The Canon 7D, when paired with the Aquatica A7D housing, presents an impressive option for underwater photographers seeking high performance and reliability. With several dives completed using this combination, the results leave little to be desired. Upgrading from a Canon 40D/50D setup, the differences were immediate and noteworthy. The improved viewfinder clarity with the optional AquaView, combined with blazing-fast autofocus underwater, instantly elevated the shooting experience. The precision fit of the camera into the Aquatica housing makes for a seamless assembly. A minor drawback, however, was the lack of a pre-installed moisture alarm, which would have been a thoughtful inclusion out of the box.
Housing Design and Technical Specifications
The Aquatica A7D housing is expertly crafted from a single block of aluminum, reflecting durability and design integrity. It’s rated for depths up to 90 meters, with an optional upgrade to 130 meters for those venturing into deeper waters. This robust design includes both optical and sync cord bulkheads, a bayonet mount, and offers the ability to change ports or lenses without removing the camera—an efficient and user-friendly feature. Optional upgrades such as a hydrophone and AquaView viewfinder further enhance customization for professional use.
Underwater Still Photography Performance
When tested in underwater still photography, the Aquatica A7D housing proved itself compact and lightweight compared to previous models. Utilizing existing lenses, strobes, and ports, the transition was smooth. Key controls such as aperture, shutter speed, and shutter release are intuitively placed. The dials are also easier to operate thanks to bolder edges that provide better grip, even when wearing gloves in temperate waters. Buttons operate smoothly despite having deep springs, and the ergonomically angled bank of buttons on the housing’s rear left is a welcome improvement. True to Aquatica’s tradition, the hand grips offer exceptional comfort and handling, enhancing stability during dives.
Display and LCD Visibility
The LCD screen on the Canon 7D is showcased effectively within the housing. One of the common complaints with older models, such as the 50D, was that the top of the screen could be obscured, especially when using the AquaView. With the A7D housing, that issue has been resolved. The LCD window is thoughtfully positioned to ensure optimal visibility, even with the AquaView in place. While the housing omits the top LCD window, the Canon 7D’s information screen more than compensates, making the top display largely unnecessary.
Housing Buoyancy and Handling
Exact buoyancy data isn’t provided, but field use reveals helpful insights. With an 8-inch dome port, 28mm lens, dual DS-125 strobes, 6-inch Stix arms, and 10-ounce floats, the rig maintains a nearly neutral buoyancy. There is a slight upward rotation caused by the dome’s buoyancy. Swapping to a flat port makes the rig more negatively buoyant and minimizes this rotation. The overall setup feels balanced and manageable underwater, particularly with the addition of Stix floatation aids.
Video Recording Capabilities Underwater
Entering underwater videography with limited experience, the reviewer conducted several dives, shooting both macro and wide-angle footage with the Canon 7D. While initial attempts with a 60mm lens proved challenging due to focus issues, switching to a 28mm f/1.8 lens produced more usable results. An early misstep involved remapping the AF-ON button for still shooting, which inadvertently disabled autofocus while recording video. This issue was later resolved by using the custom C1 mode to create a separate configuration for video use.
Despite turbulent conditions, the Canon 7D demonstrated promising video capabilities. The ability to pre-lock focus before recording is especially valuable for wide-angle shots. Concerns about low-light performance at depth were addressed satisfactorily, with ISO 800 footage retaining decent quality. The reviewer noted some frustration with the placement of the Start/Stop button, which is difficult to reach without releasing the grip, especially problematic during macro or focused video work. Attempts to use AF-Live for refocusing during video recording were unsuccessful, as it disrupted focus and exposure, rendering footage unusable.
Limitations and Observations
Lighting posed another challenge during video shooting. The reviewer was using a Fisheye HG20DX light, which lacked the power needed for smaller apertures. Consequently, shooting with wider apertures (f/2.8–f/11) was necessary, though this approach came with a trade-off in depth of field control. The built-in microphone on the Canon 7D performs well enough to capture ambient audio, such as breathing sounds, which may or may not be desirable depending on post-production plans. The reviewer chose not to invest in the hydrophone, reasoning that most quality underwater footage is paired with music in post-processing.
