Retra Announces Flash Pro Max II
Retra has announced a new version of its top-of-the-line strobe—the Flash Pro Max II. The fifth-generation strobe—coming two years after the fourth-generation Flash Pro Max, Flash Prime+ and Flash Pure—improves on its predecessor in key areas, according to Retra.

First, as you might have guessed, it’s significantly more powerful, packing 190 Watt-seconds (Ws) of output, up from the 140Ws of the Pro Max. Retra says that translates to “65% more actual light output” because the new strobe features a redesigned reflector, “optimized” power handling, and a better triggering system, where less energy is lost to heat. According to the company, recycle times have been improved by 25%, and at “low” power settings, it’s possible to shoot continuously at up to 60fps.

Other aspects have been improved, too: The target light is twice as bright as before (1,000 lumens as opposed to 500 lumens), the power dial now offers 17 positions (instead of 13), and the strobe even starts up faster. As previously, the battery compartment accepts four AA batteries as standard, plus an additional four AAs when the Booster is added, but the strobe, battery cap and Booster all now boast gold-plated contacts. Retra says you’ll get up to 2,000 flashes at 25% power using the 8×AA configuration.

If all that wasn’t enough, Retra are sweetening the deal for their launch offer: If you pre-order now, you’ll get a Booster and two USB chargers free of charge. Shipping from June 30th, the Retra Flash Pro Max II costs $1,800 with the standard three-year warranty, with the option to extend the warranty to five years for $50 extra.

New Singapore Oceanarium on Sentosa Opens in July

By DPG Editorial Staff, May 26, 2025 @ 07:00 AM (EST)
Source: Straits Times

Singapore isn’t just home to Asia’s biggest dive show, ADEX. It’s also where—come July 23rd—you’ll find one of Asia’s largest attractions devoted to educating the public about the ocean and its inhabitants. The new Singapore Oceanarium—a rebranding and upgrade of the previous facility, S.E.A. Aquarium—will be about three times larger than its predecessor and will feature 22 zones. The oceanarium is part of Resorts World Sentosa, situated on the island of Sentosa in southern Singapore.

While the centerpiece of the oceanarium remains the Open Ocean exhibit—an almost five-million-gallon enclosure containing sharks, rays, and thousands of other marine animals, and featuring a 120-foot underwater viewing panel—various new exhibits have been added. Among these is Ocean Wonders, home to one of the world’s largest Kreisel tanks, which is specially designed to house over 5,000 thousand moon jellies. Another is Whale Fall and Sea Mount, a deep-sea zone that uses immersive sights, sounds and live deep-sea habitats to educate visitors about how a whale fall becomes a life-giving oasis.

“More than just a new name, Singapore Oceanarium represents a bold transformation into a world-class ocean institute that inspires deeper knowledge, love and action for our oceans,” states the Resorts World Sentosa announcement. To serve that goal, the oceanarium aims to “push the boundaries of marine research” through partnerships with top academic institutions, including the National University of Singapore and the Earth Observatory of Singapore at Nanyang Technological University. In addition, a research and learning center, adjacent to the oceanarium, will provide “advanced facilities for scientists and researchers to conduct valuable research work and drive marine science outreach on-site.”

Resorts World Sentosa will soon be releasing information about forthcoming programs—and ticket prices.

Keldan Announces Video 4XR and Video 8XR Lights, and RC2 Remote Control
Known for their high-end—but not especially compact—video lights, Keldan is addressing the demand for travel-friendly gear with the release of three significant products: the RC2, a diminutive version of their RC1 wireless remote control; and two handy remote-controllable lights, the Video 4XR and the Video 8XR.

Like its bigger sibling, the RC2 works wirelessly underwater but is shorter range: 2–3 meters (6.5–10 feet) as opposed to the 50-meter (165-feet) range of the RC1. As such, it is designed for lights mounted on the camera rig or placed within a short distance from the remote. Like the RC1, the new model has two independent brightness channels, each of which can address any number of lights simultaneously, and works with all lights in Keldan’s “XR” series.

With the new Video 4XR, Keldan hasn’t just upgraded their popular Video 4X light with a remote receiver; the new version also has a higher lumen output—11,000 lumens rather than 10,000 lumens. While the 4XR replaces the 4X in Keldan’s lineup, the previous version of the 8XR—which boasts a 20,000-lumen output and a color rendering index (CRI) of 86—sits alongside the new 8XR, which has a slightly lower output of 17,000 lumens but a significantly higher CRI of 96. According to Keldan, the high CRI makes the new 8XR the perfect light for shooting macro.

