    Super sharp5.0/5

    Super sharp Getting great results with this lens and my OM-D EM1X. Even with the MC-14 teleconverter (must be in MF mode, though. Auto focus modes just can’t seem to get there at 400mm)!

    Sharp, well made lens5.0/5

    Sharp, well made lens I previously was using a Panasonic/Leica 100-400mm lens, which I sold to fund purchase of this Olympus lens. Although this lens is slightly larger and heavier than the Panasonic lens, it is a bit sharper wide open at full zoom, and it has a much smoother zoom ring action.

    A must for Olympus sports and wildlife shooters 5.0/5

    A must for Olympus sports and wildlife shooters This is an amazing lens. It is incredibly stable and you are able to take shots of static subjects with a shutter speed of near 1 second at 400mm. I’m very impressed with it and purchasing it used made it a great value.
