So .... then we are back to the pre Merrill color look. Flower photos with strangely colored and desaturated greens. That is a property for the sensor found in all the pre Merrill DP cameras and SD14 and SD15.

I don't know where this comes from. The SD15 is (in general) known for very good color.

Yes it is - in particular compared to SD14.

But - IMHO - the sensors that are found in the SD14 to SD15 generation of cameras has a hard time handling flower pictures. If you choose to get the petal colors correct, then the green is often desaturated and a strange color. Just look at this image. No green greens there.

don't recall having any problems with greens using the SD10:

SD10 + 70mm macro

The main issue for me was the highlight clipping and relatively low resolution for bigger prints.
I wish my SD1 could produce this result (without photoshop) in such situations:

ISO400, auto WB

One of the main disadvantages of Merrill and Quattro is noise. The two lower RAW channels are very noisy. Something you have to correct when doing color conversion. But ... there is a limit to what you can do.

We in Kalpanika have, just as Sigma, managed to tame the noise in Merrill and Quattro. But, it did take some rather exotic noise reduction of the two lower layers before doing the conversion.
