Olympus M. Zuiko Digital 40-150mm f4 PRO ac adapter The Tenba Messenger DNA 15The Olympus M. Zuiko Digital 40 150mm f4 PRO is a relatively compact telephoto zoom lens from Olympus' premium PRO line. It's substantially smaller than the f2. 8 version (only about 10cm collapsed) and only loses one stop, which is not too bad! In excellent condition, with clean glass and good function. Includes hood.
