The Panasonic GH4 earned a strong following in the underwater videography community thanks to its ability to capture cinematic 4K video in a lightweight and compact mirrorless body. It provides high-resolution capabilities typically associated with larger and more expensive professional gear, making it an excellent choice for both amateur and experienced underwater shooters. Its versatility, paired with an extensive range of compatible Micro Four Thirds lenses, allows users to tailor their setups to a wide variety of shooting scenarios, from expansive reefscapes to close-up macro critter behavior.
This section explores the Panasonic GH4’s core features that make it particularly suitable for underwater video, including its 4K capabilities, color profiles, ergonomics, and compatibility with external accessories. We also lay the groundwork for testing conditions in real-world diving environments to assess its performance when paired with the Nauticam underwater housing and a range of specialized lenses.
Understanding 4K Video Resolution and Its Benefits Underwater
4K video offers a resolution of 3840 x 2160 pixels, providing four times the detail of standard 1080p HD footage. This higher pixel count results in significantly sharper video, allowing for greater cropping flexibility in post-production without a loss in quality. For underwater videographers, this is particularly valuable when capturing fast-moving subjects or correcting framing issues caused by limited underwater maneuverability.
In addition to clarity, 4K video facilitates better color grading and enhancement during editing, enabling more vivid and lifelike marine imagery. When diving in environments like Southern California's kelp forests, the ability to bring out detail in green and blue hues without introducing noise is a significant advantage.
The GH4 captures 4K at up to 30fps (frames per second) in both Cinema 4K (4096x2160) and UHD 4K formats. It supports a variety of compression codecs, including IPB and ALL-Intra, offering flexibility in balancing image quality and file size. The internal recording option means videographers don’t need bulky external recorders to harness the full resolution potential of the camera, making it highly travel-friendly.
Evaluating the Nauticam Housing Design and Build
The Nauticam housing for the Panasonic GH4 is built with anodized aluminum and designed for deep diving, rated up to 100 meters. It offers complete access to the GH4’s controls, making manual adjustments possible even while wearing thick dive gloves. The control layout is intuitive, with ergonomic placement of critical dials and buttons, allowing for smooth transitions between aperture, ISO, white balance, and focus settings.
One of the standout features of the Nauticam housing is its integrated vacuum leak detection system, which enhances peace of mind before every dive. A visual and audible alert system indicates whether the housing is sealed properly. In underwater environments where equipment failure can lead to costly damage, this feature adds a layer of security.
The port system is modular, meaning you can swap out different lens ports depending on which lens is mounted to the camera. This adaptability is key when testing different focal lengths and optical characteristics underwater. For this test, flat and dome ports were used depending on the lens being tested, ensuring optimal image quality and distortion control.
Field Testing in Southern California’s Kelp Forests
Southern California’s underwater environment presents a perfect testing ground for the GH4’s video capabilities. The region is characterized by dense kelp forests, rocky reefs, and a diversity of marine life, from nudibranchs and garibaldis to sea lions and moray eels. These settings provide a range of lighting conditions, motion, and subject distances that put both the camera and lenses to the test.
Visibility in these waters varies significantly, often affected by tides, weather, and water temperature. The ability of a camera system to adjust white balance quickly and accurately is critical for adapting to rapidly changing light and color conditions. In addition, autofocus reliability and low-light performance are key factors in determining how well the camera captures fast-moving or camouflaged subjects in less-than-ideal visibility.
During the field tests, divers operated the GH4 at various depths between 10 to 30 meters. Natural light was used primarily, with occasional LED video lights added to highlight textures or details in macro subjects. The aim was to test how each lens performed in real-world underwater conditions and to identify any limitations or strengths specific to each setup.
Lens Choices and Their Impact on Underwater Video
Three lenses were chosen for this comprehensive test:
Olympus M.Zuiko 12-50mm – A versatile zoom lens capable of covering wide to mid-range focal lengths. Its macro switch function is particularly useful for capturing small subjects without switching lenses.
Olympus M.Zuiko 60mm F2.8 Macro – A dedicated macro lens offering crisp detail for close-up subjects. Its compact size and sharp optics make it ideal for capturing nudibranchs, shrimp, and other small marine life.
Panasonic Lumix G Vario 7-14mm – An ultra-wide-angle lens that excels in capturing reefscapes, schooling fish, and large subjects like kelp forests and sea lions. The lens works best with a dome port to reduce distortion and edge softness.
