View levels can be selected either "manually" or "automatically", and you can also temporarily switch off view level changes when zooming in or out.

视场等级可以手动选择也可以自动切换，还可以在缩放时临时性地关闭等级变化。

Since autofocus may not work all that well, I'll activate live view, zooming in as far as I can, then manually focus on the moon.

因为自动对焦可能不工作的很好，我将激活实时视图，据我所放大，然后手动聚焦在月球上。
