A7II hands-on by Pulitzer winner Brian Smith (Camera has better High ISO and better heat dissipation).

Reminder: A7II now in Stock at Amazon, Adorama, Bhphoto and Sony US and Digitalrev.

Brian Smith (Click here) wrote a detailed hands-on of the new A7II. He confirms that some third party lenses will get the 3 and not 5 axis stabilization:

Other lenses will receive 3-axis IS from the camera IBIS – but even 3-axis is one axis more than what’s available with almost any other image stabilization system. Lens-based image stabilization only controls Pitch and Yaw (with one exception – Canon’s “Hybrid IS” in their 100mm macro). With this exception (at least for now), Sony and Olympus 5-axis IBIS are the only IS systems that offer X/Y or Roll compensation.

Another yet untold detail is that one:

The 5-Axis Sensor-Shift Stabilization mechanism also moves a magnesium-alloy heat sink that’s attached behind the sensor. This helps dissipate heat when shooting long video clips of long continuous still bursts.

Also no more “Phantom ISO changes”:

A relatively small change – but a good one – is that the control wheel no longer adjusts ISO without first selecting activating that control.

and:

ony A7II uses the same 24.3mp sensor used in A7 but it with different image processing that promises better high-ISO noise reduction for in-camera jpegs.

One more hands-on at ChipChick and noise test at Focus Numerique.
