Okay, that makes sense. However, these were field shots at a soccer game under lights and ISO 25,600 is so grainy and noisy that when you apply sufficient NR, the faces and soccer ball are blurry, which I cannot have. That's why I was saying in this case that the photos were unusable. I suppose when you have more, even lighting it is different. The shadows are actually really, really bad. I think the problem is that this "ISO advantage" is based more upon specs and even lit situations, vs. real-life harsh situations.
