how do you know waht someone else determines "useable"
And yes in practical terms 400,000 will be noisy but it raises the nar and lower ISOs will be better than cameras with a lower high ISO limit.
You could say the ISO51200 of the K-5 isn't usable by the same logic, but i the Sony si 2 stops better DR than the K-5 then I think it's a great .

Oh dear.

Originally posted by carrrlangas I don´t understand why would an enthusiast or Professional use ISO values that are not achieved by hardware. Most Sensors native range goes from ISO100 to ISO1600 (through hardware amplification), after that it´s all software amplified. If shooting RAW, as most enthusiast and professionals, why would I let the camera do the post processing for higher than native ISO values rather than do it in my workflow as the rest of adjustments?
What I get out of the big numbers is that the Dynamic range will be better at high (native) ISO (as in ISO 400 - 800 - 1600)
Why don't you ask them?
Besides hardware amplification OR software amplification it's STILL amplification. It's likely that hardware amplification above a certain gain value is better quality than the equivalent hardware ( analogue ) amplifiviation.
.... as an enthusiast I can answer you question, and the answer is I don't want to have to mess around exposure compensating to do the ISO gain in post processing when doing it in camera is just as good. Why complicate photography when there is no need?

What happened there? All my posts merged into one. how strange. I didn't use any multiple quote feature
