This is totally bogus.
First thing, the lens is not doing anything to the Megapixel. Anyway the CarlZeiss lens is already pretty good.

Second, if you want more Megapixels, you need a larger CCD, otherwise you have more Megapixels but smaller pixel size,i.e. less signal to noise ratio. In addition, it doesnt make any sense to have pixels, smaller than the diffraction limit of the lense.

Third, how would you replace the CCD???? Come on, by a Canon powershot for a 100bucks and you are fine.
