[QUOTE="Steve B, post: 217332, member: 15754"] My understanding of this from articles I have seen is that this is due to the way the signal is processed. Partial (or intermediate) iso values like 1250 require the A/D converter to apply digital multiplication to the signal. I am not sure how partial iso values are implemented on the D600 but it may be that the sensor is actually being exposed at 1600 and then the A/D converter is modifying the signal. Some people argue that you should avoid using intermediate iso values due to the extra signal processing applied. [/QUOTE]
