Sigma的好像跑焦厉害。。。
"The big problem, as I already indicated, is that the lens does not focus accurately, consistently. Accurate focusing is especially important when shooting with the shallow DOF this lens is capable of. My experience with AI Servo focusing was even worse with a very low keeper rate for even moderately fast moving subjects. Over-shooting a scene gave me the one-shot AF results I wanted on most occasions. "
