The new M.Zuiko Digital Ed 12‑100mm F4 IS PRO is a 24-200mm equivalent zoom for the Micro Four Thirds system. On paper, it's the ideal travel lens, and we were lucky enough to bring one back from Photokina last week to try out. 

So how does it stack up? That's what we wanted to know, so we spent a jet-lagged morning back in Seattle trying it out with the OM-D E-M1. And we have the pictures to prove it.
