DJI has announced (and released) the Action 6, an update of their action camera with an adjustable mechanical aperture and a larger square sensor which they promise will make cropping to different aspect ratios. I have an Action 3 and a 4, and I’ve been very happy with both cameras (apart from their picky insistence on particular SD cards). I tend to buy them one generation behind the current version, and I have no real need for a third right now, but I’ll keep an eye on these.
