Ahh sorry, I must have had my numpty head on this morning

In my defence when using the native camera app you tap the 0.5x, 2x etc to go to that camera mode not to zoom
So what you're saying is if you're in the 24mm camera (standard camera) and click the 1x icon it will zoom to 48mm? In this instance would it still be 48mp, i.e. it uses interpolation to create 'new pixels' like the Sony Clear Image Zoom
This article is about an in-camera zoom function called Sony Clear View Zoom, which effectively doubles the magnification of your lens with little or no loss of image quality.

If so is this jpeg only or is it still a raw file?
