When I'm shooting field sports, my favorite images are very frequently tightly cropped shots that include the subject's face and the game ball. Because these fields are generally very large and invariably, my subject is deep in them, the Canon EF 600mm f/4 L IS II USM Lens is what I'm usually using.
Tracking action with a narrow angle of view is somewhat challenging, especially when implementing the tight framing I'm referring to. When the framing is ideally-tightly cropped (in camera), it is extremely challenging to release the shutter the moment the ball enters the frame. That is where another strategy combined with the Canon EOS-1D X's 12 fps frame rate comes into play. I follow the subject in the viewfinder and watch the game through the player's eyes.
In this photo example, I knew that the opposing keeper was going to kick the ball and that my player was in position to potentially receive of that kick. I half-pressed the shutter release to begin focus-tracking in AI-Servo mode. As I watched her eyes and facial expression (sports bring out the best of these), I could tell that she was about to intercept the ball. I fully-pressed the shutter release and, along with a few before and after shots, captured 3 with-ball frames of the player's approximately .3 second interaction with the ball. One frame had the ball entering (shared here), one included the ball just after impacting her foot and the third included the ball leaving the frame in the same position it entered from. Using a wait-until-I-see-the-ball strategy to begin shooting and estimating a .2 second reaction time as being best-possible, I would have been very fortunate to get even one frame with the ball included.
This image is actually a composite of two of those frames. The image with the ideal-for-compositional-balance ball position was framed so that the ref's face was cropped at the eyes. This was no problem since I had a handful of other images captured at the same time and some had more of the ref's head included. I simply aligned one of those other images under the main image to add to add the missing details to the top of my preferred image.
Another comment I should make about this image is that it was captured under full sunlight at a terrible time of the day for lighting (1:18 PM). This lighting typically creates harsh shadows under eyebrows, creating the raccoon-eye look (see the ref's eyes for an example). Unfortunately, photographers do not usually get to schedule sporting events around their ideal photographical lighting times. You must deal with what is available. Because my player was looking upward in this photo, her face is fully lit.
