The measured resolution on the other hand is not the simple answer it used to be in film days either, because aliasing comes into play. Strictly speaking, you should cut off your resolution measurement at the first sign of any aliasing (as results beyond this are suspect). Where that occurs is a bit subjective and if done conservatively, we would be downgrading all these cameras quite a bit...

On the other hand, MTF curves canbe objective if one compares the contrast ratio at Nyquist (0.5 cycles/px). In the curves I published above, the SD1M had a slightly better MTF at Nyquist than the Fuji. That would bode better micro-contrast but a greater susceptibility to aliasing. Seems like we can't have the one without the other

Of course micro-contrast isn't everything but, as a watch photographer, it's high on my list camera properties.