Available soon from retailers such as Backscatter, the RC2, Video 4XR 11000lm CRI86, and Video 8XR 17000lm CRI96 are priced at $640, $1,970, and $2,650, respectively. There are also now various bundles available, such as dual Video 4XR and RC2 for $4,280, and dual Video 8XR 17000lm CRI96 and RC2 for $5,640.

Panasonic Announces Lumix S1RII with 8K Video
It’s been more than five years since Panasonic launched their Lumix S1R and Lumix S1 full-frame mirrorless cameras with an emphasis on photography and video, respectively. Now the follow-up photo-centric model—the Lumix S1RII—has finally landed, and there are few similarities between the old and new cameras. Built around a new 44.3-megapixel BSI CMOS image sensor and L² image processing engine, the S1RII is significantly smaller and lighter than its predecessor—so we can expect a slew of new underwater housings.

Promising the “best photos” of any Lumix camera, Panasonic says the new sensor offers a stop better noise performance as well as improved color rendering. Like other recent Panasonic cameras, the S1RII boasts Phase Hybrid AF featuring 779 phase-detect AF points as well as AI-powered subject detection and tracking. Using the mechanical shutter, you get an impressive 10fps burst shooting with continuous autofocus, while the electronic shutter offers 40fps. Another significant improvement is the in-body image stabilization, which delivers up to eight stops of shake reduction with shorter lenses or seven stops with compatible telephoto lenses. It’s worth noting that the camera’s maximum flash sync speed is now 1/250s, which is—unfortunately—inferior to its predecessor’s 1/320s.

On the video side, the specs are equally impressive: The S1RII is the first Lumix camera to record 8K/30p 10-bit video with 14 stops of dynamic range. The camera can also record internal Apple ProRes RAW HQ/ProRes RAW 5.8K to a CFexpress Type B card (albeit with an APS-C crop)—another first for the Lumix S series. Other recording options include (oversampled) 6.4K open-gate video for flexible cropping and reframing, and (subsampled) 4K/120p slow-motion capture. Serious videographers will also appreciate the advanced video assist tools, including waveforms and vector scopes for exposure and color monitoring, and real-time LUTs.

To round things off, the S1RII has dual card slots (CFexpress Type B, UHS-II SD), support for external recording to an SSD, a 5.76M-dot OLED EVF (0.78x magnification) and a 1.83M-dot 3-inch vari-angle rear LCD. The camera uses the same battery as the S5II/S5IIX.

Available now from retailers such as Backscatter, the Panasonic Lumix S1RII is priced at $3,300.

Environmental Photography Award 2025 Winners Announced

Overall winner – “Unseen Unsung Heroes”: Winner, Ocean Worlds by Angel Fitor

The 2025 Environmental Photography Award winners have been announced—and the Grand Prize Winner is an intriguing underwater image. Shot by Angel Fitor, the winning photo in the Ocean Worlds category, called “Unseen Unsung Heroes,” is a fascinating capture of polychaete worms flushing sand out of their burrows on a seagrass bed in the Spanish Mediterranean. The worms maintain oxygen circulation in the upper layers of sediment, a crucial role that allows a whole ecosystem to thrive under the substrate. At a global scale, the unsung activity of these perpetually hidden worms has significant consequences. Fitor says his winning shot “portrays the silent actions of humble creatures that nonetheless have a pivotal influence on the entire Mediterranean marine ecosystem—an ecosystem upon which we, in turn, depend.”

Honoring photographers who raise awareness about environmental issues and spotlight environmental challenges, the annual Environmental Photography Award was founded in 2021 to celebrate the Prince Albert II of Monaco Foundation’s 15th anniversary. This year, a prestigious jury of environmentalists, conservation photojournalists and filmmakers—including well-known names Ami Vitale, Aaron Gekoski and Ralph Pace—selected winners in five categories: Polar Wonders, Into the Forest, Ocean Worlds, Humanity versus Nature, and Change Makers: Reasons for Hope. Impressively, Fitor also won the Change Makers: Reasons for Hope category with an image showcasing a baby loggerhead sea turtle in a Spanish recovery center. Two more of his images were shortlisted in the Ocean Worlds category. In the Polar Wonders category, the winning image was also shot underwater: Galice Hoarau’s capture of a lion’s mane jellyfish in the frigid waters of Greenland.

To see the full gallery of winners, head over to the Environmental Photography Award website.

“Training Day”: Winner, Change Makers: Reasons for Hope by Angel Fitor

“Jellyfish and Iceberg”: Winner, Polar Wonders by Galice Hoarau

“The Passenger”: Runner-up, Ocean Worlds by Pietro Formis

“Coho Salmon in a Log Structure”: Runner-up, Into the Forest by David Herasimtschuk
