The zombie wedding is great. Nice shallow focus, engaging tones.
I wanted to put the Nikon's AF through its paces today, so I went with a friend to go play with his dogs in a park. The dogs used to be racing Greyhounds, so it was definitely a challenge to track them -- for me and for the AF. Still, for a first attempt at this kind of thing with the new cam, I'm quite impressed with its performance. I took Ken Rockwell's suggestion and used AF-C in 3d mode:
Generating Enthusiasm
Unrestrained
Velcro
Off Lead
It took a while to get them really riled up and running in the directions we wanted them to, but once they were going, boy were they fast. My friend is in the first photo, holding my K-5 with the DA*300. I'll have to take a look later to see what he got on the Pentax.
