This is reputedly one of the sharpest macro lenses (and portrait lenses) available today. AF works fine (albeit slowly) on my E-PL1. THe lens is in superb optical and physical shape and all works as it should. You'll need an Olympus or Panasonic adapter to use this on a m4/3 body. CONUS US$325 shipped/Paypal Canada C$300 shipped/EMT I also have a Lumix adapter for sale - see my other listing.
