Rally is different than other forms of motorsport. Because the teams do not race on a circuit, photographers only get one chance per stage to capture the action. Once the car is past your position, they are gone, rallying on to the next stage in the event. Because of this, it is important that a camera be able to autofocus quickly and accurately.
Rally is a motorsport like no other. The action is fast and frenetic, the fans passionate, and the logistics challenging. To cover a rally as a photographer you need a camera that can keep up with the pace of the event. Rallies happen in all weather conditions, so the camera needs to be able to get the shot every time.
