Summary: Great option for the Panasonic GH3/micro 4/3. This is a great walk-around lens. I use this with a micro 4/3'rds adapter on the GH3 (generic adapter was $59 online). Auto-focus works very well - it is slightly slower than the native micro 4/3 lenses, but good enough for me. This is larger and heavier than most micro 4/3rds lenses, but it balances well on the GH3, which prevents jerky motions while shooting video or stills. The image quality is very good.
Summary: I am a hobbyist that occasionally enjoys carrying my camera (Olympus E-520) around and shooting pictures. This lense actually makes my pictures look like I know what I am doing. It is amazing. I am so happy I bought it. I am one of those research people and everything I could find gave this lense high marks - even by the pros. I mostly take macros and portraits (of my pets especially) - the bokeh it produces is just beautiful. I would definetly recommend it.
Great lens for micro four thirds especially the OM-D E-M5

Summary: I bought this lens to use with my OM-D E-M5. The Zuiko 14-54MM II lens has an outstanding reputation for wide open sharpness across the entire zoom range. It was originally developed for Olympus' pro SLR E5 cameras. This is the only 4/3 lens that supports contrast detect autofocus (MK II version). It is a bit slower to focus and noisier than the current crop of micro four thirds lenses but in practice it works very well.
