However, the pixel density of the film can be straightforwardly reduced by fabricating smaller array spacing and a smaller antenna size, as well as using a more tightly focusing lens for recording.
但是，薄膜的像素密度会由于通造更小的阵列间距和更小的晶须尺寸以及使用更精密的聚焦透镜等直接降低。

It has an extremely fast and almost silent focusing system, which makes it an ideal lens for video recording as well.
