YI LITE Action Camera

I do a lot of mixed video-type things. Currently, I have a GoPro, and I have a tripod for it. I build videos on cars and drones, so I set it up and use it as a "studio" camera type thing. It's high quality and wide-angle, so it's great for "hands-on" type content. I really want to get into outdoors stuff, POV driving, drone video, and POV photography (outdoors and in public), I feel like the GoPro strapped to my head is just too large and draws too much attention. I also have to say that any chest mount I get for it is about the same size as a bulletproof vest, and as a result, is extremely bulky and draws attention as well. I'm looking for something that will have just as good quality and be able to do wider shots when I am working with things close up, while also being a good bit smaller/inconspicous than the GoPro so I can go out into public while recording without drawing too much attention.

Does anyone know how good the Sony to cannon adapters are in practice with video and autofocus, will it work for fast pans and zooms filming sports and outdoors? I want the camera to be best value for money and to be able to grow with the camera as my abilities improve, thinking about learning colour grading etc. I want the camera to be practical for shooting action adventure and daily life as described earlier, I do also like features tailored towards creators as I am on TikTok but don’t really want a basic ‘creator camera’ I want high quality video and option for photos.
