best action cameras

Photographers often talk about which is the best action cameras. For example, I have got a go pro zero seven. It is a nice one. However, it cannot focus on an image. Also, there is no zoom as in zero. Funny, I just bought at a garage sale for $20 a small coat pocket camera. It has a 30X zoom. Yeah, it is hard to believe we had such great technology years ago. Sadly, it can only shoot 1080p and not in 4K - wow.
