# Best Underwater Cameras for Scuba Diving (2026)
I'll save you from the rabbit hole I fell into: start with a GoPro or similar action cam. Shoot with it for 50 dives. Figure out what frustrates you. Then upgrade based on that.
The reason this advice works: underwater photography is a completely different discipline than topside shooting. What limits you isn't the camera — it's the water. Particles, color absorption, backscatter, subject distance. No amount of megapixels fixes physics.
Here's the full breakdown anyway, because you're going to fall into the rabbit hole regardless.
Categories
Action Cameras ($300–$500)
GoPro Hero 13 Black (~$400)
The default starter camera for divers. Waterproof to 10m without a housing (get the $50 protective housing for depth). 5.3K video, excellent stabilization, tiny form factor. Clips to your BCD or mask mount.
Pros: Small, simple, great video, cheap to start. Wide angle captures the scene. Cons: No manual exposure control underwater. Wide lens means everything looks farther away. Still photos are mediocre in low light.
DJI Osmo Action 5 Pro (~$350)
GoPro's main competition. Slightly better low-light performance, magnetic mounting system, dual screens. Waterproof to 20m without housing.
Pros: Better battery life than GoPro, excellent stabilization, good value. Cons: Fewer underwater accessories available, slightly less reliable in salt water long-term.
My take: Either camera is excellent for starting. The GoPro ecosystem (mounts, housings, filters) is larger. But the DJI is a better camera in some metrics. You can't go wrong.
Compact Cameras ($400–$1,200)
Olympus/OM System TG-7 (~$550)
The indestructible standard. Waterproof to 15m without a housing. Add the PT-059 housing ($300) for diving to 45m. This camera has been the workhorse of underwater photography for years.
Pros: Rugged, macro mode is excellent (close-up shots of nudibranchs and tiny critters), RAW shooting, microscope mode. The f/2.0 lens is fast. Cons: Small sensor means more noise in low light. Limited wide-angle without add-on lens. Video is decent but not action-cam level.
The TG-7 is the camera I recommend for divers who want better stills than an action cam provides but don't want to spend $3,000+.
Mirrorless in Housing ($2,000–$5,000 total)
This is where underwater photography gets serious (and expensive). A mirrorless camera in a dedicated underwater housing gives you manual controls, interchangeable lenses, and image quality that compacts can't match.
Sony a6700 (~$1,400 body + $1,500–$2,500 housing)
APS-C sensor, fast autofocus, excellent video (4K 120fps), compact body. Housings from Nauticam, Ikelite, and Sea & Sea are well-established.
OM System OM-5 (~$1,200 body + $1,200–$2,000 housing)
Micro Four Thirds sensor. Smaller than Sony, which means smaller (cheaper, lighter) housings. The OM-5 has excellent in-body stabilization and weather sealing. Great for travel-focused divers.
Total system cost with one lens and housing: $2,500–$5,000. Add a strobe or video light: another $500–$1,500.
Full Frame in Housing ($5,000–$15,000+)
Overkill for 95% of divers. But if you're serious about underwater photography or shooting professionally:
Sony A7RV (~$3,900 body + $3,000–$4,000 housing)
61 megapixels. Ridiculous dynamic range. AI-powered autofocus that tracks fish eyes. The best stills camera you can put underwater.
The housing is the size of a small suitcase. The total system (body, housing, ports, strobes, arms) easily exceeds $10,000. You'll need a dedicated gear bag. Your dive buddies will hate you for taking 20 minutes to set up.
What Actually Matters Underwater
Lens Port: Dome vs Flat
- Dome port: Corrects for refraction underwater. Essential for wide-angle lenses. Subjects appear natural size and distance.
- Flat port: Magnifies subjects by ~33%. Good for macro. Causes distortion with wide-angle lenses.
Strobe vs Video Light
- Strobes (flashes): Freeze motion, bring back color at depth, minimal backscatter when aimed correctly. Essential for serious still photography.
- Video lights: Continuous light, works for both video and stills. Easier to aim (what you see is what you get). Attracts plankton, which can cause backscatter.
Buoyancy
Camera rigs affect your trim. A heavy camera in front of you pitches you forward. Housing manufacturers publish buoyancy specs — aim for slightly negative (sinks slowly) or neutral.
Add float arms to your strobe/light setup to offset weight. A neutrally buoyant rig is dramatically easier to handle over a 60-minute dive.
My Honest Recommendation
Dive 1-50: GoPro Hero 13 or DJI Osmo Action 5. Clip it to your BCD. Learn to dive first. A camera in a new diver's hands is a distraction from buoyancy and safety fundamentals.
Dive 50-200: If stills matter to you, get a TG-7 with housing. If video is your thing, the GoPro is honestly hard to beat.
Dive 200+: If you're still shooting and wanting more, invest in a mirrorless system. By now you know whether you prefer wide-angle or macro, which determines your lens and port choices.

I'm Chad. Chemist. Diver. I shot 200 dives on a GoPro before upgrading. My best underwater photo was taken with that GoPro. The camera matters less than you think. Being in the right place matters more.
