I often have to zoom in to the pixel level to see any noise, even over ISO 10,000; even then, I see virtually no chromatic noise. The photo below is a 100% crop of what I took last Saturday at ISO 51000 of our older daughter's cats watching us at her house.
Yes, I have had no noise complaints from any modern Pentax since the K-7 anyway...( I just never warmed up to that sensor, though I did get some nice shots from it occasionally)
My rule of thumb is this: If it was never available as a Film ISO, then I have no right to complain about noise at that level in Digital ISO
The highest ISO film I was ever able to purchase was ISO3200... just say'in.
This is only my personal rule, I'm not saying anyone else must go by it. But... it does speak a little to how spoiled we have become with modern sensors.
Now, alternately, it almost goes hand in hand, improved high ISO almost always means better base ISO performance also, and I would always take that! I would love a new FF sensor, or APSC for that matter, that goes down to ISO50 or ISO25 too!!!
Now THAT would get me more excited than ISO1,000,000 whatever!
