Question:

Why does the preview appear unsmooth when changing the zoom factor on the S20 FE's rear camera?

Answer:

The ultra-wide, wide-angle, and telephoto camera lenses are positioned differently, causing a time difference similar to the human eye's left and right delay. This results in a slight angle of view difference when adjusting the lens according to the zoom factor. Additionally, switching between ultra-wide, wide-angle, and telephoto modes quickly produces an unnatural preview screen appearance due to the required transition time. To achieve a more natural preview screen, change the zoom slowly.

Wide-Angle Camera - A camera lens with a wider field of view than a standard lens

Angle of View - The extent of the scene captured by a camera lens

Preview Screen - The live display showing the image being captured by the camera
