The OM System TG-7, the much-anticipated successor to the popular Olympus TG-6, has finally arrived. Known for its reputation as a go-to compact camera among underwater photography enthusiasts, particularly macro shooters, the TG-6 earned widespread praise for its durable design and specialized features. When Olympus was acquired by Japanese Industrial Partners and rebranded as OM System, many expected a significant overhaul in their next flagship tough camera. With six years having passed since the launch of the TG-5 and four years since the TG-6 made its debut in 2019, the photographic community was looking forward to a model that would push boundaries and bring meaningful improvements to underwater and adventure photography. Unfortunately, the TG-7 delivers only minor updates over its predecessor—raising questions about whether it is worth the new $549.99 price point.
A Look Back and Expectations for the TG-7
Back in 2019, the TG-6 made waves by offering unique features like microscope mode, RAW shooting, and excellent macro performance—all in a compact and rugged body. Fast forward to 2023, and many expected OM System to break new ground with a revamped model. However, the TG-7 retains almost all of the same specifications as the TG-6. While some small changes have been made, most are not especially significant for underwater photography enthusiasts. Despite this, the TG-7 comes with a higher price tag, making other entry-level mirrorless cameras like the Canon R100, priced at $479, appear more appealing for budget-conscious users.
First Impressions and Field Testing
Despite the similarities, we took the TG-7 into the field to see how it performed in real-world conditions. We tested the camera extensively during dives in the Pacific Northwest and Hawaii. Even though many of the sample images may look familiar to TG-6 users, this field test was essential to verify whether the TG-7 can still meet the expectations of photographers in challenging environments. The camera was paired with an Ikelite TG-7 housing for underwater use, and additional accessories from Inon were utilized to explore its full potential.
Compatibility with TG-6 Underwater Housings
One clear advantage of the TG-7’s minimal redesign is its full compatibility with TG-6 housings. This is excellent news for current TG-6 owners who already invested in underwater gear. Housings such as the Ikelite TG-7, Marelux, Isotta, Kraken, Nauticam, and the Olympus PT-059 work seamlessly with the TG-7, offering flexibility and reducing the need for new investments in gear.
Hands-On Experience with the Ikelite TG-7 Housing
During our Hawaii dives, we used the Ikelite TG-7 housing, which stood out for its compactness, clarity, and usability. The housing is easy to operate, even for beginners. Each button is clearly labeled, the back of the housing is transparent, and inserting the camera is a straightforward task. Our dive buddy, Avyay—a novice diver and first-time underwater photographer—was able to capture impressive manta ray shots on his very first attempt using this setup. The Ikelite housing is also the only one that supports the FCON-T02 fisheye lens, which is ideal for creating a true wide-angle setup.
Performance with Inon Accessories
Back in the Pacific Northwest, we tested the TG-7 with Inon’s latest accessories. These included the Inon S220 strobe, mega float tubes, telescopic arms, and wide-angle lens attachments. The accessories added functionality and flexibility, especially for macro and close-up work. The S220 strobe, in particular, enhanced image clarity and lighting control in darker underwater conditions, where the camera’s native capabilities can be limited due to its small sensor.
What's New in the TG-7
Although the TG-7 has disappointed some fans expecting a major upgrade, it does introduce a few minor changes. The most notable is the transition to a USB-C port for charging and data transfer, a much-needed modernization over the TG-6’s outdated micro USB. Additionally, the camera now supports automatic video rotation for vertical video recording, catering to social media content creators. A new construction mode has also been introduced for industrial applications, although this is of limited relevance to underwater photographers.
Specifications Summary
The OM System TG-7 is equipped with the same 12-megapixel 1/2.33" sensor found in the TG-5 and TG-6, paired with the Olympus TruePic VIII processor. It's fast f/2.0–4.9 lens offers a focal range equivalent to 25–100mm and is supported by sensor-shift image stabilization. The camera includes custom white balance settings, multiple autofocus modes, and 4K video recording at 30 frames per second. There’s also a high-speed video mode and Pro Capture mode for burst photography. For macro enthusiasts, the minimum working distance of 1cm remains unchanged. WiFi functionality, built-in flash, and GPS-based tracking features round out the package. Battery life is rated for 330 shots, though real-world use suggests swapping batteries after each dive may be wise.
Image Quality and Use Cases
The TG-7’s image quality is on par with its predecessors. Its performance excels in macro photography, especially under good lighting conditions. With the microscope mode enabled, fine details can be captured that many cameras would miss. However, in low-light scenarios or for wide-angle shots, the camera's small sensor becomes a limiting factor. Our test dives in the Pacific Northwest produced images with noticeable noise at ISO 640, underscoring the importance of proper lighting and strobe use for wide-angle compositions.