Performance Above Water and Maintenance
Mounting the Canon 7D into the A7D housing is straightforward. However, unlike previous Aquatica models, memory card access is not possible without removing the camera. Despite this, the ease of removing the camera—even with the lens and zoom collar still attached—makes it a minor inconvenience. A key feature is the housing’s port lock mechanism, though it locks only a single port or collar at a time. This limitation becomes apparent when using multiple bayonet-style attachments.
Improvements in button recesses are also evident. Small holes in the side of each button shaft allow water to flush through more effectively during cleaning, reducing salt buildup significantly compared to previous designs. The rugged, matte black finish feels durable and capable of withstanding harsh underwater environments. Installing the AquaView on this model is also easier thanks to a beveled housing hole, which guides the o-ring into place more smoothly, reducing the risk of pinching during installation.
Structural Enhancements and Flood Prevention
One of the most significant improvements lies in the bulkhead o-ring groove. The design is smoother than in previous housings, especially the older 50D version. A smoother groove ensures a better o-ring seal, thereby reducing the chance of flooding—a top concern for any underwater photographer. The tighter fit and improved ergonomics of the Aquatica A7D suggest careful attention to detail in engineering.
Strobe Compatibility and Flexibility
Aquatica provides multiple strobe connectivity options, including Nikonos, Ikelite, and optical fiber ports compatible with Inon and Sea & Sea strobes. The reviewer chose a hybrid setup: one Ikelite bulkhead and one optical fiber. This flexibility allows the use of current DS-125 strobes with a Y-splitter cable and supports future upgrades to more compact Inon z240 units. The system permits TTL functionality and manual control, which, while not critical for the reviewer, adds an extra layer of versatility to the rig.
Summary of Findings
The Canon 7D, supported by Aquatica’s well-engineered A7D housing, emerges as a formidable combination for underwater photography and video. Capable of handling extreme depths and harsh environments, it meets the technical demands of serious divers and visual storytellers. The Canon 7D’s rapid autofocus, excellent LCD, and overall image quality make it a standout, while the Aquatica housing provides intuitive control, secure construction, and thoughtful design improvements over previous models.
Daily Handling and Field Setup Efficiency
Preparation before a dive is often just as important as the dive itself. A housing like the Aquatica A7D must be intuitive and cooperative during setup. In field conditions, divers often work from boats, piers, or confined spaces where gear has to be handled quickly and efficiently. With this in mind, the Aquatica housing performs admirably. Mounting the Canon 7D into the housing is a simple, non-frustrating process. Unlike some housings that require delicate maneuvering or feel overly tight, the A7D accepts the camera body with a confident click and fits perfectly with no signs of looseness or unnecessary resistance.
Changing ports and adjusting lens settings is also straightforward, and divers can easily prepare multiple configurations—macro, wide-angle, and mid-range lenses—depending on the dive site and conditions. The port system’s bayonet mount is quick to use, and even with cold or gloved hands, locking and unlocking ports is smooth. The absence of a complicated multi-step locking process makes setup faster and more reliable when time is of the essence.
Comfort in Cold Water Environments
For those diving in cold or temperate waters, hand dexterity becomes a concern. Gloves reduce tactile sensation, making it harder to press small buttons or turn tight dials. However, the Aquatica A7D’s controls have been designed with cold water diving in mind. The buttons are spring-loaded but with a generous amount of resistance, allowing divers to operate them even with thick gloves. This isn’t just a small convenience—it is an essential design requirement that directly impacts performance under real-world conditions.
The larger dials feature raised grips and ridges, which make them easier to turn without slippage. Aperture and shutter speed controls are especially accessible. In comparison to the Canon 50D’s housing, which featured flatter dials and smaller grips, the Aquatica A7D is a significant improvement.
