Last year I jumped onto the M4/3 bandwagon with a Lumix GX7 and haven't looked back since. Recently I added several lenses to my kit lens arsenal and now I'm looking to add the Olympus PEN Mini E-PM2. I've read over every review of the Mini I could find and then cam across this lens that caught my eye. I don't recall ever seeing this lens before ? Somebody fill me in please.
