Olympus has announced a new zoom lens that would be great for travel photographers or anyone who wants to cover a wide range of focal lengths with just one lens. The M.Zuiko ED 12-200 f/3.5-6.3 zoom weighs just one pound and covers an EFL of 24-400mm (16.6x) and has the largest zoom range of any mirrorless, interchangeable lens. But it’s not a cheap piece of glass. This new lens is made like a tank with weatherproof construction.
