While the One Vision was all about the camera, the One Action is, well, all about the camera. But this time it’s a specific lens: a video-optimised shooter that’s intended to rival the likes of GoPro as an action cam.

The dedicated action camera has a 117-degree ultra-wide lens with an f/2.2 aperture, and has apparently been optimised specifically for shooting video, which will cap at HD - no 4K. However it does boast electronic image stabilisation, and one clever little tweak: the lens has been rotated 90-degrees so that you can comfortably hold the phone upright while shooting landscape video.

One side note though - the One Action hasn't been specially ruggedised or waterproofed, with only a limited IPX2 waterproof rating, so if you do want to use it like that you'll probably want to invest in a case. At least the back is plastic rather than glass though - not always a good thing, but here it means it should be better suited to handling the odd scrape or fall.

The action cam is just one part of a triple rear camera set-up, with the other two lenses used for photography and video up to 4K - though the main shooter is 12Mp, not the 48Mp monster on the One Vision, and comes paired with a 5Mp depth sensor.

The action cam shoots footage in a 21:9 aspect ratio by default - which is handy if you want to play it back on the 21:9 screen. That taller, thinner aspect ratio has so far only been seen on Sony’s Xperia 1 and Xperia 10 phones this year, and is not only better for watching movies, but also allows a larger screen - 6.3in, in this case - without it getting too wide to comfortably hold.

Elsewhere, the phone is powered by the Exynos 9609 processor, backed up (in the UK at least - other markets may vary) with 4GB RAM and 128GB ultrafast storage. That’s the same core spec as the One Vision.

A headphone jack, rear fingerprint scanner, 12Mp punch-hole selfie camera, and 10W USB-C fast-charging for the 3,500mAh battery round out the package. As with the previous Motorola One phones, it runs Android One, which means stock Android, a few Google perks, and faster security updates.

Available today from Amazon, Argos, and John Lewis, the One Action has an RRP of £219, and launches in two colours: Pearl White and Denim Blue.
