So with the D5, it can boost its ISO to ISO 3,280,000, and suddenly how ISO is named is becoming just stupid. We should use EV steps instead:

ISO 50 : ISO EV-1 ISO 100 : ISO EV 0 ISO 200 : ISO EV+1 ISO 400 : ISO EV+2 ISO 800 : ISO EV+3 ISO 1,600 : ISO EV+4 ISO 3,200 : ISO EV+5 ISO 6,400 : ISO EV+6 ISO 12,800 : ISO EV+7 ISO 25,600 : ISO EV+8 ISO 51,200 : ISO EV+9 ISO 102,400 : ISO EV+10 ISO 204,800 : ISO EV+11 ISO 409,600 : ISO EV+12 ISO 819,200 : ISO EV+13 ISO 1,638,400 : ISO EV+14 ISO 3,276,800 : ISO EV+15

That would put more normal values to these numbers. The Hi5 setting of the D5 sounds unbelievably high, which of course it also is, but it's "only" twice as "sensitive" as ISO 12,800, but the way ISO is named makes it look stupid as fuck.

And, when talking about ISO, you'd just say "it was shot at ISO 3" instead of ISO 800.

And the new D5 would have a max ISO value of "ISO EV+10" which can be pushed in-camera to "ISO EV+15", which would still be equally impressive.

Right, even old German DIN scale would be much more convenient for higher sensitivities.

ISO is really ASA°ISO, i e ASA100 is DIN21 or ISO 100°21...

Forgot:ASA is American Standard Association and DIN Deutche Industri Norm . ISO 50 : DIN 18 ISO 100 : DIN 21 ISO 200 : DIN 24 ISO 400 : DIN 27 ISO 800 : DIN 30 ISO 1,600 : DIN 33 ISO 3,200 : DIN 36 ISO 6,400 : DIN 39 ISO 12,800 : DIN 42 ISO 25,600 : DIN 45 ISO 51,200 : DIN 48 ISO 102,400 : DIN 51 ISO 204,800 : DIN 54 ISO 409,600 : DIN 57 ISO 819,200 : DIN 60 ISO 1,638,400 : DIN 63 ISO 3,276,800 : DIN 66
