Yeah, I know this too, Tim.
But that reddish cast was not exactly what I meant.
The problem you discibe is porbably caused by bad WB tuning.

Using the same lens will give you more accuracy as lenses vary one to
another.
Of course, you're testing just one sample of K10D against one sample
of *ist D bodies, but I thought that's what you were after.

A proper exposure test would mean, to me, using the same lens and

Jens, at al. I did not perform any tests such as this one, however my
general impression is that K10D:
