The super crisp images that we see from smartphones are largely due to the software in the camera. Traditional cameras would focus light on a photo element. The photographer would activate a shutter and whatever hit the photo element would be the picture.
The smartphones are sampling images over time and making micro adjustments to the focal length. They then stitch together a crisper image.
One might see image quality improve or deteriorate with software updates.
I worry about smartphones because smartphone companies build in planned obsolescence. I thought about getting a new smartphone, but decided that I did not trust the manufacturers.