Buoyancy in Varied Dive Conditions
The rig’s balance underwater depends on many variables, including dome or flat ports, strobe positioning, and floatation accessories. The default configuration with an 8-inch dome, a 28mm lens, and dual DS-125 strobes renders the setup neutrally buoyant with minimal front tilt. In this configuration, rotation toward the dome side is present, but it is manageable and predictable.
Adding Stix arms and 10-ounce floats significantly reduces fatigue during long dives. Without floatation aids, the housing would be front-heavy and could require more muscle to control, especially on longer dives or during complex compositions. Switching to a flat port reduces this dome-induced tilt and results in slightly negative buoyancy overall. These behaviors are easily adjusted with simple changes in accessories or weight distribution. The housing’s natural neutrality is ideal for most divers and gives users the flexibility to fine-tune balance based on their preference and lens selection.
Stability and Trim in Underwater Photography
One of the unsung heroes of underwater photography is rig stability. A camera housing must not only be easy to carry but also respond accurately to minor changes in angle or direction. The Aquatica A7D housing provides superb stability thanks to its ergonomic design and even weight distribution. When taking a shot, particularly macro, holding focus and keeping the camera motionless is essential. This housing allows the user to maintain steady trim with minimal wrist movement.
Macro photography with a 60mm lens requires precise positioning, and any minor movement can throw focus off completely. The Aquatica grips help brace the housing against chest or hand pressure, reducing movement from breathing or surge. Similarly, wide-angle shots benefit from the housing’s resistance to sudden shifts, allowing the photographer to frame and lock focus more reliably.
Port and Lens Compatibility
Lens compatibility is crucial for a housing system. Photographers working across different disciplines—wreck diving, reef exploration, macro nudibranch shots—must be able to switch configurations easily. Aquatica supports a wide range of lenses with port adapters that make transitions smooth. From the Tokina 10–17mm fisheye to the Canon EF-S 60mm macro and 100mm L macro lenses, the housing accepts all with ease when matched with the proper port and gear.
The zoom and focus gears fit snugly and turn accurately. When shooting video, manual focus with a properly geared lens becomes not only possible but reliable. Aquatica’s internal space leaves room for collars without requiring removal of ports during gear changes, saving time and reducing the risk of flooding.
Camera Settings Access and Custom Controls
One of the Aquatica housing’s biggest strengths lies in how easily it provides access to nearly all of the Canon 7D’s buttons and settings. ISO, white balance, drive mode, and autofocus adjustments are all accessible via clearly labeled buttons that align perfectly with the camera body inside. Users do not have to guess or press multiple buttons in frustration. Each button provides satisfying tactile feedback and allows quick navigation through menus and modes.
Many underwater photographers use custom settings heavily. With the Canon 7D, the C1–C3 custom settings on the dial can be programmed to save specific shooting modes, white balance profiles, and autofocus configurations. Aquatica’s housing allows users to switch between these without opening the housing or fidgeting with controls. In practice, switching from a macro video mode (C1) to a still photo wide-angle setup (Manual mode) underwater becomes a matter of turning a single dial.
Field Observations on Exposure Management
Light is perhaps the most inconsistent variable underwater. Refraction, scattering, turbidity, and depth all play a role in exposure. The Canon 7D handles ISO and white balance admirably, and Aquatica’s controls allow quick changes on the fly. On one dive, switching from f/4 at ISO 400 to f/8 at ISO 800 with one dial and two buttons took seconds and saved an otherwise underexposed shot. This speed of adjustment is critical in fast-moving scenes or when shooting pelagics.
The control wheels are comfortably spaced and precise. Exposure compensation and custom function buttons are also accessible. The ergonomic button placement removes the need to reposition your hand entirely, which avoids disturbing trim or scaring away subjects during critical moments.
Observations on Moisture Control and Internal Design
Moisture alarms are a valuable safeguard, but Aquatica has chosen not to install them by default. This means users need to install the alarm unit themselves. Although a minor inconvenience, installing the alarm is not overly complicated. Once installed, it provides reliable alerts in the unlikely event of water intrusion.
