I'm not sure my D800e would have done a much better job…
You have a scene with a wide dynamic range, harsh shadowy light, and half of your subject is in shadow. Your overall exposure is fine, your camera performed well. The possible solutions to the problem don't include a different camera, they all include altering the scene.
The solutions to the problem include: • Add light (fill flash or reflector) • Turn her more into the sun • Move her into a better lighting situation (i.e., blocking the direct sun) • Shoot earlier or later (lower dynamic range)
But this was a grab shot — you get what you can take — and the exposure is actually quite good. The solution in this case is ten seconds in Lightroom.
