By a zoom lens I assume you mean a telephoto (long focal length) lens, as zoom implies a variable focal length. There are no f/1.4 zooms and f/2.0 zooms are incredibly rare. In any case you are being mislead by the blurred background into thinking this was shot with a fast f/1.4 - f/2.0 lens. Background blur is actually more closely related to the size of ...
My settings in this situation (action in full daylight) would be 1/2500th of a second and either ISO 400/f5.6 or ISO 100/f2.8 depending on which lens I was using. 2/3 over sunny f16, but accounts for inevitable falloff wide open. 1/500th seems way too slow. There's no reason to have any exposure automation in full sunlight--get it right once and lock it in ...
It's practically impossible to tell, but as I am procrastinating I will take a shot (ho ho): Guesstimate analysis: Telephoto of a minimum 200mm - reason: It's a kite surfer. There are ways of getting this close without a tele, but they aren't exactly simple, and would mean you'd have to be very good indeed at accurate panning - imagine how fast she's going ...
This is mostly guess-work: To me this looks like a medium length zoom: (Assuming its on a Full Frame body) of 150mm - 200mm. Shutter speed would be 1/200th+ ISO 800 (I NEVER use Auto ISO) Aperture may not be that large, as the lens is long-ish, could be 3.5f ish The vignette looks fake
