What is the sensor size of your mobile as compared to full frame DSLR?
The sensor size of a full-frame DSLR is 36mm X 24mm i.e. 864sq.mm. Whereas, the sensor size in mobile phones diagonally measuring 1/2.5″ is 5.76mm X 4.29mm i.e. 21.71sq.mm. Thus we can see a major amount of difference in the sensor sizes which in turn affects the image-detail-capturing ability of the camera.
