Not sure what all this talk is about, but the LEA2 Sigma 120-400 with PD AF is lighting quick. When I first received it however it had to send it back to Sigma (NY) for adjustment to the HSM motor as it had some issues, it came back working perfect.

I have hundreds of pix of quick focus after focus shots of fast moving subjects such as these cars at dusk, I will have to add the sequenced shots later to ilustrate but for now this is all I can show - Hand held, point camera, hold down and fire away and it just kept AF:
