First impression on the A6000 and FE 28mm f2, the combo is very fast, like really really fast, i click the back button focus and it lock focus instantly ! That might be the lens (internal focus) or both body+lens, so the Sony AF speed is exactly as advertised, the face tracking is very good if there is 1 face in the frame (more faces will confuse the camera and it will focus on the bigger face
).
That's the good, now the bad, as many already mentioned, the menu is horrible, the control is less than optimal and the grip is so small and slippery (i could drop the camera any moment if i hold it with one hand), and the AF speed doesn't translate to accuracy when using at f2 (i usually use the widest aperture for portrait shots) and eye-AF is not always there (if the person is not directly facing the camera), eye-AF also takes more time to lock focus (way slower than face tracking !)
The IQ is ok for me, color is good, exposure is good (tend to over-expose a tiny bit but nothing to complaint about), sharpness is good if focus correctly.
That's the first impression, i'll play with it a little more before making any conclusion
