Rapid Autofocus

One of the coolest aspects of the Canon 1Dx is it's ability to hold the focus on moving objects.  There are a number of presets to select from depending on the type of movement one is trying to capture; for instance rapid lateral movement like a bike race or perhaps something more methodical but multi-directional like gymnastics.  There is also one for rapid unpredictable movement in any direction.  I call it the Welsh Springer Spaniel setting.  That's my dog Banjo looking sharp at Terwillegar Park.  Canon 1Dx with Canon 70-200mm IS f2.8L lens.
