The best action cameras for swimming

Swimming is three different jobs

Every other page in this hub starts with what the boat does to the camera. Here there is no boat, so the question is what you are swimming for — and the three answers want genuinely different setups.

Pool laps and technique. You want the camera static and you want to swim past it: on the pool edge, propped at the end of the lane, or held under by a coach. Nothing is attached to you, image quality under artificial light matters, and the session is short. This is the easiest of the three and the one where the cheapest camera on the list is genuinely fine.

Open-water swimming. A lake, a reservoir, a sea swim, a triathlon leg. Now the camera has to come with you, nothing is static, the light is bright and flat, and you are far from the thing you left on shore. Weight, battery and a way to attach the camera to your head decide this entirely.

Play swimming. Kids in a pool, a holiday, jumping off a dock. Handheld most of the time, passed around, dropped regularly. Here a float is not a nice-to-have, it is the product, and ease of use beats every spec on the box.

The ranking above weights the second and third cases, because the first one barely needs a buying guide: set any waterproof camera on the edge and swim.

How we ranked these

Five criteria, ordered by how much they actually change the footage you come home with. The full scoring rubric sits above the picks; this is what the weighting means in the water.

Where the camera goes when both arms are swimming

There are four workable positions and two that people try anyway. Worth knowing which is which before you buy a mount.

The goggle strap. The natural swimming mount: low profile, roughly eye-line, and no separate harness. It only works with a light camera — this is where the 53g GO Ultra genuinely beats cameras that are better in every other respect. Run the strap through something mechanical; a magnet is not enough once you push off a wall.

A head strap or swim cap. Slightly higher and more stable than goggles, and it takes a full-size camera. The honest trade is that a flagship on your forehead creates drag and pulls your head up, which is exactly the fault most swimmers are already working on. Fine for a relaxed open-water swim, not for a technique session.

A floating hand grip. The right answer for play, treading water and breaststroke, and the one that survives being handed to a child. It is useless for freestyle.

Static, in or beside the pool. The forgotten option and the best one for technique: put the camera on the pool edge or weight it on the bottom in the shallow end and swim past it. No mount to buy, no drag, and the footage is steadier than anything worn.

Pools: the things that are different indoors

You do not need a filter. Red filters exist to put back the color that open water strips out over distance, and a pool has neither the depth nor the distance for that to happen — the far wall is 25 meters away and the water is clear. A filter in a pool just makes everything warm and wrong. The filter guide covers where they do earn their money, which is open water and reef.

The blue cast is the tiles, not the water. Pool footage looks blue because the pool is painted blue and the light bounces off it. Setting white balance manually on deck, before you get in, fixes more of it than any color grade afterwards.

Indoor pools fog cameras. Warm, humid air plus a camera that has been sitting in a cold car equals condensation, sometimes inside the lens cover. Let the camera sit in the pool hall for ten minutes before you start, and if you use any kind of case, use anti-fog inserts — they cost very little and they are the only thing that reliably works.

Check the rules before you film. Plenty of public pools and leisure centers restrict or ban cameras outright, and the ones that allow them usually want you to ask first and to avoid filming other people's children. That is not legal advice, it is just how to avoid being asked to leave halfway through a session. Lane swim at a quiet hour, or ask the duty manager.

Open water: what actually goes wrong

You lose things in a lake. A camera that comes off your goggles in a pool is on the bottom of the pool, visible, in two meters of clear water. The same event in a lake is a lost camera. A float and a short tether is the cheapest insurance on this page, and the one most open-water swimmers skip.

The surface is a mirror. Swimming puts the lens at water level pointing into glare for most of the session, which is the single worst exposure condition we cover. Swim with the sun behind you where the course allows it, and expect every sighting shot into the sun to be a silhouette.

Cold eats battery, and then it eats the session. Published runtimes are measured warm. Open water in spring or autumn will take a meaningful bite out of the figures above, which is part of why the DJI bodies, rated to -20°C, rank where they do.

The camera is not a safety device. Worth saying plainly: do not swim further, longer or alone to get a shot, and do not stop in cold water to fix a mount. A tow float is a swimming purchase, not a camera purchase, and it comes first.

Chlorine, salt and the five minutes afterwards

Chlorinated water is not gentler on a camera than lake water — it is harder on seals and O-rings over a season, and the residue it leaves behind as it dries is the part that does the damage. The routine is the same one we publish for salt: rinse the camera in clean fresh water while the doors are still closed, dry it before you open anything, and do not let it dry out with residue sitting in the door seal.

It takes two minutes and it is the difference between a camera that lasts two seasons and one that lasts eight. The full version, including why you dry before you open, is in salt water care and rinsing — everything in it applies to a chlorinated pool.
