Take a look at the raw DR. There will be a huge difference in comparison. There is a large ability to bring up the shadows of the D700, as well as more ability to bring back the highlights.

I own the E-3, and I'm happy as can be with it, but I'm not going to pretend the DR is in the same ballpark as the D700. The E-3 is great in good light. The D700 will eat it alive in very low or very harsh light.

What about Image-Resource?
You may have your reason to disagree with the way DXO mark the "DXOSensor" and rank without comparing corner quality, but what's wrong with DXO ranking Dynamic Range?

The link you gave me...
One person tested something on the forum that even E3 users aren't agreed with!block

Truth is, I compare D700/D90 and E3 in the shot side by side on 30" LCD on a Mac in the store.
E3 is noisy in the dark area.
Now, even if you have any way to prove E3 has a greater DR in a low quality image. (Which I still don't find it anywhere "except" Olympus user from places like forum or their own blog.)
Those noisy are still not acceptable in the printed material!

It takes me A WEEK to get rid of the noise in E1 photo for magazine use.
I don't care how many details E1 has got in dark area, if you want to get rid of the noise, you are gonna erase the detail as well!

If everyone agrees on everything we talked about here, what's the point of having the discussion in the first place.

The DXO Sensor doesn't provide information on how it ranks the dynamic range, or even anything! It's not a valid test if it doesn't provide any information on how they test it. If you are happy with a test without any background information/methodology, I'm sure you are just happy with the result of the test, not the validity of it.

Each uniform zone on the chart (a “patch”) is measured for luminance (cd/m2) with a certified luminance-meter; then all the values are input into DxO Analyzer software.
Once the target is measured and the DxO Analyzer software is calibrated, the selected camera shoots an image of the noise target at different ISO settings, and the noise for each color channel of the target image (R, Gr, Gb, B) is then measured. The mean gray level and noise values are computed for each patch and for all images shot at different ISO settings. These numerical values are interpolated for all gray levels to calculate and plot SNR curves, from which DxO Analyzer extracts the SNR 18%, the dynamic range, and the tonal range.

The link I gave you explains a different point of view. 4/3 does better in dynamic range when there is enough light. We have a lot of users talks about it even in this thread. Your experience with E1/E3 may be bad. There are, however, a lot of Olympus Users are happy with their camera to do magazine work.

You are wrong.
It said it in their website of how it ranks the dynamic range!
It is a valid test, but you just ignore everything.
Instead, you trust some guy who doesn't provide much of the information on the forum.
And you blame me trusting DXO?
DXO provide significantly more information on how they test the tonal range and dynamic range than DPReview...
