Maybe a curved sensor could eliminate the need for distortion correction in these compact cameras. The downside is I can see where cost of manufacture would be much higher because each one has to be individually bent. We may not see these sensors until ways to mass produce them is devised.

I see two major problems with it:

  1. It needs to have a spherical (like an eye-ball), not a cylindrical, surface to work properly. This double-curved surface will not be easy to mass produce, as you can't just bend a flat sensor as described in the article. It might have to be moulded, not bent, into shape.

In that case costs would be prohibitive.

  1. It will only work with a fixed focal length (ie, prime) lens, not a zoom lens (eye-balls don't have zoom lenses). So it would be great for a future RX1, but hopeless for a future RX10. More probably, it would be used in high end phone cameras, which typically have multiple fast prime lenses.

Yes it would work optimally at only one focal length but maybe it would require less correction at other focal lengths than with a flat sensor.

People who don't understand the engineering and manufacturing problems involved often jump the gun with their enthusiasm. That doesn't mean that it won't happen someday, just not soon. We'll have to see. Maybe Sony has already worked out the problems.
