"In the case of the Nokia 808 PureView smartphone, it’s probably best we set aside our preconceived ideas about how a digital camera should work. Nokia’s PureView pixel oversampling technology is out-of-the-box thinking and has a lot of potential for both camera phones and traditional digital cameras. Although the 808 has a 41-megapixel sensor that can capture a 38-megapixel image, in auto mode it takes 5-megapixel pictures combining the data from 7 pixels into one “superpixel.” This is sort of reverse HDR, if you will. In the Engadget video below, the Nokia rep says the combined data from one of these superpixels is comparable to that of a 7-micron pixel. That’s larger than the 6.5-micron pixels in Canon’s just-announced EOS 5D Mark III full frame digital SLR. In other words, that’s a big “effective” pixel. That’s not to say the Nokia 808 PureView smartphone is going to have better image quality than a professional digital SLR like the 5D Mark III. The sensor is just one piece of the camera equation. But the pixel size comparison does help put things in perspective."

Sounds like marketing gobbledygook. Whatever the 1/1.2 inch sensor can do, it's only as good as the lens in front of it.

I like my phone cam, but to be honest it has 8 Megapixels worth of overkill. A pinhead-sized lens mated to a tiny sensor is fine but I get the same quality at the 1.5 Megapixel setting.

But the MP rating helps sell so many more phones!

Believe it or not, there's a Schneider screw-in lens for the iPhone. I saw it yesterday.

This sensor and the lens build in a film scanner would be nice! The Backlight should be dimmable for "HDR-scanning"

With the small diameter lenses usually found on these phones, there is no way it can equal the resolution of a much larger diameter camera lens. Physics tells us that the diameter has a large affect on resolution. Even if the two lenses were equally corrected for aberrations, there would be no contest between the two.