These lenses cover a wide range of underwater shooting styles. The goal of the test was to examine how each lens interacts with 4K resolution capture, how focus behaves underwater, and whether image sharpness is preserved across the frame. In the next section, we will look closely at each lens’s performance, supported by detailed analysis of test footage and user observations.
In-Depth Performance of the Olympus M.Zuiko 12-50mm Lens
The Olympus M.Zuiko 12-50mm lens is often celebrated for its versatility. With an effective focal range of 24–100mm in full-frame terms, this lens offers both wide-angle and moderate telephoto capabilities. What makes it especially suitable for underwater work is its built-in macro switch, which allows close focusing without changing the lens or port configuration.
Underwater, the 12-50mm was tested with a flat port, which is generally suitable for macro and mid-range shots. During dives, the macro switch feature performed reliably and allowed videographers to focus on small subjects such as hermit crabs, small nudibranchs, and gobies perched on coral heads. While this lens is not a dedicated macro optic, its ability to shift quickly between wide and close shots was valuable in fast-paced dive scenarios.
The zoom mechanism, which is electronically controlled, responded well through the Nauticam housing gear system. Although some users report minor delays or lack of tactile feedback with the power zoom, the experience underwater was generally smooth. Autofocus performance was fast in good lighting conditions, locking onto moving fish and other subjects without significant hunting.
At the wide end, however, there was some softness at the edges, which is expected when using a flat port. Barrel distortion was minimal, and color reproduction remained neutral and accurate, especially in shallow waters where natural light was abundant. The lens held up well during transitions from shaded kelp canopies to open sunlit areas, maintaining consistent exposure and clarity.
This lens’s biggest advantage is its flexibility. It allows for storytelling in diverse underwater environments without requiring equipment changes, making it ideal for divers who want one setup to do it all. While not exceptional at any one task, it provides a solid, well-rounded performance across a range of subjects.
Macro Precision with the Olympus M.Zuiko 60mm F2.8 Macro Lens
The Olympus 60mm F2.8 Macro lens is a true performer when it comes to capturing small details. Designed specifically for macro photography, this lens delivers crisp, high-resolution imagery and shallow depth of field. Mounted inside a dedicated macro flat port within the Nauticam system, the 60mm lens was put through its paces with various small marine subjects.
Underwater, it produced impressive results. The focus ring allowed precise manual adjustments, and the housing’s control gear translated movement accurately. Autofocus was responsive in both video and still modes, although, like most macro lenses, the best results came with careful manual focus and stability from the diver.
This lens truly shone when capturing minute details on nudibranchs, blennies, and sea stars. Textures, fine patterns, and even eye reflections were rendered beautifully in 4K footage. In calm water conditions, the lens was able to capture footage that appeared almost cinematic in quality, showing the benefits of pairing high-end optics with the GH4’s 4K resolution.
One consideration was working distance. Being a 60mm macro lens, it required some standoff between the subject and the lens to achieve critical focus. In surge-prone conditions or when subjects moved, it became challenging to maintain this distance. Lighting also needed to be more directional to avoid shadowing the subject with the port.
Despite these challenges, this lens delivered some of the sharpest results of the test. Its ability to isolate a subject from its background with smooth bokeh added a creative dimension to underwater video. This makes it a go-to lens for dedicated macro shooters who want to create high-detail close-ups.
Ultra-Wide Immersion with the Panasonic Lumix G Vario 7-14mm
The 7-14mm ultra-wide-angle lens brings a new level of immersion to underwater scenes. When paired with a dome port, this lens produces stunning, wide compositions ideal for shooting kelp forests, reef walls, schooling fish, and large marine life. Its full-frame equivalent focal range of 14–28mm provides expansive coverage with minimal distortion, making it highly effective for storytelling in complex underwater environments.
Underwater footage taken with this lens had a dramatic impact. Kelp fronds swaying in unison, sea lions darting in and out of view, and the full scope of reef structures were all captured with remarkable clarity. The lens’s wide field of view made it possible to keep foreground and background elements in focus simultaneously, a technique often used to add depth and scale to underwater scenes.
Color rendering was vivid and accurate, especially in daylight conditions at shallower depths. This lens handled contrast well, even in challenging backlit compositions when shooting toward the sun or reflective surfaces like fish scales. The wide aperture range and optical design allowed for minimal chromatic aberration and edge softness.
Using the 7-14mm, required thoughtful positioning to avoid bubbles, gear, or divers entering the frame. Because it captures such a large scene, the composition had to be deliberate and clean. However, once dialed in, the results were exceptional. Large subjects such as schools of fish, rocky overhangs, or human divers moving through the frame appeared cinematic and engaging.