Build Quality and Durability
Like previous models, the TG-7 is rugged and reliable. It is freeze-proof to -10°C (14°F), crushproof to 100 kg (220 lbs), shockproof from heights up to 2.1 meters (7 feet), and waterproof up to 15 meters (50 feet) without a housing. This makes it a resilient choice for divers and adventurers who demand durability in harsh conditions. While underwater housings are necessary for deeper dives, the native waterproofing adds a layer of safety in case of minor leaks or exposure to water during transport.
Battery Life and Recommendations
Battery performance has not seen improvement in the TG-7. Just like with the TG-6, the camera is rated for about 330 shots per charge. Based on our experiences, users who take many photos or shoot video during dives should expect to change the battery frequently. It is advisable to carry extra batteries when planning multiple dives or extended photo sessions to avoid running out of power mid-dive.
In-Depth Image Quality Analysis
The OM System TG-7’s imaging pipeline is built on a 12-megapixel 1/2.33" sensor and the TruePic VIII processor, the same setup used in its predecessor, the TG-6. On paper, these specifications may not inspire confidence in a world where 20-megapixel 1" sensors are becoming the norm in compact cameras. However, for its size, the TG-7 manages to deliver respectable image quality—particularly in well-lit scenes and macro conditions. The TG-7’s performance is highly situational and is best understood by breaking down the results in various types of shooting environments.
In bright daylight, above or below the water, the TG-7 renders colors with impressive vibrancy. The in-camera JPEG processing produces contrast-rich images that rarely need major post-processing unless the dynamic range is severely challenged. Fine detail is preserved fairly well at base ISO (ISO 100–200), but the image starts to show softness and noise reduction artifacts at ISO 400 and beyond. For macro images, this is rarely an issue since most subjects are shot in controlled lighting using strobes or diffusers.
In low-light settings or deeper underwater environments where natural light is limited, the camera struggles to maintain clarity. As ISO climbs past 800, digital noise becomes more apparent, and details get muddy. Shadow recovery in RAW files is limited by the small sensor’s narrow dynamic range, and aggressive noise reduction often smears fine textures. This limits the effectiveness of the TG-7 for wide-angle underwater photography in dim conditions, like deep wreck dives or dusk reef explorations.
Color accuracy is consistent with the TG-6 and leans slightly towards cooler tones underwater. White balance can be adjusted manually or set using custom slots, allowing the photographer to fine-tune temperature shifts caused by artificial lighting or varying depths. The TG-7 also supports RAW shooting, which gives divers the ability to adjust white balance, exposure, and tone curves more effectively during post-processing.
JPEG vs. RAW Shooting
One of the standout features of the TG-7 is its support for RAW capture. This is relatively rare in rugged compact cameras and allows photographers to extract significantly more detail from shadow areas, correct white balance issues, and apply sharpening selectively. RAW files from the TG-7 contain more data than JPEGs and offer greater control over final image aesthetics.
However, RAW files from a 1/2.33” sensor are still limited in terms of latitude. They don’t recover highlights as gracefully as larger sensors, and pushing exposure too far in post often results in noisy or flat-looking images. That said, for macro work, where subjects are well-lit with strobes and shadows are controlled, RAW files allow precision editing of color and fine textures.
JPEG shooters will find that the TG-7’s in-camera processing produces good results straight out of the camera. Olympus’s color science has always leaned toward vibrant blues and punchy reds, making coral reefs and tropical fish pop with minimal post-production. Scene modes such as “Underwater Macro” and “Underwater Snapshot” apply camera presets that enhance contrast and saturation to suit underwater environments.
4K and High-Speed Video Performance
In addition to photography, the OM System TG-7 also provides various video capabilities. It's 4K/30p video is compressed at around 102 Mbps and offers good sharpness and color reproduction under ideal lighting. As with still images, video quality is best in bright, shallow waters where natural light enhances the small sensor’s output. The autofocus system in video mode does a reasonable job of maintaining subject sharpness, especially in one-shot AF mode. Continuous autofocus is slightly jittery but usable when subjects are slow-moving.
One standout video feature is the TG-7’s high-speed recording capability. It can shoot Full HD video at 120 frames per second, 720p at 240 fps, and 360p at 480 fps. These settings allow creative slow-motion effects, useful for studying marine life behavior or producing cinematic underwater clips. The trade-off is reduced resolution and increased noise in lower light.
A newly introduced feature in the TG-7 is automatic vertical video rotation. When shooting in portrait orientation, the camera automatically tags the video to play back vertically—perfect for social media stories and reels. This feature doesn’t directly improve video quality, but it makes the workflow easier for creators who frequently post mobile-first content.
