You're overstating how much the ADC is doing and also how distinct it is from the rest of the processor. The ADC matters, yes, and in past generations some of the biggest leaps in image quality and possibilities were down to advancements in ADC efficiency, but for several hardware generations now we've been at a point where the ADC is A) capable of far more than is being asked of it, and B) so refined and 'direct' in its work that it really can't have any particular image qualities attributed to it. Additionally, it has been a long time since it was normal for the A-D conversion to be handled by a physically separate unit than the main processor (I say 'main'; of course many SLRs have been made with multiple CPUs, and which one is doing the most work varies from camera to camera) and in many cases the whole imaging sequence—light capture by the sensor, conversion to digital, and processing and saving—is now handled within what is technically a single part (by patent purposes), rendering the distinction between ADC and the CPU not only irrelevant but actually inaccurate.Geek said:[words cut for space]
Analogue-digital conversion matters, but your take on it is a little out of date and even in the cases where it's not (e.g. Fuji cameras) it's still not really correctly crediting each part.