The only challenge with this lens was flare and internal reflections in certain lighting conditions, particularly when using video lights or direct sunlight. Careful use of light placement and angle mitigated most of these issues. Overall, this lens elevated the storytelling potential of the GH4 and is an essential option for any wide-angle enthusiast.
Focus Behavior and Sharpness Testing Across Lenses
A key part of underwater video quality lies in how reliably a camera can maintain focus, especially when using autofocus. Across all three lenses, focus testing was done in both high-contrast and low-contrast conditions, using both single-point and continuous autofocus modes.
The GH4 performed well in single-point AF, especially with sufficient natural light. Focus transitions were smooth and rarely showed hunting behavior. However, in continuous autofocus, the camera occasionally struggled in backlit or murky conditions, particularly when using the 60mm macro lens. This is a common limitation of contrast-detection autofocus systems underwater.
Manual focus peaking, a feature supported by the GH4, helped address this issue by providing visual cues for achieving critical focus. This was especially useful for macro scenes where a fraction of an inch in camera movement could blur the subject. The ability to zoom in during focus adjustments further enhanced the precision of focus control.
Sharpness testing showed strong center performance across all lenses. The 60mm macro and 7-14mm wide-angle lenses delivered edge-to-edge clarity when used with the correct ports. The 12-50mm, while strong in the center, showed some softness at the extreme edges when zoomed out to 12mm. Stopping down the aperture slightly improved overall sharpness in most scenes.
These results demonstrated that when paired with the appropriate dome or flat port, the GH4 and these lenses produce high-quality footage that rivals larger sensor systems in practical applications.
Color Reproduction and White Balance Underwater
Underwater color balance is notoriously difficult due to light absorption at depth. Red disappears first, followed by orange and yellow, leaving a predominantly blue or green environment. To combat this, divers must manually set white balance or use color-correcting filters.
The Panasonic GH4 allowed custom white balance to be set quickly, even through the housing controls. Divers used white slates or sand patches as references to calibrate white balance at depth. The camera retained these settings reliably across dives and depths, producing more natural-looking footage without heavy post-processing.
Footage captured in kelp forests benefited from the GH4’s accurate green tones, showing subtle variations in fronds and foliage. When lights were added, the GH4 adjusted to mixed lighting without introducing strong color shifts or overcorrections. Skin tones, fish colors, and substrate textures were rendered true-to-life with minimal adjustments needed during editing.
Color profiles such as Cinelike D were also tested, offering a flat color response for post-production grading. This profile preserved dynamic range and was especially useful for balancing scenes with high contrast, such as sunrays streaming through the canopy or reflective fish passing in front of dark rocks.
The 4K resolution contributed to richer color detail, allowing editors to enhance specific tones without affecting the entire image. Whether capturing the electric blue of a garibaldi or the warm orange of a nudibranch, the GH4 provided the fidelity needed to bring marine life to life on screen.
Real-Time Shooting Challenges and User Experience
While the Panasonic GH4 and Nauticam housing combination offered strong performance, real-world testing highlighted a few practical challenges that divers should consider. The first is buoyancy and trim. Depending on the port and lens configuration, the setup tended to be slightly front-heavy. Adding float arms helped achieve neutral buoyancy and improved stability during shooting.
Battery life was another factor. Shooting 4K video demands significant power, and although the GH4 has decent battery performance, extended dives or back-to-back dives require extra batteries and surface charging. The housing allowed for quick battery access between dives, though this involved careful sealing and vacuum testing before re-entering the water.
Heat buildup was minimal, even when recording longer video clips. This speaks to the efficiency of the GH4’s design and its ability to dissipate heat underwater. File storage, on the other hand, required planning. 4K footage consumes large amounts of data, so high-speed SD cards (UHS-I or II) with at least 64GB capacity were used, and backups were created between dives to ensure data security.
One of the more subtle challenges was operating controls with thick gloves. While the Nauticam housing offers excellent ergonomics, some fine controls like menu navigation or white balance adjustments require familiarity and practice. Over time, divers found that scuba memory helped streamline operations even in colder water conditions.
Subject tracking also required care. Fast-moving subjects like sea lions or schools of fish moving unpredictably through the kelp canopy were challenging to follow smoothly. The camera’s internal stabilization helped, but the best results came with practiced, deliberate camera movements and proper weighting to keep the system steady.
