I'm getting great results with this little lens on my Olympus PEN system. This is a great little pancake lens that delivers the full-frame 56mm equivalent. But you can't trust the infinity focus marker or believe that the point at which the lens' focus ring stops rotating is infinity - it definitely isn't. If you're holding a small suction cup, be aware and perhaps adjust it by taking it apart and calibrating it if it's worth it. There are several videos on YouTube on how to do this.
