If the cars were travelling quite fast, then the fact that some pictures
were a bit blurry (soft) could simply be an indication that the focus
was slightly off. The f/2.8 lens would have had better autofocus, so
your keeper rate might have been a bit better. However, sometimes the
aperture that you were using was quite stopped down, versus the f/5.6
that your lens is capable of at the long end. If you had shot with the
aperture wide open, then the shutter speed would have been a bit higher,
with a greater likelihood of stopping the action and minimising the
effects of camera shake.
