評價:
I use this lens mostly for motorsport photos. Image quality is very good, but the micro USM is not as quick as the ring USM as fitted to the 70-200, especially in AI Servo mode, so I've missed some shots of fast moving cars approaching or driving away from me. I would recommend this lens highly if AF speed is not your major concern.
Great lens for those who cannot afford the 70-200 F4 IS.
