这款照相机集经久可靠性、无与伦比的光学性能和速度于一身。

The camera combines rugged reliability with unequalled optical performance and speed.

这张鬼异的照片并不像光学照相机那样，它并没有显示光线照到空间站表面时的反射。事实上，雷达偏转波束根本没法侦测到空间站的外表。

This ghostly image does not show light reflecting from the surfaces of the space station like an optical photograph.

他们是有一个小型的感应器，但闪光功能过于孱弱（也可以说根本没有）。长此以往，你便渐渐忘了真正照相机是拥有强大光学变焦或防抖技术的。

They have tiny image sensors but feeble (or nonexistent) flashes, and you can forget about "real" camera features like powerful optical zoom lenses or image-stabilization systems.
