What exactly is a stop improvement in ISO?

[pedro]

This is some of the reason I don't like the Dxo tests. As it states that the 5d2 is better at noise then athe mk4. Now, if you have tried these cameras you know it's completely wrong. On one hand...

Between 100-800 the 5d kills the mk4... But from 1600 and up the mk4 demolishes the 5d2. So seeing that the 5d shows noise at 1320 something and the mk4 is 1260 or whatever is just to take it way out of contex.....

Very valid question from the OP. And there is different answers...

I think Canon states two stops as being able to shoot at twice and four times the iso. And they claim the same noise at the highest setting being better than two stops down on the 5d2, which could easily be true.

Now take Lightroom in to the equation, Lr3 and the 5d2 vs the 5d3 with Lr4 gives you easily three stops, so "only for jpeg" two stops is only valid with the DPP software...

Yes I am drawing my own conclusions here, and claiming stuff, because it's friday and I'm enjoying a few beers, cheers everybody! Have a good one!

Hope you enjoyed your friday...;-)

Woops!! MY bad, it's saturday, ;D

I will be foundling the 5d3 tomorrow, I hope it will give me the definite answer and reason to get the 1d X. But I got to admit, the 5d3 looks pretty awesome for half the price...
