DJI OSMO Action 4 specs leak ahead of upcoming release, indicating larger sensor and 4K 120 FPS video repeat ^↺

DJI is known for its camera accessories, drones, and compact, affordable action cameras. While the company has not announced anything concrete about its next-generation OSMO Action 4 camera, the alleged specifications have been leaked on Twitter by @camerainsider. The proposed leaked specifications paint a picture of a significant hardware update behind a minor feature upgrade.

For the most part the specifications look very similar to the outgoing OSMO Action 3 camera, with a 155° field of view, a maximum video resolution of 4K 120 FPS, and an aperture of f/2.8. One intriguing detail that may result in a substantial improvement to low-light performance, though, is the new sensor size.

The alleged OSMO Action 4 spec sheet indicates that the new camera will come with a 1/1.3-inch sensor. Compared to the outgoing 1/1.7-inch unit, that's a welcome 69% increase in sensor surface area. This increase in sensor size means that the new camera should perform much better in low-light scenarios, despite the same f/2.8 aperture. Close-up shots should also provide more background separation, although this is unlikely to be an important consideration for prospective action camera buyers. 

Other miscellaneous improvements include a two-metre increase in the case-free waterproofing rating — from 16 m (52.5 feet) to 18 m (59 feet) — while the weight is slated to stay around the same 145g mark.

DJI itself shared a teaser of a July 25 product launch on YouTube, indicating that a new product with a dual-display or dual-sensor configuration will arrive on the specified date. The teaser is deliberately vague, but it could be for the Action 4 or the upcoming Air 3 drone, with the latter seeming more likely, since the person in the video teaser seems to be holding a remote control. It's not impossible that DJI would release an action camera around this time of year, but it has historically launched them closer to October.
