A new generation of action cams is on the way - because photos and technical data of a Hero11 Black and Action 3 camera can already be found on the net from both GoPro and DJI, which indicates that they will be released soon.

So the new GoProm Hero11 Black
while not a new design is said to use a new CMOS sensor, which along with a new wide-angle lens is said to provide an even wider angle of view than before. The new sensor is said to have a resolution of 27 megapixels and record video at up to 5.3K with a maximum of 60 fps - with lower resolution 4K video, even frame rates of up to 120 fps are possible.

The photo function (which now uses 24.7 megapixels instead of the previous 23 megapixeol) is said to have been upgraded with automatic smile and blink detection, which thus takes photos independently at the right moment. In addition, GoPro&s image stabilization algorithm HyperSmooth has been updated to version 5.0 - tests will show how much this brings. HyperSmooth 4.0 should already offer "gimbal-like stabilization" according to GoPro. Both the front display and the rear touch display are unchanged since the GoPro Hero9, at 1.4" and 2.27" respectively. Likewise, just like previous models, the new Hero remains waterproof to a depth of 10 meters, and the Hero11 Black&s battery is the same as the previous model.
This means that compared to the previous model
Hero10 Black, the photos benefit slightly from the higher resolution of the sensor, but the maximum resolution and frame rate for video remain the same.
Instead, the biggest innovation is probably the leaked mini version of the Hero11 Black - which is significantly smaller due to the omitted display, but otherwise probably has the same technical specifications. It is designed for very special applications where compactness is more important than a display. As a result, the Mini is controlled via app (possibly also via voice commands), except for the start/stop buttons. Instead of the rear display, there is an additional mount there.

DJI Action 3
And also from DJI&s Actioncam Action 3 is much less known than from the Hero11: so there is already an Ohoto, on which it can be seen that the Action 3 will resemble more the (now discontinued)
DJI Osmo Actoin than the modular pre-model
Action 2 (and DJI thus in appearance back to the "classic" GoPro Actioncam design). It will be officially unveiled
on September 14. There is also already thanks to the well-known leaker @DealsDrone a
picture of the Action 3, but there it actually looks too identical to the Osmo Action to be true.

New DJI Action 3
On the
teaser video seems to confirm the leaked photo and also reveal that videos can be recorded on edge. It is supposed to be watertight up to 16 meters and a like already the Actoin 2 ( here our
test) have a magnetic quick-release system - but suffer less from a
too high heat development than this.
