Sometimes in life things happen fast and you need to get that one shot of something moving. These two are often found chasing each other.
What I tend to do is to put my shot selection to high speed continuous shooting so that I can rattle off a few shots. Also, I select on my Canon AL SERVO - or Nikon (AL-C). This autofocus mode is useful for tracking moving subjects and for focusing at very shallow depth of field (wide apertures) when shooting hand-held in very close-up situations.
The question is does Jasper ever catch Kaya?
What are you going to catch today?
