500mm Soccer Action Picture

The Canon EF 500mm f/4 L IS II USM Lens is an excellent choice for soccer photography with a full frame DSLR. Aside from having spectacular image quality, this lens' AF system has no trouble keeping up with the fast-moving action of this sport.
 
Unfortunately, sporting events are not usually scheduled around a photographer's time-of-the-day lighting preferences. I strongly prefer bright cloudy days to direct sunlight when shooting action in the middle of the afternoon - as exampled in this picture.
