippines  I was afforded the opportunity to put the Trio to the test. My rig was comprised of a Nikon D7100 housed in a Sea and Sea MDX-D7100 housing with a Nikon 105mm VR lens. I added the Trio via the 67mm thread mount on the front of my port. I was a bit concerned that the Trio might be a bit cumbersome or awkward underwater, however this was not the case at all. I did not notice much difference in buoyancy from my +15 diopter on a flip adapter. The system rotates to aid in camera/light positioning. I did add a very short arm to my focus light to assist with getting light directly in front of the lens. Magnification from +0 to +15 is managed by very simple pair of levers on the front of the lens.

Being in the critter capital of the Philippines provided an abundance of subjects. On my first dive with the Trio, my guide excitedly gets my attention. He has found a hairy shrimp. To the naked eye it looks like a tiny red spot of lint. Dropping down both levers to put the Trio at +15. I line up my shot. Click. Flash. I check my review screen and am thrilled with the result. After a couple more shots I switch places with my dive buddy who has found a beautiful, and bigger, nudibranch. By lifting up the right lever I am ready to shoot at +5. I could get used to this. During the course of the dive I used all the settings of the system. I found that to be case on every dive.

During the rinse down at the end of the day I was surprised at how much debris had accumulated between the lens and my port glass. Anilao is a mucky environment and there was quite a bit of sediment in the water column. For the rest of the trip I made it a point to take off the Trio between dives to give it a rinse. Problem solved.

Upon reviewing my images at the end of the trip I was very happy with the results I got from the Trio. I found the images to be quite sharp through the +10 setting. At +15 the edges tended to lose a small amount of clarity, a trade off I am willing to make in exchange for versatility. Having the ability to change magnifications so easily was very useful. It is hard to imagine going back to using a single lens for an entire dive. I would recommend the Saga Trio to anyone interested in macro photography. — Billy Ball

Review: Kraken Weefine Underwater Photo Ring Light

The latest offering from Kraken Sports is the WeeFine Ring Light for macro illumination. This innovative light attaches to any threaded port and is similar to ring flashes using strobe lights that have been on the market for a while. However, it features a constant-on 1000 lumen light and is small, lightweight and self-contained. As with all Kraken Sports products, build quality is excellent, with an even, high-quality output and well-designed anodized construction.

This light is intended for very close-up use. It has a nicely beveled center section that tapers to allow you to put the light over small subjects without hitting them. The battery holder and light swivels on the center section, so you can flip it around out of the way during the dive. By using step up rings, you can attach the light to almost any threaded port. I used it with both an Olympus PT-EP14 (67mm) and TG-4’s PT-056 (52mm) housing easily.

It’s 1000 lumen output has three power settings, and comes with a standard 18650 lithium battery and cradle charger. The switch bezel uses colored lights to tell you the remaining battery strength.

The Weefine Ring Light’s small, self-contained size, and nearly neutral weight, make it ideal for a macro camera rig with bright illumination that is “plug and shoot”, it’s as easy to use as taking photos above water.

On our recent Komodo Park dive trip, I shot it with the Olympus E-M1 MKII in the Olympus PT-EP14 housing and 60mm macro lens. One limitation I ran into is that you cannot add or remove a macro diopter lens underwater. You have to decide above water how much magnification you want to use. I used a +5 diopter, but it might be better to use a +10 or greater and shoot super macro.

There has been a lot written about taking photos using constant-on lights. The issue is not only lumen output, but longer exposures. Strobes are designed to put out a tremendous amount of light instantaneously that freezes motion and gives rich color saturation. A light just doesn’t give the same effect, unless it is very powerful and is used close enough that the color of the water doesn’t affect color temperature. By my eye photos taken with a light as compared to strobes look a bit soft and flat.

I found that on the Olympus E-M1 MKII slr,  the 1000 lumen power was weaker than I'd like to see for reasonable exposures. I had to use high ISOs along with slow shutter speeds for proper exposure, so image quality and sharpness suffered. Of course the smaller the subject matter the closer you can get and the better the exposures.

The ring light’s small size and constant exposure made shooting very quick. I got some good shots of a quickly moving small Wonderpus by being able to move in quickly and use the fast frame rate of the E-M1 without waiting for a strobe to recycle.

Light quality using any ring light is even and flat. This makes the Kraken ideal for scientific captures without shadows, but it’s not a creative lighting source that could add shadows and depth. Trying to tilt it one way or the other just made the shot evenly underexposed on one side.

I also shot the ring light with an Olympus TG-4 compact. This camera is well-known for its exceptional macro capability. It has a built-in strobe for macro, but the camera’s Super Microscope mode, that normally uses an LED light on the camera for illumination, is not available when inside a housing. The Kraken Ring Light works great as a substitute.

With the Kraken Weefine Ring Light, the TG-4 really came into its own for super macro photos. I used it in Program mode and selected a high aperture. It seemed to work better than the high-resolution E-M1, with a greater exposure latitude.

What was nice was that I could carry both two cameras together on a dive. The TG-4 and ring light was so small that I could clip it out of the way, while using the larger E-M1 strobe rig for wide angle, and then be able to switch to the TG4 for macro shots. I could easily place into tight spots that the bigger camera couldn't reach.

You can use the TG-4 to shoot more normal shots but you can't zoom all the way out to the widest lens setting. As such also you cannot use underwater Wide 1 mode which fixes zoom. The ring light obviously wouldn't work for illumination for those types of shots. The constant-on light would also be good for macro video use, although I didn’t get a chance to test it.

To get modest exposure times, I had to use the light on full power. I was only using a standard 1100mha battery on a prototype unit. As such, battery run time on the light was problematic.  Even turning it down between shots, I could only get 35 to 40 minutes from the light. This should be improved on the production model as Kraken will ship the light with a larger capacity battery.

In the end, I found that at 1000 lumens it’s not strong enough for slrs without compromising image quality unless shooting super macro.

For the best quality stills with any camera, a high intensity strobe will always give better results, however, they are larger and more expensive. For video, we normally recommend a minimum of 1200 lumens, so it’s dimmer most video lights.

I think the Kraken Weefine Ring Light is a small and relatively inexpensive ($229) lighting solution for macro photography, that produces decent results. Getting even, well-lit, super shots is effortless with it.
