As one who has taken their share of noisy pictures and had to put up with it on my old camera, I say that this sounds quite nice. However, if "noise" is just "sporadic, brightly colored pixels caused by shooting at high ISOs", why would one even need an on-off switch for noise reduction? What's the trade-off? Like, if I found out that my new Porsche 911 turbo came equipped with a switch that said, "Flip switch to activate Car-Won't-Crash mode" I would wonder, why wouldn't this just come standard? So yeah, why is there even a choice between more noise or less noise?
