Originally posted by illdefined Westmil, plenty of cameras do this, including the K-5 when you turn on "Highlight Correction". it halves the ISO then bumps up the curve.
Ever notice you can't get to ISO 80 when you turn "highlight correction" on? It's something the excellent DR of these new Sony sensors allow.
Of course they do, Im well aware of the fact. This has nothing to do with highlight correction being set. It is the amount it is out... not the fact that it is out. When it was measured for ISO accuracy at 1600 ISO it was found to be in the region of 775 ISO. Thats not out, thats simply a lie lol.
Thats simply a huge innacureacy ! As you say none are that accurate but this is at best, rather missleading. So much so that I think it has to be deliberate. Thats just my opinion of course but that is exactly how it appears to me.
