ok. I got a call from the shop. They checked my issue with Sony and they received an answer: This sound is normal in AF mode. For video shooters, it should be silent enough in manual focus mode.
So, it looks like I just got a copy that is louder than others (Roger Cicala (DPR) pointed on some variations in loudness while testing 40 of it). I will go now and pick up my copy, and see, if I get it more silent through use (as some pointed on, it is getting more silent through use).
As I made already some tests to check image quality, I will keep it anyway. It is just too magic to ignore (to combine Lucille and Guy to one sentence. ). And my copy is perfectly centered and sharp. If there would be an issue later with scratches, oil, flakes or whatever, they have to replace it anyway (thanks to guarantee). So there is no big risk for me at all.

Thank you. The lens is back in the store and they check it with Sony.
The good thing is, that the shop owner looked puzzled as well, when he heared the sound. The bad thing is, their own copy sounded the same.
I asked for some user feedback at dpreview and some reported the lens is as silent and fast as the 55/1.8. One found a link from a chinese site, where there were scratches from the mechanic on the lens and the same sound. So it looks like I received a bad production batch.
Beside that, I made some tests yesterday:
- It looks like the lens is as sharp (or even sharper) as the 90/2.8 macro over the whole pic at f5.6. At f1.4 it's decently sharp. Nothing that would be noticeable, with that small DOF. Those crazy MTF charts seems to be reality.
- The bokeh is cream dream. I couldn't recognize a hint of an onion ring. The blurred background does not deform toward the corners. The switch between sharp area and bokeh feels very constant.
- The special cover to reduce flares is scary. If you have a led lamp in the center, it looks like turned off, even it is turned on. I didn't test much on this.
- HEAVY! The 90/2.8 feels good, but the 85/1.4 is just a brick on the front. I think, it can be a pain, to use it over several hours. I'm thinking of a vertical grip, just because of that.
