Testconditions: Sony NEX 3 (FW 0.4), tripod, JPEG Fine, ISO 200, center AF area, DRO-Off. Import and export in LR4, no PP applied, no sharpening on export.
I've made center, corner and CA samples on 100% crop. See below.

Flare (clickable)
Flare was difficult to produce. No matter how I positioned the camera and lens towards the sun, this was the worst I could accomplish for now.

AF is pretty fast and very quiet. Your ears need to be very close to even hear the AF! I noticed that when you shake the lens, some element appears to be loose or floating. I think it's by design though.
It seems a very capable lens for the money (€189).
