Hi all,

I recently purchased the 5Ds and love it. However i'm having trouble with autotracking subjects. I went to a bird show and when the birds were on the handler's hands it was fine, but when it took to flight to the other handler the bird became a big blur and out of focus. I was shooting at 1/2000s so I know it wasn't shutter speed.

How do I correctly track subjects? I had the impression I'd see the focus point follow the bird but this didn't happen at all