Underwater Lighting Strategies with the GH4 Setup
Lighting is one of the most critical aspects of underwater video. Even with the clarity and dynamic range of the Panasonic GH4, the inherent color loss and shadows underwater can make footage appear dull or flat if not properly lit. During the GH4 lens tests, a combination of natural light and continuous LED video lights was used to evaluate lighting effectiveness at various depths and angles.
For wide-angle shots using the Panasonic 7–14mm lens, ambient light during daytime dives in shallow waters proved effective, especially in sunlit kelp forests. In these conditions, using the sun as a backlight created dramatic rays through the kelp canopy, enhancing depth and dimension. However, care had to be taken to avoid silhouetting subjects without proper foreground lighting.
When video lights were introduced, dual wide-beam LED lights with a high Color Rendering Index (CRI) of over 90 were used. These lights provided a soft, natural fill without overpowering the ambient light. They were particularly beneficial for mid-water subjects like fish schools and divers, as well as for capturing color detail in shaded crevices and reef structures. With the 7–14mm lens, light positioning had to be wide and angled outward to avoid hotspots and backscatter.
In contrast, when using the Olympus 60mm macro lens, lighting required a more controlled and directional setup. A single focused-beam video light or snoot was used to isolate small subjects without illuminating the surrounding area. This created a cinematic spotlight effect, helping the subject stand out in a dark or busy background. Stability was critical, as even slight hand movement could misalign the beam. Using a tripod or resting the housing on the substrate helped maintain the desired light-subject alignment.
The Olympus 12–50mm lens allowed for experimentation with both wide and close subjects, making it a versatile lens for testing different lighting approaches. When zoomed out, lights were used as fill to highlight kelp textures or fish movement. When zoomed in for macro work, the same snoot-style lighting used for the 60mm lens proved effective. The ability to zoom between focal lengths without changing lights or settings simplified the workflow.
Lighting not only brought back color but also helped improve contrast and focus performance. The GH4’s autofocus system locked onto subjects more quickly when properly illuminated, particularly in the macro range where contrast is essential for accurate focusing. White balance adjustments also became more effective with consistent light sources.
Managing Exposure and Frame Rates Underwater
Exposure settings for underwater video depend heavily on the lighting conditions and the type of subject. During the GH4 tests, the camera was typically set to shoot at 1/60 or 1/50 shutter speed when filming at 30fps or 24fps, respectively. These settings maintain natural motion blur, which is important for cinematic footage.
Aperture settings varied by lens and subject distance. For macro work using the Olympus 60mm, an aperture between f/8 and f/11 provided enough depth of field to keep the entire subject in focus, while still allowing good exposure. For wide-angle scenes with the Panasonic 7–14mm, apertures around f/5.6 were used to keep backgrounds and foregrounds sharp, balancing light intake and depth of field.
ISO settings were kept as low as possible, typically between 200 and 400, to reduce noise and preserve dynamic range. In darker conditions, or when using smaller apertures, the ISO was occasionally raised to 800, but this was accompanied by careful noise reduction in post. The GH4 performed reasonably well at higher ISOs, though noise became more noticeable in flat blue water or low-contrast areas.
The camera’s histogram and zebras were used frequently to monitor exposure. These tools helped ensure highlights weren’t blown out, especially when filming reflective subjects like fish or shooting upward toward the surface. Adjusting exposure based on feedback from these tools helped maintain consistent video quality across varying light conditions.
In terms of frame rates, the GH4 offered 24fps, 30fps, and 60fps in 1080p, while 4K was available up to 30fps. For most tests, 4K 30fps was chosen for maximum resolution and editing flexibility. However, 1080p 60fps was used when testing slow-motion capabilities, particularly with fast-moving subjects like sea lions or pelagic fish. The higher frame rate allowed for smooth slow-downs in post-production while retaining visual clarity.
File Management and Data Workflow for 4K Footage
Shooting in 4K produces large file sizes, which require a structured approach to file management. During the tests, 64GB and 128GB high-speed SD cards were used, formatted in-camera before each dive session. Cards with a UHS-II rating ensured that buffer clearing and recording speeds kept up with continuous 4K shooting, especially when using the ALL-Intra codec.
Each dive was logged with file numbers and scene descriptions to help organize footage during editing. Backup protocols involved copying footage immediately after each dive to dual external SSDs. Software tools like Adobe Bridge and ShotPut Pro helped automate backup and checksum processes to ensure no footage was lost or corrupted.
