Overview

The DEMA Show is the largest trade-only event for the scuba diving, ocean water sports, and adventure/dive travel industries. With 500+ exhibitors and 7,000-9,000+ professionals from 60+ countries, it is the primary venue where underwater photography and videography gear manufacturers announce new products, and where the underwater imaging community gathers to network, socialize, and share ideas.

DEMA is where many of the most significant underwater photography products have been announced, including Nauticam’s debut (DEMA 2008), the Inon D-2000 strobe with S-TTL (DEMA 2004), the Sea & Sea YS-D3 Lightning (DEMA 2019), and the Nauticam Wide Angle Corrector Port (DEMA 2017). Major underwater imaging exhibitors have included Nauticam, Sea & Sea, Ikelite, Backscatter, Aquatica, Isotta, Keldan, Subal, Seacam, Gates, Light & Motion, and Inon.

Within the show floor, the Imaging Resource Center (IRC) serves as the hub for underwater photography and videography, featuring exhibitor booths from imaging equipment manufacturers and a schedule of seminars and presentations by leading underwater photographers and filmmakers. ([1])

Wetpixel at DEMA

Wetpixel covered DEMA extensively from its earliest years, producing some of the most comprehensive booth-by-booth show reports available anywhere. Eric Cheng personally attended and reported from DEMA 2000 through 2009, often with multi-hundred-photo galleries covering every imaging exhibitor. After Cheng’s departure, Adam Hanlon continued the tradition of exhaustive DEMA reporting from 2010 through 2022, with Abi Smigel Mullens, Drew Wong, and other contributors assisting.

DPG/Wetpixel Underwater Imaging Party

Since 2006, Wetpixel and DivePhotoGuide have co-hosted the annual Wetpixel/DivePhotoGuide Underwater Imaging Party at DEMA. Originally called the “Wetpixel Happy Hour” or “Wetpixel Cocktail Night,” it grew into what has been described as “probably the single largest gathering of underwater image makers in the world.” ([2]) The event has been held every year the show was active, evolving from drinks at a restaurant (2006) to a pool party (2011) to large-scale events at show hotels.

Wetpixel Booth

Wetpixel maintained a booth at DEMA from at least 2009 (booth #1068) through 2010 (booth #1344), staffed by team members representing Wetpixel Quarterly and the website. ([3], [4])

Year-by-Year Coverage

DEMA 2000 (January, Las Vegas, NV)

The earliest DEMA in Wetpixel’s archive. The digital underwater photography market was in its infancy. Products shown included prototype housings from Aquatica (for the Nikon D1, adapted from their F5 housing), Ikelite (housings for Nikon Coolpix 800, Coolpix 950, Kodak DC-290, and Sony Mavica), EWA-Marine (soft bags for Sony Mavica), Video-Sea (housing for Olympus C2020 with external strobe), and Nexus (planning a D1 housing). Ikelite was the most prolific digital exhibitor. ([5])

DEMA 2001 (January, New Orleans, LA)

One of Wetpixel’s first articles documented this show. Light & Motion dominated with their award-winning Tetra housing booth. Ikelite showed the DS-125 prototype strobe and housings for Canon G1, Nikon CP880, CP990, and Canon S100 Elph. Seacam displayed a Nikon D1 prototype housing. Sea & Sea showed the YS-90DX digital strobe with pre-flash setting. Epoque and 10bar also exhibited digital housings. ([6])

DEMA 2002 (October, Las Vegas, NV)

