In the two pictures of the woman, I think that the focus is VERY slightly off (hard to get it right with such a thin DOF and low-light). It's possibly backfocussing slightly..

Yes, the focus did seem a bit off to me too when I got back to Atlanta and loaded the pictures on my iMac (Lightroom 4).  To be fair to the Sigma:  There were a couple of things working against sharpness:

  • I'd accidentally flicked off Raw capture when trying to fiddle around with micro-adjust.  I've noticed the jpeg's from my 5DMKii are nowhere near as sharp as raw.
  • I only had my iPad mini with me on the trip.....so very difficult to precisely micro-adjust this lens....I didn't seem to nail the micro-adjust and the lens needed it (ie it was soft at zero micro adjust).
