question

I've looked all over and can't find it. Does anybody know what the focal length of the built in lens on this camera is?
Asked by: Matthew
We couldn't find that either. However, since it is very much like the most popular action camera, we will be of the opinion that the focal length is the same or there about of 2.9mm.
