The image deterioration point depends on the image size (page 62). The smaller the image size, the higher the zoom factor you can use before reaching the image deterioration point.

Though digital zoom generally causes a deterioration of image quality, some digital zoom without image deterioration is possible with image sizes of “5M (2560 × 1920 pixels)” and smaller. The range in which you can use digital zoom without image deterioration is indicated on the display. The deterioration point depends on the image size.

When shooting with “Auto Framing”, the image size is fixed at 3M (2048 × 1536 pixels) and the Undeteriorated Image Quality Range is 7X.
