I didn't mean to put words in your mouth. I was just disappointed
that you went to the trouble to do this comparison that I find
uninteresting. If you have done the same comparison as this one but
at maximum ISO gain then I would very much like to see it. Can I
trouble you to link to it one more time? I do appreciate the effort
you make to do these comparisons (I don't have an FZ50 so I can't do
these tests myself) but I was frustrated that they didn't show the
sensor performance comparisons that I think are important. My post
above came out more disparaging then I intended, I just meant to
explain why I think maximum ISO noise performance is most important
for comparing sensors with different size pixels.

I think this may be what you're looking for:

moreover, it's the test that you and I think is more appropriate (at ISO 1600). The only drawback is that the 10D read noise is about 9 electrons, about a stop worse than the best current models which are around 4 electrons. So imagine the 10D image with half the noise...