A standardized folder structure was used for each dive day, separating raw clips by lens used, lighting setup, and dive location. Metadata, including exposure settings, dive depth, and lighting conditions, was stored in log files or entered into clip comments using editing software. This documentation allowed for easy retrieval and comparison during the editing phase.
For post-production, a workstation with at least 32GB of RAM and a GPU with 8GB VRAM was required for smooth playback of 4K footage. Proxy editing was used during the rough cut stage, where lower-resolution versions of the original clips allowed for faster scrubbing and timeline assembly. Once the final sequence was locked, full-resolution media were relinked for final color correction and export.
Post-Production Techniques for GH4 Underwater Footage
The Panasonic GH4’s 4K footage holds up well during color grading and editing, thanks to its high bitrate and clean output. Most clips were shot using the Cinelike D profile, which offers a flat color curve ideal for post-production. This profile preserves more detail in shadows and highlights, making it easier to apply stylized or natural color grades.
The first stage of post-production involved correcting white balance. Even with in-camera custom white balance, slight color shifts occurred due to depth or ambient light changes. Using vector scopes and color wheels, whites were balanced using neutral reference points, such as white slates or neutral sand in the scene. This step restored natural skin tones and marine colors, particularly red and orange hues that often get lost at depth.
Next, exposure adjustments were made to balance overall brightness and contrast. Shadows were lifted slightly to reveal detail in kelp beds or reef shadows, while highlights were softened to prevent clipping in surface reflections. The GH4’s dynamic range allowed for moderate adjustments without introducing artifacts or banding.
For clips shot with video lights, saturation was increased selectively to enhance coral and fish colors without oversaturating background water tones. Midtone contrast helped bring out textures in coral, sand, and rocky surfaces, giving the footage a more tactile, lifelike feel.
Stabilization was applied to handheld clips, especially those captured in surge-prone environments. Software stabilization helped reduce micro-jitters, although the GH4’s internal stabilization already did a fair job in calmer conditions. Cropping during stabilization was minimal thanks to the high resolution of 4K, which allowed for tighter framing without degrading the final output.
Transitions between lenses required consistent grading to maintain visual coherence. Wide-angle clips were matched to macro shots by aligning contrast, temperature, and hue. The final sequences alternated between sweeping reef panoramas and tight macro interactions, creating visual rhythm and pacing that reflected the diver’s real-world experience.
Editing Lens-Specific Sequences for Visual Impact
Each lens used with the GH4 brought a distinct visual flavor to the final video. Understanding how to edit each sequence for maximum impact was critical in conveying the richness of the underwater world.
The Panasonic 7–14mm lens footage emphasized scale and movement. These clips were typically used at the beginning of sequences to establish location and environment. Long takes of divers swimming through kelp, sun rays filtering down, and passing sea life created immersive intros. Music and ambient ocean sounds helped reinforce the sense of space and tranquility.
Olympus 12–50mm clips functioned well for transitional shots. The lens’s zoom range allowed for mid-range perspectives of fish behavior, coral formations, and interactions between species. These clips often transitioned the viewer from wide scenes to close-up details. Match cuts were used to move from a school of fish in the distance to a close-up of an individual from the group.
The Olympus 60mm macro clips were saved for dramatic close-up moments. These clips captured eye movements, feeding behavior, or intricate body details. Because macro footage is slower and more intimate, music was often stripped away, leaving only subtle underwater sounds to allow the viewer to focus on the subject. Slow fades and dissolves were used instead of sharp cuts, creating a more meditative pace.
Combining all three lenses in one sequence created a layered narrative. Starting with wide scenes to draw the viewer in, transitioning to medium-range interaction shots, and finally delivering powerful close-ups, the editing flow mimicked the natural progression of a dive.
Text overlays were occasionally used to name species or explain behavior, but were kept minimal to avoid distracting from the visuals. When necessary, speed ramps and slow-motion were used sparingly to emphasize rapid movement or delicate macro detail, adding variety without overwhelming the viewer.
Visual Style and Narrative Decisions
The footage captured with the Panasonic GH4 in Nauticam housing allowed for diverse creative decisions. One style used was documentary realism, presenting scenes exactly as encountered during dives. This approach highlighted natural behavior, realistic lighting, and unaltered compositions. The GH4’s accurate color reproduction and sharpness helped support this style.
