Nokia Puts 41MPixel Camera In a (Symbian) Phone

judgecorp writes "We aren't sure what's the strangest thing about Nokia's new offering, the fact that it's got a 41 Megapixel camera or the fact that it runs Symbian. It has a very high resolution sensor and uses oversampling, apparently producing good results in low light. Users can either save a maximum of 38Mpixels, or else zoom and crop for normal resolution images. Observers expected a maximum of one more Symbian phone before Nokia shifts over to Windows Phone. This suggests either a longer life for Symbian — or maybe [that] Symbian was just an easier platform to make a show-stopping device that may turn out to be more of a concept phone."

Diffraction limited?

[ControlFreal]

Your average phone has a ~4 mm (diameter) lens. This yields an Airy disc of some 1.15 minutes of arc.

Even at a wide field of view (say, 60 degrees), this yields a maximum lateral resolution of some 3200 pixels. Isn't thus any camera with more than ~10 MPixels diffraction limited by the tiny lens, and not sensor limited?
