Combing Artifacts at intermediate ISO's. Does it effect the 1D MarkIII?
The 30D and the 5D, at least, seem to have values in between integers of ISO, made by expansion of a neighboring existing calculation rather than am independant path.
The result is a comb appearance in the histogram for the missing values. See here !
So does this apply to the 1D flagshiop series and especially to the 1DIII?

Hi Rechard,
So I presume when you said "all ISO settings" you included intermedate 1/3 stop ones like ISO 125? If so and you did not see any combing then the 5D would certainly seem to have "proper" i.e. alanog amplifier driven intermediate ISO settings.
...unlike the 30D. Here is what an ISO 125 histogram looks like from the 30D:
The histogram looks "solid" because of the heavy combing. Here is a zoomed in section:
