DJI Osmo Action 6

Cab-ride style footage and window shots reward a camera that copes with changing light. Trains pass from open daylight into tunnels, station canopies and cuttings within seconds, and the Osmo Action 6 pairs a larger sensor with a lens whose aperture runs from f/2.0 to f/4.0. TechRadar's reviewer found image quality superb in bright light and highly impressive in dim surroundings, with fine-grained noise in moderate low light. On DJI's specification it records 8K at up to 30 fps and 4K at up to 120 fps, which gives room for slow motion of a passing consist. The reviewer also notes the body is similar in size to earlier models and slips into a coat pocket, which suits a long day of lineside waiting.

DJI specifies 20 m without a case and an IP68 waterproof standard, provided the battery and USB-C covers are closed, so rain and spray are within its limits. TechRadar's reviewer found the touchscreen stayed responsive when the camera was wet, saw droplets shed quickly from the lens, and judged it more practical in cold weather than portrait-oriented rivals. DJI lists operation from minus 20 to 45 degrees Celsius. In the review a single charge lasted about four hours of mixed 1080p and 4K recording, though battery life fell as the temperature dropped, so carry spares for a winter day on a platform. RockSteady stabilization produced tracking and walking shots free of micro vibrations, which helps with handheld footage from a train window, although the reviewer says it does not replace a gimbal. The attachment point was called fiddly, so test your mount before you rely on it at a fixed position. Film only from places where you are permitted to stand, and never place a camera or mount on or near the running line.

Expert pick · TechRadar: TechRadar's reviewer tested a production unit over several days and found image quality superb in bright light and very good in dim light, with an easy interface and long battery life. The review recommends it to experienced shooters and notes a smaller accessory ecosystem than GoPro's. Read the review

It suits railfans who film more than they photograph and who want one small camera for daylight, dusk and tunnel shots. The reviewer calls it designed for experienced videographers, so a complete beginner who wants point-and-shoot simplicity, or someone who already owns many GoPro mounts and lens mods, may be better served elsewhere.

The GoPro HERO13 Black has the broader accessory range and 5.3K video, and TechRadar calls it the camera others are judged against, though its low-light footage trails. The Insta360 Ace Pro 2 offers a larger flip-up screen and a quick-release magnetic mount if framing from a distance matters more.
