> The camera uses accelerometers to measure how much the camera angle changes
> and adjusts for the difference in the arc where the sharpest plane is. Then
> it compensates for errors in the field flatness of the individual lens and
> some systems can predict if the subject is moving too. Then the camera
> corrects out other optical errors. I explained that Leica M's have no auto
> focus systems or accelerometers or predictive systems at all
>
> Sam listened with interest since he enjoys technology and science. After
> all of that Sam said, "how come Ted can just point his camera, without even
> looking sometimes and get great shots?"

> Jeesh!.
