As you know by end of June Olympus will release the new Olympus 14-150mm f/4.0-5.6 lens (preorder on amazon for $599).
Inside the forum photofan.jp there is one of those lucky guys that had the chance to test the new lens (google english translation). He says that focus speed is fast and very quiet. The lens it selft is very lightweight, zoom ring is very large and focus ring is very smooth.