Internally, the housing is intelligently laid out. The camera aligns flush against internal guides, and o-rings sit in machined grooves that are clean and easy to inspect. Button shafts allow water to flush out during rinsing, preventing the buildup of salt deposits and ensuring long-term reliability. The smoother grooves, especially around the main rear door o-ring, reduce the chance of pinching and improve sealing quality.
Reliability in Harsh Environments
Aquatica’s black anodized finish resists scratches and corrosion. Divers who frequent wrecks, caves, or low-visibility environments where bumping against rocks or debris is common will appreciate the tough exterior. Even after multiple dives and exposure to saltwater and sand, the housing holds up well. Threads, controls, and mounts all maintain their mechanical feel and don’t degrade in quality with repeated use.
The AquaView finder, which many users install for better framing, fits securely and avoids o-ring pinching thanks to the beveled rear opening. This design upgrade prevents tearing, which can lead to leaks. The fit and finish of these components reflect thoughtful engineering that goes beyond simple compatibility.
Performance in Deep Dives and Low Light
Divers operating below recreational limits—particularly tech divers or deep wreck enthusiasts—will find the A7D’s depth rating critical. While many housings stop at 60 meters, Aquatica's standard build handles 90 meters and can be upgraded to 130 meters. In deep ambient-light-limited situations, high ISO performance becomes essential. The Canon 7D delivers clean video at ISO 800, and the housing enables full control without compromise. Users can keep their camera locked at ISO 800–1600 and rely on strobe exposure or lighting to balance their frame.
Focus peaking, zebra striping, or histogram monitoring may not be native to the 7D, but with the Aquatica viewfinder and screen placement, users can quickly analyze the LCD to ensure good exposure even in dark waters. This flexibility makes the housing and camera combo suitable for challenging lighting situations and deeper technical dives.
Transitioning Between Photography and Videography
One of the most exciting aspects of the Canon 7D is its hybrid nature. With a simple flip of a switch and a press of a button, users can transition from stills to full HD video. The Aquatica housing allows this transition with little interruption. Custom buttons can be used to remap Start/Stop, autofocus, and metering controls to suit a user’s preference. Although the Start/Stop button location requires disengaging the grip to reach, the tradeoff is a cleaner, uncluttered grip and fewer accidental presses.
For those who prioritize video, a custom setup can reduce this inconvenience. In addition, the lens choice and lighting plan affect usability significantly. A wider lens, such as the Tokina 10–17mm or Canon 10–22 mm, is better suited to dynamic videography, while a fixed prime like the Canon 28mm f/1.8 offers a good middle ground with brighter aperture and improved.

Real-World Dive Testing and Performance Underwater
The true capability of any underwater housing is best measured not in specifications but in the real environment it was built for. During multiple dives across various environments—wrecks, reefs, low-light caverns, and moderate currents—the Aquatica housing for the Canon 7D proved to be reliable, responsive, and confidence-inspiring. The camera remained fully functional with immediate response to control input, and the housing showed no signs of resistance or flooding throughout.
Divers using the Canon 7D in Aquatica’s A7D housing can expect consistent control responsiveness at different depths and under varying temperature conditions. The housing’s control feedback did not degrade after long exposure to cold or deep environments, and there was no loss of spring tension or button misalignment. This means the user can shoot without worrying about housing behavior affecting critical timing or capture opportunities.
Macro Photography in Limited Visibility Conditions
Macro photography underwater comes with its unique challenges. Subjects are often small, well-camouflaged, and surrounded by terrain or organisms that can easily confuse autofocus or reflect strobes poorly. In such scenarios, the Canon 7D’s fast and reliable autofocus engine, combined with Aquatica’s intuitive housing control, allowed the reviewer to capture detailed shots of nudibranchs, crustaceans, and stationary fish species at close range.
The housing’s button placement, especially for back-button focus and shutter control, allowed focus locking without unnecessary camera movement. Using a Canon EF-S 60mm lens in a flat port configuration, the sharpness and clarity achieved were impressive. Manual focus adjustments through the focus gear worked well, and fine-tuning in Live View mode was possible, albeit slow. Autofocus was typically fast and accurate in macro distances, provided ambient light or torch light was sufficient.
