Today I was reading SAR about the new curved sensor technology Sony is announcing. This technology was suggested during a thread about how to improve lens performance I participated in last year either here or on the Sigma forum. Curved sensor has the potential to vastly improve lens edge performance and light gathering capabilities as well as making faster lenses relatively smaller. At the time we thought it would not be possible. It should really help with the short registration cameras. Ricoh uses a lot of Sony sensors so this could be quite a development.

Curved sensors needs no suggestions from any forum site.

Curved film have been used in many cheap cameras, e.g. the Holga.

It is much easier to make a lens if you have the freedom to bend the film/sensor plane.

Telescopes also have it.

Now, of course, if you have exchangeable lenses or zoom lenses, the curved detector plane is questionable. Which curvature to choose? All have to have the same. You are back to the limitations of flat sensor plane.

Unless the sensor curve was not fixed. If it was bendable like flexible LCD displays...the lens manufacturer could transmit data to the camera to tell it how much to curve, or even asymmetrically curve the sensor to produce the best image. This could allow lens manufacturer's to customize the curve to fit the inadequacies of their own lenses or possibly allow for micro-adjustments by the user to fix sample variation within lenses. It would also allow good lenses that already produce a flat image plane to not be ruined by a curved sensor.

Negatively though, it would also introduce more moving parts and more failure points. It might result in a larger sensor area/mirror box as well, but maybe not enough to be significant.
