I bought this lens as a supplement to my e-M1 and the 12-40 2.8. With the right handle the camera and lens are very good to touch. It's totally fun to photograph it. Good thing I have saved the 150 euros for the cheap and faint lens. This part is worth every euro. I have shown my children on the beach today, doing some very beautiful pictures were taken. I have captured beautiful moments, that's priceless. I got beautiful pictures. I'm glad.
