Very Thanks for everyone who is reply to my question about the focal length.

The zoom rating, e.g. 50x is relative to the shortest focal length and the longest.  The FOV you get will depend on the size of the image sensor along with the focal lengths.  So a 50x camera from one brand may give a different zoomed in FOV than another brand's 50x camera.
