They didn't have the same, the one in the A900/850 only went down to 0EV.
Tried the Pentax K5IIs? It shoots right down to -3EV and 7 FPS. Try confronting it with a crawling infant, in broad daylight, and it gets totally lost ..............so much for state of the art (shoot in the dark) AF systems......... Just leave the action to the Big boys of Canikon. They always get the job done.
