Slow speed for action

Further to the previous story Peter de Rousset-Hall has sent me this photo taken at last month's Silverstone Classic in the UK.He was obviously in a great position but even with his long lens he has had to crop the photo to give an effect equivalent to using a 2000mm lens.The interesting feature of the shot is that it was taken at 1/80th second which has just frozen the front car as it accelerates out of the corner but the cars behind are blurred.A superb action shot Peter.Well worth lugging all that gear around for.
