This test found a lot more read noise with the A700 than even the 30D:

I don't believe what I'm seeing of Sony's in camera demosaic and
processing is particularly due to read noise.

When Joseph talked about "getting the preferential treatment from
the sensors group." he was clearly talking about the hardware, not the
demosaicing.

And except for the possible choice of different colour filters, if they use
the same sensor, they should have the same shot noise.

So it's the read noise that has scope to differ between the cameras
and seems to do that quite a lot.

Also, I'd caution people to read too much into all these isolation
tests. While they reveal some attribute of the underlying system,
that's not always relevant to the final image.

It's useful to know the quality of the raw files the camera outputs.
Read noise is absolutely central to dynamic range, a not unimportant
characteristic.