The year digital photography dominated. The show report was headlined “Digital Photography Dominates DEMA 2002.” Nine DSLR housings were shown and over 60 digital products were counted on the floor — a dramatic increase from the previous year when only Ikelite was fully committed to digital. Nearly all manufacturers who had been wary of digital cameras had “jumped in with both feet.” Bonica was the only photographic holdout unwilling to take risk in the “volatile” world of digital photography. The Nikon Coolpix 5000 was the most-housed digital camera with seven different housings found. David Breitigam and Eric Cheng co-authored the report, with Cheng photographing industry luminaries. Key exhibitors included Sea & Sea (new D-30/60 and D-100 SLR housings, YS-90 Auto strobe), Light & Motion (Tetra for Nikon CP5000 with built-in strobe control, prototype D-100 housing), Ikelite (new digital strobes, Fuji S2 Pro SLR housing), Seacam (production D1x housing, announced Fuji S2/D100/1Ds/1V housings next), Aquatica (CP5000 and D100 housings — the D100 was held up by U.S. customs as a “possible national security risk”), and Backscatter (MacroMate underwater lens). Gates hosted a book signing by Howard Hall and Brian Skerry. ([7], [8], [9])

DEMA 2003 (October, Miami, FL)

The digital SLR revolution continued. The Canon Digital Rebel (first sub-$1,000 DSLR) and Canon EOS 1Ds (first 10+ megapixel production DSLR) housing debuts stole the show. Eric Cheng and James Wiseman spent days covering every booth. Key products: Ikelite Canon Digital Rebel housing prototype; Aquatica Digital Rebel housing (using old F90 chassis); Sea & Sea DX-D10 Canon 10D housing with new 6-pin bulkhead for E-TTL and prototype Canon 1Ds housing machined from solid aluminum (built-to-order, engraved nameplate for buyers); Seacam Canon 1Ds, Nikon D100, and Fuji S2 Pro housings with the coveted S-180 viewfinder; Subal full lineup including 1Ds, 10D, D100, S2 Pro, CP5000/5400, and Canon G5 housings; Inon D-180 and Z-220 strobes; Backscatter Athena glass dome ports; and Olympus C-5060 announcement. Cheng noted that “very few of the pros” had not switched or planned to go digital. ([10], [11])

DEMA 2004 (October 13-16, Houston, TX)

Held at the George R. Brown Convention Center. Film products had virtually vanished from the show floor — aside from two Nikonos repair booths and a Kodak booth. Eric Cheng, Craig Jones, and James Wiseman produced a 25+ exhibitor report with nearly 300 photos. Key products: Inon D-2000 strobe ($509 retail) with S-TTL, replacing the D-180; Ikelite eTTL converter and housings for Canon Digital Rebel, Nikon D70, Olympus C-8080; Aquatica Nikon D70 housing with redesigned metal handles and sacrificial zincs; Seacam Canon 1D Mk II/1Ds Mk II housing with improved thumb-lever access to AF-ON button; Subal prototype Nikon D2X/D2H housing and ViewFinder Optic GS180; Light & Motion Tetra 5060 (return to machined aluminum); Sea & Sea YS-55TTL/E E-TTL strobe and Nikon D70/Digital Rebel housings; NightSea UV/fluorescence filter system; DivePhotoGuide.com appeared as a media exhibitor. The convention center floor was “almost deserted” due to the location, but business was reportedly good due to easier one-on-one meetings. Ike Brigham of Ikelite called the coverage “absolutely spectacular.” ([12], [13], [14])

DEMA 2005 (October, Las Vegas, NV)

HD video was the dominant theme. Christa Loustalot covered the show for Wetpixel (Cheng was diving in Galapagos, Wiseman had work). Drew Wong produced a dedicated Sony HDV camera housing roundup covering every manufacturer’s approach to housing the Sony HDR-HC1 and FX/Z1 cameras: Sea & Sea, Amphibico, Light & Motion, and Gates. Film was “nonexistent” except for Snapsights’ disposable cameras. Wetpixel received the Scuba Diving Magazine Editor’s Choice Award for “Best Dive-Related Website” — the magazine’s first-ever Editor’s Choice Awards — presented on stage at DEMA and accepted by Loustalot on behalf of Wetpixel. The first Wetpixel Happy Hour was held at the show. ([15], [16], [17])

DEMA 2006 (November 8-11, Orlando, FL)