A small but appreciated detail was the housing’s grip texture and balance, which allowed it to rest stably on rocks or sandy bottoms without tipping. When working slowly across a reef, maintaining stability for several seconds at a time was crucial for getting a sharp macro shot. The housing enabled this with minimal effort.
Wide-Angle Shooting and Subject Framing in Open Water
Wide-angle photography, especially when shooting large subjects like shipwrecks, stingrays, or reefscapes, benefits from responsive controls and a balanced housing. The Aquatica A7D excels here. Paired with a Tokina 10–17mm fisheye or Canon 10–22mm lens, and using an 8-inch dome port, the results were both sharp and immersive. Edge-to-edge sharpness was consistent when the dome was properly aligned, and corner softness—often a problem with lower-end dome systems—was well controlled.
In open water, often with limited reference points, fast-changing light, and mobile subjects, the photographer must compose quickly. The Canon 7D’s optical viewfinder through the AquaView finder presented a clear and bright scene even when the subject was moving rapidly. The housing’s controls, especially the exposure dials and focus lock buttons, were placed in a way that allowed users to keep both hands on the grips while adjusting for exposure compensation or shutter speed. This layout enabled accurate real-time exposure control without disturbing framing.
Large marine life, including turtles and pelagic fish, could be tracked effectively. The 7D’s autofocus tracking, assisted by the housing’s responsive button system, made tracking easier than previous Canon models. Focus performance remained consistent in ambient light down to around 25 meters, and with strobe support, deeper shooting remained practical without major loss in focus speed.
Underwater Lighting and Strobe Integration
Lighting is fundamental to underwater photography. Poor lighting can make even the best composition unusable. The Aquatica housing supports multiple strobe configurations, including optical fiber and electrical sync cord connections. In practice, the reviewer used a dual-strobe setup—Ikelite DS-125s in one test and Inon Z-240s in another—to test exposure consistency, recycle time, and lighting balance.
Optical triggering performed as expected with minimal lag. The fiber optic cables were easily secured and did not detach during dives, even in currents. Manual strobe control was preferred over TTL due to the Canon 7D’s somewhat limited TTL reliability underwater, though TTL did perform well in balanced light scenes such as shallow coral reef dives.
Strobe arm positioning was made easier by the housing’s reinforced handles. These allowed for strong support points and predictable positioning when adjusting lighting angles. Backscatter was minimized by proper strobe distancing, and the dome port did not suffer from flaring or unwanted reflections. The reviewer reported success in obtaining soft, even lighting on wide-angle reef scenes with visible blue water in the background.
For macro, smaller strobes like the Inon Z-240s delivered consistent flash coverage and worked well in tight spaces. The housing supported this configuration easily, and the camera’s flash sync worked reliably across all tested depths.
Autofocus Behavior with Fast-Moving Subjects
Tracking moving subjects underwater, such as schooling fish or approaching marine mammals, requires both speed and accuracy. The Canon 7D’s autofocus system, when housed in the Aquatica A7D, responded quickly and reliably to both stationary and mobile targets. Using AI Servo mode, the autofocus followed subjects accurately with minimal hunting, even in low-contrast settings such as shaded overhangs or cave entries.
Button placement allowed easy AF point switching without needing to navigate complex menu paths. In practice, the most efficient technique was to pre-set the autofocus point before the dive or before approaching the subject, locking focus when the subject was in range. This ensured higher success in dynamic shooting situations.
In fast-paced dives where subjects like sharks or rays only offer a few seconds for the shot, the ability to lift the camera, lock focus, adjust exposure, and shoot within moments proved invaluable. The camera and housing combination responded intuitively, giving the diver confidence in their equipment.
Manual Focus and Creative Techniques
While autofocus remains dominant for most use cases, underwater photographers occasionally require precise manual control. This is particularly true in creative focus techniques or subjects with limited contrast. The Aquatica housing’s compatibility with focus gears made manual focus viable and precise.
