Do you think the image of SD14(SD15/DP1/2) is cleaner than that of SD1m(DP1m/2m) ?

I found that there are more purple and green noise in the dark area of the images of the SD1m than that of the Sd14 when both in low ISO (ISO 100). Is the noise related to the Dynamic performance or is that just little purple fringes caused by lenses?

I think SD1m should have better dynamic performance than SD14, what do you think?

I own neither camera but, in theory, I would expect "cleaner" performance from the SD14 (all other things being equal) - based solely on pixel area and therefore well capacity. Pixel pitches are 7.8um and 4.9um so the SD14 has over twice the active area.

The discussion might be muddied by versions of SPP, default noise reduction, etc.

In my view, giving in to the Marketing Grail of ever-more MP's is a retrograde step, although I do recognize that some folks like to make large prints.

The danger of more MP is partly a myth IMHO.

Sure ... if you increase the number of pixels you add to the noise level. And when you hit a certain limit, the image starts to degrade fast.

And sure ... at pixel level, you surely get a steady degradation. But ... at image level thats not important.

In practice, increasing the number of pixels increase IQ. Until you hit that limit for fast degradation.

So - where is the Merrill sensor on the scale of degradation? I dont know. But - I guess you cannot really increase the IQ by making it fewer pixels. At least not substantially. maybe you could increase high ISO performance, and maybe you also could avoid the stripes you can get if you increase contrast. But otherwise? OIt seems like the Merrill sensor is a rather nice compromise.
