It must be the shutter vibrations that caused the background of my picture to become "blur", especially when I tried using my summilux f1.4. Very blur background, only the centre object is razor sharp.
You called that bokeh is it?
Haha...

ic, there is an article at http://www.sonyalpharumors.com/a7r-shutter-virbation-is-a-non-issue-test-by-ferrell-mccollough/
that suggest that the vibration issue seems to be overblown. Oh well, pixel peepers seems to be making a loud of noise since the days cameras can use ISO 800 and beyond.
I recall the days where Sony started the A850, it was slammed for the shutter sound and it cannot shoot low light. When the A7r is out and apparently can shoot low light very well, it was slammed for too much artifacts and compression. Haters love to hate, I guess. I dunno all these technical details, I am just a happy user to record images I see wherever I go.
