Olympus mZD 12-50 f3.5-6.3
This is the new kit lens that came out with the new OM-D EM-5 camera. It matches the OMD in being water / splash proof. I haven't tried it myself but I'm sure I'll find out when I'm out on a wet walk. From what I've seen already it's not such a bad lens. A bit slow at the long end but I will be using this lens when there is good light so that won't bother me at all. It is not meant as a low light lens and I don't think any sane person will try it out for that purpose.
