I can't afford that Canon 800mm they still haven't released
So I might get the 500mm (so I can carry it!) and 1.4x to go with the 2x.
But if the car filled the frame there's be no spray behind and no reflection.
I wouldn't have shot this tight even if I could have done.
I think it's fine - I like seeing more of the scene with the drab, wet surroundings contrasting against the brightly colored car and the fire. Now if I were making a poster, sure, I'd want it tighter on the car.