The most exhaustively covered DEMA in Wetpixel’s history: 44 individual booth articles published in real-time over three days. Eric Cheng and Drew Wong reported for Wetpixel, with Wong producing a separate video products roundup. Coverage spanned every major imaging exhibitor: Seacam, Light & Motion, Backscatter, Ikelite, Sea & Sea, Subal, Inon, Nexus/Marine Camera Distributors, Gates, Aquatica, Patima, Keldan, NiteRider, SeaLife, Fantasea, Bonica, Amphibico, AquaVideo, NCUPS, Nocturnal Lights, 10bar, Fisheye/Seatool, and the Art Innovation Center. The first Wetpixel/DivePhotoGuide cocktail party was held. DivePhotoGuide, X-Ray Magazine, Fathoms Magazine, and other media covered the show alongside Wetpixel. ([18], [19])

DEMA 2007 (October 31 - November 3, Orlando, FL)

32 articles of coverage by Cheng, Wong, and Matt Segal. Key exhibitors included Aquatica, Gates (Stan Waterman event), Ikelite, Inon America, Subal, Light & Motion, Olympus America, Backscatter, Seacam USA, Nexus USA, Sea & Sea, Amphibico, Fantasea, Keldan, Fisheye/Seatool, Epoque, 10bar, Bonica, NiteRider, Princeton Tec, and many more. DEMA’s “Be a Diver” national advertising campaign was presented. The Wetpixel Happy Hour was held. ([20], [21])

DEMA 2008 (October, Las Vegas, NV)

37 articles of booth-by-booth coverage. The historic debut of Nauticam, described by Cheng as “a total newcomer to the industry,” showing their patent-pending WB-PORT white balance dome port accessory — a translucent white iris that could be opened and closed to provide average light values for white balancing. Edward Lai, Nauticam’s founder, engaged in the comment threads defending the product and discussing its design evolution. The WB-PORT marked Nauticam’s entry into the market before they began producing camera housings. Other major exhibitors: Ikelite, Sea & Sea, Gates, Seacam, Subal, Aquatica, Inon, Backscatter, Light & Motion, Olympus, Fisheye/Seatool, Patima, Fantasea, Keldan, and Oceana/Sea Shepherd (conservation organizations). The Wetpixel/DivePhotoGuide cocktail party was held, preceded by a dinner at Scarlett restaurant. ([22], [23], [24])

DEMA 2009 (November, Orlando, FL)

Multi-day coverage by Eric Cheng, Matt Segal, Shawn Heinrichs, Norbert Wu, and Richard Remski. Michaela Brockstedt and Adam Lau staffed the Wetpixel booth (#1068) representing Wetpixel Quarterly. Cheng used Twitter for real-time updates from the show floor for the first time. The Wetpixel/DivePhotoGuide cocktail night was held. This was Cheng’s final DEMA as Wetpixel’s primary correspondent. ([25], [26], [27])

DEMA 2010 (November 17-20, Las Vegas, NV)

The first DEMA covered by Adam Hanlon and Sterling Zumbrunn for Wetpixel, with Norbert Wu also reporting. Wetpixel booth #1344. Multi-page coverage spanning seven days of content. Key products: ReefNet fiber optic snoot for Ikelite strobes; ULCS tripod and GoPro Hero mount prototype; Watershot LED lighting systems; Equinox housing range including plans for a Panasonic SD750 3D camera housing; Subal full line including Nikon D300s and Canon 7D housings with new port locking mechanism, 9-inch anti-reflective glass dome ($1,900), and prototype Sony NEX-5 housing. The Wetpixel/DivePhotoGuide cocktail party was held Thursday November 18. A notable controversy emerged when the Las Vegas Hilton, where most dive industry attendees were staying, was found serving shark fin soup. A protest led by dive industry attendees resulted in the hotel agreeing to remove shark fin products from its menu — a conservation victory documented by Sharksavers. ([28], [29], [30])

DEMA 2011 (November 2-5, Orlando, FL)

Adam Hanlon provided comprehensive booth coverage over five days plus pre-show setup. Shawn Heinrichs received the Sea Hero of the Year Award at the show. The Wetpixel/DivePhotoGuide pool party was held. Hanlon reflected that DEMA is “as much about people, conversations and ideas as it is about equipment.” ([31], [32], [33])

