I think you are way off here! Present pixel sizes are nowhere _near_ the
wavelength of light; in fact I don't think it would even be possible to
manufacture anything remotely that small with foreseeable technology.
As for the resolution needed to equal 35mm film, I think I have seen it quoted
that it would need about 8-10 Megapixels. I imagine they are talking about
mid-range print film here, such as Kodak Gold 100. Fine grain emulsions like
Kodachrome would obviously need more pixels.