For divers planning to use the TG-7 for video work, an external lighting setup is essential. The built-in flash cannot be used for continuous lighting during video recording, and relying on ambient light will restrict you to shallow, clear water environments. Attaching a video light with an adjustable beam and color temperature provides far superior results in capturing detailed, noise-free footage.
User Interface, Menus, and Customization
The TG-7’s user interface is designed for ease of use. With dedicated buttons for essential controls, a user-friendly menu system, and multiple shortcut options, the camera is equally approachable for beginners and customizable for experienced shooters. Even within a housing, the controls are logical, with each setting accessible through labeled and responsive buttons.
Menu navigation is divided into straightforward categories, and users can assign custom functions to specific buttons. For example, if you shoot mostly macro underwater, you might assign microscope mode and manual focus to quick-access slots. There are also four custom modes (C1–C4), where you can store preferred settings. These are extremely useful for underwater photographers who need to switch between macro and wide-angle setups quickly.
The LCD screen, while not a touchscreen, is bright and color-accurate enough to judge composition and exposure. Underwater, the clarity of the screen helps verify sharpness, although reflections and ambient light may occasionally obscure visibility. The TG-7 does not include an electronic viewfinder, which is common for cameras of its class, but some users may miss this feature when shooting in glaring surface light.
Ergonomics and Handling with Gloves
Handling the TG-7 with gloves underwater is generally comfortable, especially when inside a well-designed housing. The camera body itself is compact and solid, with a rigid grip for secure handling. All compartments are sealed tightly, and a double-locking mechanism prevents accidental openings—an essential feature for underwater or rugged use.
In colder waters, thick gloves can make button pressing more challenging. However, housings like the Ikelite model mitigate this by using large, easy-to-press external buttons. Each control is clearly labeled, and the layout mimics the camera’s native interface, which means there’s virtually no learning curve when transitioning from land to underwater shooting.
The camera’s lightweight nature makes it easy to carry and manage even during long dives. With the addition of buoyancy accessories like float arms, you can achieve neutral buoyancy, further improving comfort and maneuverability. This ergonomic setup is especially important when composing delicate macro scenes, where stability and precision are critical.
Durability Testing and Environmental Use
Beyond underwater photography, the TG-7’s rugged credentials are impressive. Its ability to withstand freezing temperatures, crushing pressure, and accidental drops makes it highly versatile. These features make it suitable not only for divers but also for climbers, kayakers, wildlife trackers, and field scientists who work in extreme environments.
We performed real-world durability tests on the TG-7, including exposing it to snow, rain, sand, and impacts from low-height drops. The camera continued to function without issue in all conditions. Its sealed body prevents dust and water ingress, and the lens is protected by an anti-fog, scratch-resistant glass. This means that even when not used in water, the TG-7 is one of the few cameras you can confidently toss into a bag without worrying about damage.
One small improvement would have been a built-in lens cover. The current design exposes the lens to possible smudges or scratches if not handled carefully on land. Users often address this by using housing or aftermarket covers, especially when traveling in environments where dust and grit are common.
Connectivity and Smart Features
Modern adventure cameras are expected to integrate with smartphones and other devices, and the TG-7 meets these expectations with built-in WiFi capabilities. The camera can connect to the OM Image Share app, which allows users to transfer photos wirelessly, add GPS tags, and even control the camera remotely.
Remote shooting is a useful feature for capturing wildlife or group photos where the camera needs to be positioned in a specific location. While not essential for underwater use—due to the limitations of wireless signals underwater—it can be helpful for surface shots or setting up on boats or docks.
GPS tracking is supported by onboard action sensors, which also record data such as altitude, direction, temperature, and depth. This makes the TG-7 attractive to scientific users who need to log environmental data alongside images. The data is stored in the metadata of each image and can be viewed using desktop software or compatible mobile apps.
Battery Life and Power Management
The TG-7 maintains the same battery performance as the TG-6, with a CIPA rating of 330 shots. While sufficient for casual photography, this rating drops in real-world use—especially during cold water dives, long exposure sessions, or video recording. When diving, power management becomes a key consideration. Using LCD screen brightness at its lowest acceptable level, disabling GPS when not needed, and avoiding continuous video recording can help extend battery life.
We recommend bringing at least two spare batteries on dive trips. Charging is faster and more convenient now with the addition of USB-C, which allows direct connection to modern chargers and power banks. However, you cannot charge the camera while it’s in a housing, so planning is critical.
If you’re planning extended excursions without access to power, you may want to invest in a dual battery charger and high-capacity power bank. This ensures you can charge multiple batteries overnight or during breaks between dives.
Final Thoughts on Image Quality and Usability
The OM System TG-7 strikes a careful balance between portability, ruggedness, and macro performance. Its image quality, while not competitive with larger sensor systems, is perfectly adequate for a wide variety of conditions and especially strong in controlled macro environments. The usability is superb, making it accessible to both beginners and experienced photographers.
