在缺乏光线的室内环境中，如果使用高感光度如iso 800进行拍摄，那么你的相机将不再需要太多的光线。

Light is scarce indoors, and at a high sensitivity like ISO 800, your camera doesn't need as much of it.

在极端的CMOS高感光度由于传感器，在弱光下拍摄的电影，而往往是困难的一个专门的摄像机，现在可以用在EOS维马克iv实现。

Thanks to the ultra-high ISO speed of the CMOS sensor, movie shooting in low-light situations, while often difficult for a dedicated camcorder, can now be achieved with the EOS 1d Mark IV.
