Underwater Shooters Looking Forward to New Sony a7 FE Mount Wide Angle and Macro Lenses

Sea LionUnderwater photographers who travel and want a pro-level camera have been stuck with much larger, heavier full-frame DSLR camera systems. The choice was to compromise quality and capability for smaller size mirrorless cameras, or just deal with the extra weight, bulk and travel expense. In these days of add-on airline fees, this situation has been getting worse.

Earlier this year Sony changed all that with the release of the Sony a7 full-frame mirrorless camera. This is truely a game changing platform.

As I stated earlier in my review of this camera, the Sony a7 series are light, fast, incredibly customizable, and with a great sensor. The release of the high resolution a7r and the 4k capable a7s further reinforced this great lineup.

But they have very few lenses available for the their new FE lens mount. For some reason Sony seems to come out with a new mount every time they come out with an SLR. Alpha lenses don't fit. Of course they have adapters, but those are usually slow and the resulting lens stack won't fit underwater housings. And the price adds up.

The missing lenses for underwater photography are (surprise) macro and extreme wide angle. 

Sony has recently posted the 2015 roadmap of new lenses for their FE mount that fits the a7 series. 

The good news on this front is that starting mid-next year Sony/Zeiss will ship a 90mm macro lens (still not as powerful as I'd like to see for FX) and a 28mm wide angle with FE and W/A adapters - not a great solution, but a better option than the 35mm they have now. The venerable Nikonos 15mmFE manual lens probably still remains the underwater wide angle lens of choice for the Nauticam NA-7 housing. Hopefully Sigma and some others will jump into this FE mount vacuum soon.

Here's a quote from a Sony executive from dpreview
"...There are 13 lenses for the E mount currently but we still need to create more lenses to compete with other manufacturers. We’re catching up. One consistent request from our customers is macro lenses and wide-aperture lenses...."

The promise of a lighter, smaller, electronic full-frame SLR camera system is slowly being realized. In the meanwhile, I'll still be shooting my Nikon, with decades of glass available.

Reefs in Texas - Yee Ha!

Trip Report - Flower Garden Banks National Marine Sanctuary - July 2014 - By David Todd

Recently I had a chance to dive on some of the healthiest coral reefs in the world off the coast of Galveston, Texas in the Gulf of Mexico.

The Gulf is not known for it’s pristine waters. With two-thirds of the US draining into it, it tends to be muddy, filled with oil and gas platforms and wouldn’t be most people’s first choice when searching for a dive destination.

Those folks are missing out.

The Flower Garden Banks National Marine Sanctuary, one of thirteen Marine Sanctuaries administered by NOAA, contains 350 acres of some of the healthiest coral reefs in the world, with up to 55% live coral coverage. To put this in perspective, the coral coverage in the Caribbean averages in the teen percentages.

The reefs at Flower Garden and Stetson Banks are the Northern-most tropical reefs in the continental US and are part of the US’s National Marine Sanctuary system. The nearest tropical reefs are 400 miles south in Mexico.

Since they range from 80 to 110 miles offshore, they don’t get a lot of traffic from divers, in fact there is only one regularly scheduled live-aboard that services the area. Leaving from Freeport, Texas, about an hour from Galveston, The MV Fling holds and up to thirty divers and does two and three day trips to introduce folks to the “Texas Caribbean.”

You board at night and the vessel steams through the night to get out to these gorgeous reefs.
This trip is not for the faint of heart. It is somewhat advanced diving, both because of the depth of the reefs, average 65-75 feet for the top of the reefs and the variable strong currents that can occur at the bottom, mid water and at the surface.

Water entrances and exits are somewhat athletic, with a 6-foot giant stride entry and a trailing line exit to the ladder that can feel like a bit of a Nantucket Sleigh Ride when the surface currents are up. Also the dive masters on this boat are very thorough in their safety and site briefing, but they do not accompany you on your dives. You will want to be comfortable in your abilities to dive there.

Winter is the time for schooling Hammerheads and occasional Tiger sharks, but during our summer visit we were treated to Mantas and a school of 7 30+-foot Whale Sharks. Great Barracudas and large jacks accompanied us on every dive, sometimes in schools of over 100 fish.

