AF support also requires firmware upgrade for optional LA-EA1 Lens Mount Adaptor. With an A-mount lens attached to NEX-5/NEX-3, autofocus takes approximately 2 to 7 seconds based on Sony measurement standards. Actual AF time with A- mount lens may vary depending on the subject and shooting conditions. 这个af很鸡肋啊

套头就是按照CDAF设计的。转接头不是
【在 w****n 的大作中提到】 : 我也觉得很奇怪,按道理说转接头和套头都是sam马达,都是机身一样的反差AF算法, : 那为啥转接还是比套头慢呢? : : approximately

可能驱动力要求更高,马达力矩不够所以只好转慢点
