Focal Length
F stop is the focal length 

Focal length is a measure of the strength of the lens. 'angle of view' the bigger the focal length the narrower the angle of the view as seen on some of the pictures above.

Zoom lenses has many variable focal lengths where as prime has a fixed length. Prime lenses is better quality.
