Any image of a moving subject will require a high shutter speed to avoid blurring of the subject. The kite surfer above was moving very fast and required good long lens technique and a very high shutter speed to avoid movement of the subject.
When long lenses are used, high shutter speeds will also be required to avoid camera shake which becomes difficult to avoid. For subjects such as this a shutter speed in excess of 1/1000 of a second would be required. In order to acheive high shutter speeds requires the use of high ISO and also large apertures.
Many modern cameras will offer fast shutter speeds of up to 1/8,000 second and this will give a great advantage in capturing fast moving subjects.