DEMA 2012 (November, Las Vegas, NV)

Dave Burroughs covered the show for Wetpixel — his first DEMA visit. Nauticam showcased housings for the Sony RX100, Panasonic LX7, and Canon S110 compacts. Ryan Canon of Nauticam recommended the Sony RX100 as the best compact for wide-angle underwater and the LX7 as the best for macro. Ikelite debuted the Vega LED video/still focus light (2000 lumens, heat-radiating design) and the Manta optic fiber strobe (pre-flash recognition technology). Ikelite also showed new lithium battery packs for DS-series strobes making them neutrally buoyant. Louis Prezelin demonstrated Light & Motion’s Sola Nightsea UV fluorescence system. Acquapazza showed a prototype Sony RX100 housing. The Wetpixel/DivePhotoGuide party was held. ([34], [35])

DEMA 2013 (November, Orlando, FL)

Adam Hanlon and Abi Smigel Mullens covered the show. Hanlon wrote the preview article “whilst jetting my way across the Atlantic on a 747, watching Doug Sloss’s ‘Lightroom for Underwater Photographers.’” The Wetpixel/DivePhotoGuide party was held poolside at the Rosen Center. ([36], [37], [38])

DEMA 2014 (November 19-22, Las Vegas, NV)

Comprehensive seven-page coverage by Adam Hanlon, with contributions from Mark Goyen and Steve Williams. 4K video dominance as the show’s defining technology trend. Mirrorless cameras surged as a category with multiple manufacturers showing dedicated housings. Fluorescence photography emerged as a significant new technique, with Ikelite launching a full line of fluorescence accessories (exciter filters for DS strobes, yellow lens port filters, mask filters). Key products: Backscatter Flip 3.1 filter system for GoPro HERO4 with Macromate Mini close-up lens ($89); GoPro HERO4 Black (4K at 30fps) and Silver with Protune manual controls; Keldan Video 4X (6,000 lumen) and 8X (10,000 lumen) lights with dome lenses; Subal “Angler” Nikon D4s housing designed for deep diving (130-140m), D810 housing, and OMD-EM1 housing with innovative on/off switch; Ikelite MIL (Mirrorless Interchangeable Lens) housing range, Blackmagic Pocket Cinema Camera housing, redesigned arm system; Nauticam and Aquatica exhibits; Subal Spell Shell housing for Blackmagic Pocket Cinema Camera. Presenter Joel Penner spoke at the IRC. ([39], [40], [41])

Adam Hanlon and Abi Smigel Mullens produced five pages of coverage. ULCS showed Terry Schuller and Dave Reid at their approximately 23rd DEMA show. Key products: Nauticam Wet Wide Lens WWL-1 (“breakthrough” optic offering 130-degree FOV with full zoom-through for compacts and mirrorless), CMC super macro conversion lens, and housings for Sony a7II/a7RII/a7SII, RED Weapon, Arri Alexa Mini, and multiple compacts; Aquatica Sony a7R II housing with electro-optical converter; Subal Sony a7R II and FS-7 housings; GoPro HERO4 Session; XIT404 tripod updates; i-Torch Symbiosis SS-2 combined strobe/video light. Bernie Campoli was seen extolling the virtues of converted Nikonos RS lenses. The Wetpixel/DivePhotoGuide imaging party was held. ([42], [43])

Six pages of booth visits covering Seacam, Aquatica, ULCS, Nauticam, XIT404, SAGA, Vivid Pix, Light & Motion, Subal, Ikelite, CineBags, Isotta, Acquapazza, iDivesite, Backscatter, Gates, BS Kinetics, Fantasea, Fisheye, Keldan, Sea & Sea, and Inon. Cristian Dimitrius presented talks at the IRC. Wetpixel began posting to their “Wetpixelgram” Instagram feed during the show. The Wetpixel/DivePhotoGuide party was held. ([44], [45])

