Situation: You want to know why your telephoto lens will blur first before jumping to preview.

Applicable to: Reno2.

The telephoto lens in the mobile phone has a closest focusing distance of 30cm. When the shooting distance is less than 30cm under the telephoto lens framing, it will automatically cut to the main camera for framing, and the lens will jump during the lens switching. So it will blur first and then jump into a clear one.

Additional information: Telephoto Lens allows you to photograph a subject that is far away or magnify the subject in your frame.
