Time for the Megapixel Wars to End?

I have owned a large number of digital cameras, all the way from when 640 x 480 was state of the art to a new 12 megapixel Canon camera that I picked up to shoot a wedding in the Spring. And something has become obvious as megapixels have multiplied like rabbits - the number of megapixels in a camera has very little to do with the quality of pictures you get. It is not just that we've exceeded the human eye, but rather that after a point the expanding number of megapixels simply shows up the flaws in the lens. Consumer Reports has noticed the same thing and is finally calling for an end to the magapixel race.

The problem isn't the sensor. It's the glass. Writer Ray Maxwell points out that lenses will at some point reach a limit and that simply adding more pixels to a sensor will not result in more detail or better images. So, while and laptop and desktop computers may continue to follow Moore's Law, cameras with glass lenses will not. And that limitation is why the writer ends the article with "If someone produces a 35mm full frame camera with 100 Megapixels, beware. Given the limitations of the wavelength of light, no lens can live up to that resolution."

We're already seeing this transformation in the computer industry, which used to focus on CPU speed. Now, they are shifting to multiple threads, power efficiency, and other measures of excellence.
