For H20/H20T, the hybrid focal length for maximum optical zoom is 5562mm, any hybrid focal length which is greater than 5562mm is digital zoom. The theory of digital zoom is actually magnify the picture. Therfore, the actual focal length will not change so that the setFocusStateCallback will not be trigger either.
Why the setFocusStateCallback has no callback return when H20/H20T's hybrid focal length is greater than 5562mm?