Another editing style was cinematic storytelling. By selectively color grading scenes, applying vignettes, or using stylized transitions, the footage was shaped into a narrative arc. This approach was used when editing themed sequences, such as “A Day in the Kelp Forest” or “Micro Predators of the Reef.” The cinematic style allowed for creative interpretation while preserving scientific accuracy.
Finally, abstract and experimental edits used close-up textures, motion blur, and unconventional cuts to create artistic sequences. These were less about documentation and more about evoking emotion or artistic impressions of marine life. The GH4’s 4K clarity and lens flexibility supported this artistic exploration with professional results.
Comprehensive Performance Review of the Panasonic GH4 Underwater
After extensive field testing across various conditions in Southern California’s kelp forests, the Panasonic GH4 proved itself to be a powerful and practical tool for underwater video production in 4K. Despite being a few years old compared to newer mirrorless competitors, its performance still holds up, especially when considering its portability, price point, and lens compatibility.
The GH4’s internal 4K video recording was dependable across all dives. The resulting footage was rich in detail and color, offering flexibility during post-production. Whether recording macro life up-close or large-scale scenes with wide-angle lenses, the GH4’s video clarity captured the true texture and movement of the marine environment. Custom white balance, aided by the ability to set and store multiple presets, performed reliably, allowing for consistent color correction at varying depths and lighting scenarios.
The physical controls on the camera, accessed via the Nauticam housing, were intuitive and quick to operate underwater. Key functions like ISO, aperture, white balance, and focus adjustments were easily reachable even with gloves. This allowed divers to make real-time adjustments without surfacing or interrupting the shooting flow.
Battery life was acceptable, often allowing two moderate-length dives per full charge when shooting video. However, users planning for longer dive days needed to carry spare batteries or plan between-dive charging sessions. SD card capacity filled quickly at higher bitrate settings, so managing file storage and bringing multiple high-speed cards was essential.
The GH4 did not overheat during long, continuous recording sessions underwater, which is often a concern with 4K video on compact cameras. Its cooling efficiency underwater helped maintain performance, even in warmer waters and during longer dives.
Lens Suitability for Specific Underwater Applications
Each lens tested with the GH4 served a particular role, and understanding the strengths of each was crucial for deciding which to use on a specific dive.
The Panasonic Lumix G Vario 7–14mm was ideal for wide-angle work—kelp forests, wreck interiors, and open reef scenes where scale and composition mattered most. Its ultra-wide field of view allowed creative framing with close foreground subjects and distant backgrounds, a key feature in professional underwater storytelling. Its performance was best when paired with dome ports that minimized distortion and preserved edge-to-edge sharpness.
The Olympus M.Zuiko 12–50mm shined as a hybrid lens for situations when the diver didn’t want to commit to either wide-angle or macro before jumping in. Its macro switch enabled pseudo-macro capability without changing lenses, making it ideal for casual dives where subject variety was high. However, it lacked the razor-sharp detail and subject separation found in more specialized optics.
The Olympus M.Zuiko 60mm F2.8 Macro lens was a precision tool for dedicated macro videographers. It revealed the subtle details of tiny sea life with impressive clarity. Though it required patience, good buoyancy control, and careful lighting, the payoff was professional-quality macro footage that rivaled higher-end setups. It was less versatile than the zoom lenses, but delivered better results for focused macro sessions.
Advantages and Limitations of the Nauticam Housing
The Nauticam housing provided a reliable platform for deploying the GH4 underwater. Its ergonomic design, rugged build quality, and vacuum-sealed safety features made it a trusted piece of gear. Customization options, such as adjustable control gears for different lenses, wide port compatibility, and optional handles or arms, made it suitable for all user levels.
One of the most appreciated features was the integrated vacuum system with leak detection, which instilled confidence before every dive. The visual indicator was easy to interpret and gave divers peace of mind when submerging valuable equipment.
However, the housing did have some limitations. For newer users, the bulk of the full system (camera, lens, housing, dome, lights) required proper trim and buoyancy adjustments. Without float arms, the rig could become cumbersome over long dives. Some of the smaller controls, such as menu navigation or diopter adjustments, were more difficult to use with gloves in cold water.
Despite these minor drawbacks, the Nauticam system proved to be highly functional and dependable for real-world underwater use.
Practical Recommendations for Underwater Filmmakers
For divers interested in capturing 4K underwater video with a system that balances quality, size, and cost, the Panasonic GH4 paired with the Nauticam housing is a strong contender. It is suitable for hobbyists aiming to build their underwater videography skills, as well as experienced shooters who need a lightweight secondary rig for travel or quick dives.
