Action camera innovation has plateaued slightly in the last couple of years, at least when it comes to traditional GoPro-style models.

DJI had immense success with its Osmo Pocket series, so much so that it became the number one action camera brand in Japan in 2025. The DJI Osmo Pocket 4 added 107GB of internal storage and 4K/240fps slow motion to the already excellent camera.
