This action photo required quick auto focusing which my Canon 5D MkIII is very good at. I made sure my shutter speed was high enough to freeze the motion of the dog jumping at 1/800th of a second. I set my focus to AI Servo mode to keep the dog in focus as he moves. As the dog was getting ready to jump I held down the shutter button and followed the dog jumping. My camera with the Canon 24-105mm lens was able to get every single shot in focus and I choose this photo as the best from the burst series.