DEMA 2017 (November 1-4, Orlando, FL)

Drew Wohl, Lureen Ferretti, and Adam Hanlon covered the show across five pages. Major product launches included the Nauticam Wide Angle Corrector Port (WACP) — a water-contact converter port that optically corrects lenses underwater, offering 130-degree FOV at 28mm with full zoom-through capability at a retail price of $3,250; Gates Pro Explore cinema housing for RED DSMC2 8K cameras; Keldan lighting updates with increased outputs across the line (Luna 4X now 9,000 lumens, 8X at 15,000, 18X at 25,000, 24X at 30,000) and new Spectrum gel dichroic color correction filters; Nauticam housings for Nikon D850/D7500, Sony a9, Panasonic GH5, Canon C200, and converted Nikonos RS lenses; ULCS new handle designs with 1/4-inch threads; Acquapazza prototypes for Sony a9 and deep-rated (200m) Sony a7 II housing with 170mm dome port. Ryan Canon and Edward Lai of Nauticam presented the WACP in detail, noting compatibility with 150 different lenses under evaluation. The Wetpixel/DPG party was held. ([46], [47])

DEMA 2018 (November, Las Vegas, NV)

Abi Smigel Mullens covered the show in a “more relaxed” style than previous years, focusing on the social atmosphere and key highlights rather than exhaustive booth-by-booth coverage. Women Divers Hall of Fame held their Flippers and Flappers party with new inductees. Industry figures present included Douglas Seifert, Burt Jones, Maurine Shimlock, Keri Wilk, Vladimir Mladenovic (Subal), Andy Bausk (Olympus), Jordi Benitez (SAGA), and Tanya Burnett. ([48])

DEMA 2019 (November, Orlando, FL)

Adam Hanlon reported extensively across four pages. Marquee product launches included:

Seacam also showed completed converted Nikonos RS 28mm lenses and announced housings for Sony a7rIII/a9 and a7rIV/a9II. The Wetpixel/DPG party was held.

DEMA 2020 (Canceled - COVID-19)

The 2020 show was canceled due to the COVID-19 pandemic. Adam Hanlon and Alex Mustard hosted a “Wetpixel Live” video episode predicting what would have been shown, discussing products that had made their way to market without a DEMA debut. ([52])

DEMA 2021 (November, Las Vegas, NV — not covered in person)

DEMA 2021 was not covered by Wetpixel in person. Instead, the Wetpixel Virtual Trade Show ran via Wetpixel Live (Eps 214-221), with 8 manufacturer showcase episodes: SAGA, Easydive, Inon, Scubalamp, Nauticam (three episodes), and Backscatter. ([53], [54])

DEMA 2022 (November, Orlando, FL)

Coverage by Tom St. George via video. Exhibitors documented included Marelux, Backscatter, Nauticam, Shearwater, Aggressor Fleet, Fourth Element, and Seacraft. Hanlon was unable to attend (“I was sadly unable to attend the annual DEMA Show this year”). Wetpixel Live produced 7 extra DEMA 2022 episodes featuring Aggressor, Backscatter, Fourth Element, Marelux, Nauticam WACP-C, Seacraft, and Shearwater. ([55], [56])

The Film-to-Digital Transition (2000-2005)

DEMA’s imaging section documented the entire arc of the digital underwater photography revolution:

The HD/4K Video Revolution (2005-2014)

Following HD video’s dominance at DEMA 2005, video became an increasingly important part of each show, culminating in 4K as the defining trend at DEMA 2014. Cinema housings for RED cameras, Blackmagic cameras, and Sony FS-series appeared alongside traditional photography housings.

The Mirrorless Camera Era (2010-Present)

Starting with Subal’s prototype Sony NEX-5 housing at DEMA 2010, mirrorless cameras steadily grew in DEMA representation. By 2015, Nauticam’s WWL-1 wet wide lens was designed specifically to exploit mirrorless camera advantages, and by 2019, major manufacturers were releasing more mirrorless housings than DSLR ones.
