I was switching between Olympus and Canon in last 10+ years, had a 10D and
40D and now using a 5D II, I'm always not happy about their color
reproduction. In most cases the images from Olympus was always better but I
was never able to tell the exact different between the two. As most people
say this may be just personal preference.
Recently, I was scanning some old faded negatives, the Epson 4870 was ok but
I still wanted to see how the 5D II copy compare. For a quick test I used
the Cabin CL-5000P light panel as light source for 5D II (I usually use
flash). The image's color was terrible, I was never able to get it adjusted
to give a usable image. Then I tried the Olympus E-PL1 (same light source),
it was much better but still not as good as the 4870 scan. After a couple of
days' evaluation, I found the R and B channel of the image from 5D II were
much poorer than the Olympus one. The red channel gives totally wrong
interpertation of levels and the blue channel is too thin to give proper
tonal details, only the green channel is comparable. It was really a shock
to me.
I then switched to flash as light source, the result was better but Canon is
still lag behind and the red from Canon is still wrong, it is a mystery
here.
It looks like Canon has problem on interpretation of thin tonal range
objects, in this case is negatives film and it may extend to lady's facial
details and distant landscapes.
Here are the samples, straight out from Canon DPP and Olympus Viewer,

Mostly E-3 and 14-54, some with 50-200 and a few taken with an EOS5D plus
Zuiko 50/1.4 or 85/2. For some reason, the 5D seemed to have more
trouble
than the E-3 with the blue LED light here.
Colored LED stage lighting is a pure disaster for pretty much every
Canon sensor. Sony has done something to tame them a little more. I
suspect that there is some secret sauce in the sensor or processing
chipset that does a narrowband notch filtering at the three primary
colors LEDs use.
I'm using the term "pure disaster" loosely. I'm sure 300 million Canon
users would disagree with my assessment, but that's because they are
either willfully ignorant or have never seen a comparative result from
another camera or from film.
