Default $230 12MP camera?

And if it's a non-slr camera (which at $230 it would have to be), the
tiny sensors don't really resolve at the full 12MP anyway. Very
likely that there'll be no discernable difference between a similar
6MP and the 12MP models. On compact cameras, Megapixels is now just
a marketing wank, and no real indication of image quality.

The camera model referenced has a sensel size of 1.9
microns. The airy disk diameter at widest aperture (f2.8 at
minimum focal length) is double that at 3.8 microns.
It only goes downhill as focal length is increased or
aperture size is reduced.

That's even before noise and the effect of noise reduction
on resolution is considered.


Which does mean that the need for an anti-alias filter is reduced....