Using focus peaking was not possible on the Canon 7D without external monitors, but focus confirmation via Live View and subtle lens adjustments worked well for macro setups. Manual focus rings operated smoothly, and the housing allowed sufficient torque transfer from external dials to the lens without lag or stiffness.
Creative shots such as focus pulls between coral and background fish, or soft-background bokeh compositions using wider apertures, were successfully captured during test dives. The Canon 28mm f/1.8 was especially useful here, giving shallow depth of field and clean background separation.
Dealing with Environmental Challenges
Underwater environments pose many variables. Silt, currents, surge, and thermoclines can create visual disturbances or interfere with focus and exposure. The Aquatica housing helped mitigate these with its solid trim and dependable sealing.
In silty environments, the housing’s hydrodynamic shape prevented particles from stirring up as the diver approached subjects. The lens port seals remained clear despite murky water, and internal fogging was not encountered, thanks to effective o-ring compression and good use of desiccants.
During surge dives, particularly in reef crevices or coastal caves, the housing’s ergonomic handles allowed the diver to brace against rocks or ledges without losing grip. The camera body did not rattle or shift within the housing, preserving alignment and allowing steady shooting even with sudden movement.
Post-Dive Gear Care and Maintenance
Proper care after diving is essential to maintaining any housing. The Aquatica housing made post-dive cleaning efficient. The matte exterior held up well against saltwater exposure and minor scrapes. The control buttons allowed freshwater to flush through their side ports, minimizing salt deposits and making rinsing more effective.
After rinsing, all controls were moved several times to ensure no salt or sand remained lodged. The main o-ring was easy to inspect due to the housing’s smooth sealing surface and was not prone to pinching or dust buildup. Removing the camera was simple and did not require disassembling the port or strobe cables.
Over time, corrosion did not appear on screw threads or mounting points, which suggests Aquatica’s anodizing process is robust. The reviewer did not report any issues with paint flaking, rust, or leaking, even after extended field use.
Shooting Scenarios and Subject Handling
Each type of subject requires a different approach. Small crustaceans demand proximity, stillness, and lighting control. Mid-size reef fish call for quick framing and strobe adjustment. Large animals and wrecks depend on dynamic composition and wide lenses.
The Aquatica housing met the demands of all three. In nudibranch shoots, where movement must be minimized, the flat port and macro lens combination remained steady and easy to operate. In fish school environments, fast subject movement was matched by fast shutter control and well-placed zoom rings. In wrecks or caves, where light is scarce and angles are tight, the dome port provided coverage without needing multiple takes.
The versatility of the housing meant that the photographer never had to compromise the shot because of the gear. Whether focusing on eye detail in a macro subject or capturing entire wreck silhouettes in low light, the Canon 7D and Aquatica housing held up under pressure.
Creative Flexibility and Final Shot Output
Once footage and photos were downloaded and reviewed, the results confirmed what was felt during the dives. Still images displayed high sharpness, accurate color, and minimal distortion. The housing’s optical alignment allowed full use of the lens’s capabilities. Wide-angle distortion was minimal and easily corrected in post-production.
Video clips, once the Start/Stop configuration was properly optimized, showed clear detail, smooth exposure transitions, and low noise levels up to ISO 800. Strobe-lit footage showed rich contrast and accurate color, with no lens flare or backscatter in most controlled shots.
Aquatica’s design allowed the photographer to capture the full range of creative ideas with minimal technical limitations. The gear did not get in the way—it enabled better, faster, more thoughtful photography.
Advanced Underwater Photography with the Aquatica Housing for Canon 7D
Aquatica has earned a reputable position in the underwater imaging world by providing reliable, robust, and innovative camera housings for professionals and enthusiasts alike. When paired with the Canon 7D—a DSLR known for its speed, image quality, and versatile shooting capabilities—this housing system becomes a powerful tool for underwater storytelling.
