real ISO about ISO 40000

I would say the max. real ISO on the MK4 is about 40'000 instead of the mentioned 102'400.

if you compare and use this measurement below:

From http://www.dxomark.com/
compare and select a brand, cam and so on

5D MII; ISO 100 = real ISO 73
D3x; ISO 100 = real ISO 78

5D MII; ISO 200 = real ISO 143
D3x; ISO 200 = real ISO 170
D3; ISO 200 = real ISO 161

5D MII; ISO 1600 = real ISO 1093
D3x; ISO 1600 = real ISO 1369
D3; ISO 1600 = real ISO 1275

5D MII; ISO 6400 = real ISO 3990
D3x; ISO 6400 = real ISO 5015
D3; ISO 6400 = real ISO 4790

5D MII; ISO 12800 = real ISO 7555
D3 ; ISO 12800 = real ISO 9566

ISO 25600 = real ISO 15'000