Its biggest strength remains in its ease of deployment. No camera in its class can go from your backpack to the ocean floor as quickly or as reliably. Its shortcomings—primarily limited dynamic range and poor low-light wide-angle capability—are expected trade-offs for its compact form and rugged build.

Real-World Performance and Final Thoughts
The OM System TG-7 is at its best when pushed to its limits, and few environments test a camera like the ocean. Designed for underwater use up to 15 meters (50 feet) without a housing, it is a favorite among snorkelers, divers, and marine biologists. The anti-fog dual-pane glass is highly effective at preventing condensation, and the camera transitions seamlessly from dry land to wet environments without the typical lag in focusing or sensor confusion.
The microscope mode also shines underwater, offering users the ability to capture extreme close-ups of coral textures, tiny crustaceans, or the minute patterns on shells. Unlike DSLRs or mirrorless setups that require expensive macro lenses and housings, the TG-7 handles these delicate situations without extra gear. For casual underwater photographers and professionals alike, this is a game-changer.
Additionally, the TG-7 has proven capable in snowy and freezing conditions. During alpine tests at -10°C (14°F), the camera remained operational while many smartphones froze or became unresponsive. Snowboarding and ice climbing enthusiasts have appreciated the rugged grip and responsive buttons that can be operated with gloves.
Battery Life in the Field
Battery life on the OM System TG-7 is modest, with a single charge lasting about 300 shots in standard conditions. However, intensive GPS logging, Wi-Fi usage, or 4K video recording can cut that down significantly. To its credit, the TG-7 recharges relatively quickly via USB-C, and extra batteries are affordable and easy to carry.
For fieldwork or travel in remote regions, it’s best to pack 1-2 spare batteries. Fortunately, the camera's compact body makes that an easy choice.

These accessories attach easily and are built to match the rugged construction of the TG-7, extending its utility across many photographic genres.
Image Processing and Color Accuracy
Photos out of the OM System TG-7 tend to be vibrant and slightly contrasty, especially in iAUTO or scene modes. The camera leans into a consumer-friendly JPEG profile with vivid blues, rich greens, and well-exposed skin tones. That said, users who shoot in RAW will find a surprising amount of flexibility in post-processing. Shadows can be recovered without significant noise, and color grading works well due to the accurate white balance.
For underwater photographers, the white balance presets and underwater modes correct color shifts caused by water depth. These modes neutralize the bluish or greenish tint that dominates underwater scenes, restoring natural-looking reds and yellows.
GPS and Field Sensor Suite
One of the standout features of the TG-7 is the integrated field sensor system. It includes a GPS, barometer, thermometer, compass, and accelerometer. These tools serve a dual purpose—enhancing your understanding of the environment and enriching metadata for photos.
Adventure travelers and field researchers benefit from having this information embedded into their images. Not only can you track your altitude, heading, and temperature at the time of shooting, but these details are helpful for storytelling, mapping, or scientific data collection.
OM System’s OI. Track app allows for syncing this information with your smartphone, and logs can be exported or shared easily.
Low Light and Indoor Performance
While the TG-7 is not a low-light powerhouse, it handles dim conditions fairly well, thanks to its f/2.0 lens at wide angle and ISO flexibility. Indoors, the camera delivers decent results if the subject is well lit or motionless. However, noise becomes more pronounced above ISO 800, and autofocus can slow down slightly in darker environments.
The built-in flash helps in close quarters and works well for fill light. Macro users especially appreciate the ability to light tiny subjects directly without casting harsh shadows.
Video Capabilities
For video enthusiasts, the TG-7 supports 4K recording at 30 fps and Full HD at 60 fps. The footage is sharp, with natural colors and steady exposure transitions. Video stabilization, however, is limited, and there’s no microphone input, making the TG-7 a less-than-ideal choice for vloggers or cinematic shooters.
On the flip side, the camera's ability to shoot video in harsh environments makes it excellent for capturing real-world exploration footage—kayaking, rafting, mountain biking, or trekking. Time-lapse, high-speed recording (slow motion), and interval shooting modes offer extra creative potential.
Usability for All Skill Levels
The TG-7 is exceptionally beginner-friendly. Its auto modes and intelligent scene recognition reduce the learning curve, while its physical durability gives users the freedom to focus on the shot rather than worry about damaging the gear. For more experienced users, manual controls are available, though limited to basic exposure adjustments.
Menus are intuitive, and the mode dial provides instant access to main functions, including dedicated positions for underwater and microscope modes. The lack of a touchscreen is notable, but the responsive D-pad and buttons compensate well in extreme environments.