Ergonomics and Button Accessibility Underwater
In any underwater housing, one of the key design challenges is replicating the tactile experience of handling a camera in open air. Aquatica tackles this through an exceptionally well-designed control layout that mirrors the Canon 7D’s native controls. The placement and response of each button, dial, and lever are engineered for usability in cold water or while wearing gloves.
Users can seamlessly access all essential camera functions—ISO, shutter speed, aperture, white balance, and autofocus points—without having to remove their eyes from the viewfinder. Dials are knurled for grip, while levers are spring-loaded for intuitive operation. The multi-controller is also accessible for menu navigation, making it easier to switch modes or fine-tune settings mid-dive.
Photographers using the 7D’s back-button autofocus will appreciate the prominent and easy-to-reach AF-ON button, which is replicated accurately on the housing. This becomes especially vital when tracking fast-moving subjects like reef fish or marine mammals.
Compatibility with Lenses and Ports
Aquatica designed its housing for the Canon 7D to support a wide array of lenses, acknowledging that underwater photographers use different focal lengths for macro, portrait, and wide-angle shots. The housing accepts Aquatica’s modular port system, which includes flat ports for macro lenses and dome ports for wide-angle and fisheye glass.
Popular lens pairings include:
-
Canon EF 100mm f/2.8L Macro IS USM for close-up shots of nudibranchs and shrimps
-
Tokina 10–17mm f/3.5–4.5 fisheye for expansive reefscapes and over-under shots
-
Canon 17–40mm f/4L or EF-S 10–22mm for wide-angle storytelling
The port locking system on the Aquatica housing ensures a secure seal, with no risk of accidental unlocking mid-dive. The gear-driven focus and zoom controls are housed in robust aluminum knobs, offering smooth operation even in strong currents.
Strobe Connectivity and Lighting Control
Lighting is the heartbeat of underwater photography. Without natural light below 10 meters, strobes or continuous lights become critical. The Aquatica housing for the Canon 7D offers multiple options for strobe connection, supporting both fiber optic and electronic sync cables.
The housing includes dual optical connectors for fiber-optic sync and also allows for the addition of Nikonos-style bulkhead connectors for electronic triggering. Photographers can choose between TTL and manual strobe modes depending on the external flash system used.
Many Canon 7D shooters pair this housing with powerful strobes like the Sea & Sea YS-D3, Inon Z-330, or Ikelite DS-160. These setups allow creative lighting effects, including backlighting, snoot lighting, and fill flash in shadowy areas. The ability to adjust strobe power directly from the housing enhances creative control, especially during fast-paced shooting sessions.
Buoyancy and Trim Balance
A common concern with DSLR housings is their tendency to be front-heavy, especially when dome ports and twin strobes are mounted. Aquatica addresses this through careful housing design and optional accessories. The standard Aquatica 7D housing has a slightly negative buoyancy when used with a dome port and strobes, providing stability during hovering shots.
For fine-tuning buoyancy, users can add floating arms or attach trim weights to achieve neutral buoyancy and better trim underwater. This is essential for macro photography, where even small movements can throw off focus.
The anodized aluminum construction contributes to both strength and balance. The weight underwater is manageable even during long dives, and the housing remains comfortable when handheld or mounted on a tripod.
Maintenance, Travel, and Long-Term Durability
Durability is where the Aquatica brand truly shines. The aluminum shell is corrosion-resistant and can withstand the wear and tear of saltwater exposure, transport, and temperature changes. O-ring sealing is extremely reliable, with dual main seals that protect the camera chamber and port interface.
The housing includes a vacuum leak detection system to ensure a watertight seal before entering the water. By drawing a vacuum and monitoring the pressure inside the housing, photographers can detect any issues before submersion. This system gives peace of mind, especially on expensive dive trips.
Cleaning and maintenance are straightforward:
-
Rinse the housing in fresh water after each dive
-
Remove salt and sand from buttons with gentle agitation.
-
Re-lubricate O-rings as needed
-
Store in a dry, padded case between dives
Traveling with the Aquatica 7D housing is surprisingly manageable. The compact design fits into standard carry-on camera cases, and the modular port system can be disassembled for efficient packing.
