Worthy successor and finally competitive

I have my original highly appreciated, but for the time being overhauled, AF 85 / 1.4D replaced with the AF-S 85 / 1.4.
The successors lived up to expectations with respect. Picture quality full and provides a much better performance especially open and a strongly increased resolution.
The ultrasonic motor has not completely met my expectations / hopes. He is very quiet and has to be very nice and focused manually, but is surprisingly slow (eg, compared to the 24-70 or 70-200).

Conclusion:
+ State-of-the-art optics, better than Leica, and also open fully usable
+ Greatly improved margin performance
+ Extremely high resolution
+ Excellent workmanship
+ Very stable and amazingly lightweight magnesium housing

- Autofocus bit slow (compared with, for example, the AF-S 24-70 / 2.8)
