So, now it has come. Easy, wobble-free sitting, slightly heavier than normal zoom ring (which is, yes, but still to give and I prefer, as if he "baggy" would be), backlash-free focus ring. Imaging performance, as it is written by all here, very good, as long as I can tell at first 10 shots.
But a question mark remains: That it is louder than the 14-42er, was already mentioned here. But it is normal that there are these "robotic" (although slight, yet clearly audible) sounds when focusing? Is that with you so ???
