Dpreview is notorious for pretending ISO differences don't exist between cameras. Vague references to T-stops and the like. 2 weeks ago, they admitted that they manipulated lighting levels to equalize camera tests. Now, they've said that comparisons of same ISO levels do not give real results when it comes to camera noise, because some camera's ISO do not match others. It's about time they finally came clean. Their take on the test of a new Fuji:

"At higher ISO settings, the X-E2 produces cleaner images than the D7100, even when compared at a common output size. However, given the longer exposure the Fujifilm requires, it's also telling to compare its performance to the D7100 set one ISO setting lower, where the difference is much smaller. It's a similar story with the EOS 70D, with more comparible results if you drop the DSLR's ISO by 1EV to more closely match the exposures."

Pressure from the gentle hand of DxO?
