thought testing DR is a bit complicated and i don´t know if their methode is convincing.
This might not really be the ideal place to discuss this deutsches gearhead-centric review, but the dr range on the 6d is a big letdown if it's true what they discovered. Why do you think their simple approach with a greyscale chart isn't convincing?
Other than that the sharpness difference 5d2>5d3>6d might not matter much in real life, but it confirms that Canon has modified the tradeoff less noise/banding for less sharpness.
