I ran a few test sequences this weekend with the v3 and d800e of the kids playing dodgeball and the dog playing football. Fast moving and erratic. The v3 with the 18.5 hitrate is wayyyyy above the d800e. In fact in some sequences, at 20fps, not only were there more shots in focus, but even when the first dew shots are out, the camera adjusts and the next 20 are bang on. Some of this is due to the dof obviously...alot more room for error but I tell you, the 1 system AF in good light outperforms the d800e.Regarding the focus comment above, not being able to get focus on the RCs with the D800 is not an equipment problem. It's that frame of reference thing again
Couple of cute kids there.
