测光的时候，是使用Elinchrom Skyport无线电引闪器触发闪光灯。
When I measured the light I used the Elinchrom Skyport radio transmitter to test trigger the lightning.
另外，使用支持e - TTL II的相机时，闪光的测光不再与当前对焦点联动-这降低了锁焦和重新构图时发生曝光错误的机会。
Furthermore, with E-TTL II cameras, flash metering is no longer linked to the AF point you're using - this reduces exposure errors if you prefer to lock focus and re-compose.
