Correction: it's 11 MP of luminance information, whether the input is
a colour image or B&W, and whether the output is colour or B&W.
The *only* time you won't get that luminance information is when the
subject doesn't have any luminance information, such as the red-blue
saturated colour test patterns that someone used to explore Bayer
sensors at their weakest. Fortunately, this never happens in real
images. There is always significant luminance detail.
And 11 MP of luminance is a whole lot more than the 3.4 MP maximum
luminance information from any of the Sigma cameras.
The 1Ds colour-only resolution is a factor of 2 less. But this is not
the resolution for colour images, it's the resolution for the *colour
differences* once luminance has been removed. Even for very colourful
images, luminance resolution is much more important than colour
resolution.