In general, the Flower Garden Banks reefs are large colonies of coral of 25 different species, populated with large snapper, masses of Creolefish and grunts and an occasional Spotted Drum and other exotics as well as a host of gulf invertebrates from huge sponges to slate pencil urchins.

Stetson’s rocky terrain is often described as a moonscape; It’s upswept rocky ridges are home to large schools of Vermillion Snapper, Queen Conchs, the rare Golden version of the Spotted Trunkfish and a resident Sandbar shark, that we were lucky enough to watch in hunting mode.

Night dives at Stetson were equally as fascinating as the day, with all of the nocturnal animals like Beaded Sea Cucumbers, sea urchins, Slipper Lobsters and decorator crabs foraging over the reef while the day fish slept. We had to take care to not spotlight the sleeping fish in order to keep them safe from the hungry jacks that opportunistically use divers lights as a hunting tool.

In addition to the Flower Garden Banks and Stetson Banks, most trips also dive on an oil platform or two. This is truly a spectacular experience, as these massive steel structures form artificial reefs and are teaming with life, from tiny macro critters like blennies and gobies, bizarre alien fish like the large scrawled filefish and cowfish to schools of large pelagics like jacks and sharks. In fact, we had a great several minute visit from a curious Silky Shark while hanging on our safety stop at Platform High Island 389 which is known as one of the top ten oil platform dives in the world.

Needless to say, there were amazing opportunities for photography and videography on this trip. From big animals to macro it was there. However, I was there on a biological survey trip with a group of marine educators and photography took back seat to our surveying activities.

I was able to shoot a bit of video in which you can get a glimpse of some of the life there.

Sea of Cortez Sony a7 Underwater Video

We have a new video posted on Vimeo. Some various clips of whale sharks, bull sharks, wrecks, huge schools of fish and lots of fun from our June Photo Expedition on the Solmar V. Shot on the Sony a7 in a Nauticam USA housing with an old manual focus Nikonos 15mm FE lens. Viz was pretty challenging most of the time...and yeah, I mostly like to shoot stills...but this video thing is fun!

A Beginner’s Dilemma – Canon SL1 vs. Sony RX 100

by Bill Van Antwerp, President LACUPS
A couple of weeks ago someone suggested that the Sony RX100 generated far nicer photos than the Canon SL1. Having shot both of them on land, I was not convinced. However underwater it might be a different story. So thanks to Andy Sallmon our local Sea and Sea representative, I got the chance to take both diving near Catalina Island. The Canon SL1 is a digital SLR and the Sony RX100-II is a point and shoot with a similarly-sized sensor.

A comparison of the two cameras is shown below:

Sony RX100-II Canon SL1
Sensor 5472 x 3648 (20 MP) 5184 x 3456 (18 MP)
Format Still JPEG, Raw JPEG, Raw
Movie MP4, MPEG, H.264 MOV, MPEG-4, H.264
Memory Card SD, Sony Memory Stick Duo SD
Image Stabilization Optical Lens Dependent
Dimensions 4.0 x 2.3 x 1.5 4.6 x 3.6 x 2.7
Weight 281 g 370 grams
Lens (as shot) Zeiss 28-100 (35 mm equivalent) Canon 60 macro
Sync speed 1/1000 1/250
Shutter Lag 372 ms (with flash) 102 ms (with flash)
Viewfinder Electronic Optical
Smallest Picture Size 76 x 51 mm 23 x 15 mm
Price $648.99 $649 (with 18-55)

The Canon SL-1 was set up with the Canon 60 mm macro lens and the RX100II of course had only its beautiful Zeiss lens with no wet diopters. I know this is an unfair comparison of the two systems, but that is what I had and that is what I shot.

Sea & Sea housings were used for both; the MDX-RX100/II and the RDX-100D. These were paired with twin Sea & Sea YS-D1 strobes, shot in TTL mode with RAW photo capture mode.

Now, I am a dedicated macro guy, I love to shoot little stuff, particularly nudibranchs, but on this day at least, there were no nudis to be found on the front side of Catalina. There were however a bunch of garibaldi around including some juveniles and for little stuff comparison, there were a bunch of blue-banded gobies. 

For comparison purposes all files were opened in Lightroom (5.6) with the punch preset of Clarity +30 and Vibrance of +25.

The first photo is a close up of a garibaldi from the SL1.

Photo 1: Garabaldi from Canon SL1

Figure 2 is a garibaldi from the RX100. The conditions were not quite as nice but you can see that the color balance from the RX 100 is quite good.

Figure 3 is a ubiquitous blue banded goby shot with the Canon

Figure 4 is the same blue banded goby with the Sony. 
Photo 4 from Sony RX-100II
Figure 4 shows a lot of green algae next to the goby; this is not a flaw of the camera but rather is the color of the reef where this was shot. The differences in the magnification are significant but that is more due to the fact that I used the Canon with the 60 macro lens.

Figure 5 is a juvenile garibaldi with the SL1

and figure 6 is a slightly older garibaldi shot with the RX-100II.

In the RX-100 shot, the green tint can not be easily removed and still keep the garibaldi, more or less perfectly exposed.

I also got to shoot the RX-100 in the Sea and Sea housing with the D1 strobe at an indoor pool function with beginning discover students.

Conclusions: If you are starting out underwater and are looking for a first system, either of these cameras will help you get great underwater shots. The Sony is a great little camera, but occasionally in our quite green Southern California waters there was a little color-cast that was impossible to remove. Shooting the same types of scenes with the Canon (and the exact same strobes), led to more neutral colors.

The advantages of the Sony are it's small size and the ability to shoot both wide and macro on the same dive, if you have the appropriate add-on lenses.

The advantages of the Canon are that you can shoot much smaller subjects without an add-on lens in a really small, compact package.

For me as a macro/super macro photographer, the Canon is by far the preferable package. You can of course add on a wet diopter to the Sony, or even stack them, but the starting point for magnification is about 11 times less area.

At the end of the day, both cameras performed very well underwater, both housings were a joy to use, and both cameras took very nice pictures; you won’t go wrong with either choice.

Join Us for Humpbacks, Sharks, Mantas & More!

March 10-18th, 2015; Socorros Photo Expedition on the NEW Nautilus Belle Amie!

The Revillagigedos Islands, also known as the Socorro Islands, are located 250 miles offshore southwest of Cabo San Lucas, Mexico. They form an oasis for pelagic life amongst their volcanic shores. Many hammerhead and silky sharks, giant manta rays, dolphins, sailfish, schools of jacks and tuna come to feed, mate and get cleaned by small endemic Clarion Angelfish.
These animals tend to be quite friendly towards divers at times, allowing for fantastic interactions and blue water photo opportunities.

Giant Mantas: The giant Pacific mantas which you will meet at Socorro are the largest of the rays and we believe they are the most majestic creatures in the ocean. They swim by moving their wing-like pectoral fins, which can grow up to 7 meters wide, but usually average about 5 – 6 meters. What is even more extraordinary is that the local population of bottlenose dolphins have learned to mimic the behaviour of the giant mantas. It is very likely that these wild dolphins will also move in close and intimate to divers during your trip.

Shark sightings are also very good at Socorro Island with common sightings of silky, galapagos, hammerhead, white tip and silver tip sharks.

Humpback Whales: Optical Ocean Sales has organized this trip to go at a perfect time of year to see migrating Humpback Whales. A population of 1200 humpbacks moves into the island’s waters in early spring and chances are excellent that you will have encounters with these mighty giants. You may even hear them singing through the hull of the ship at night as you lie in your bunk.

Optical Ocean Sales: Owner Jack Connick (making his 4th trip to the islands), will help you get the most of your underwater photo opportunities.

New Nautilus Belle Amie Liveaboard: At 140' in length and 300 tons, the Nautilus Belle Amie redefines luxurious diving. Staterooms are located on three decks and are very spacious with en-suite heads and twin beds and no bunk beds! Three high-speed rigid inflatable 28' dive skiffs are loaded on/off the stern, you just step on and off, your gear is ready! A hot tub and bar complete the upper deck, with a comfortable saloon and dinning room and another bar on the wheelhouse deck.

The ship is stabilized, fast and comfortable in a seaway. In fact, it's the only boat to offer 6 full days of diving on a week's trip! Departs beautiful Cabo San Lucas, Mexico.

Spots on this trip start at only $3355. Read more and sign up in the store Download our flyer!
