Actually if you stand back enough and use a zoom lens like 300 or 400mm you can actually 'de-focus' the fence to become a blur darken broad line and can get most of the car in full view. Of course if you can get a Grandstand highest point you can clear the fence and shoot freely. Rdg the lens f2.8 is best but i dun hv so I use 55-200 cos it's light considering you'll be standing there holding the cam and shooting for at least 2-3 hrs. 'Chew suun'
