The Olympus M.Zuiko Digital 100-400mm f5-6.3 is a very long telephoto lens for Micro Four Thirds cameras: the “full frame” equivalent of 200-800mm. It features an effective image stabilizer, fast autofocus, and solid construction. The tripod foot even has a built-in Arca profile, which is nice. Excellent cosmetic condition, with minor wear from light use and handling; clean glass, good function. Includes original hood and box.
