In addition to the E-M5 Mk II I ordered next to 9-18er directly this lens, although I 17 1.8er and 45 1.8er already had that. I had. Only slight concern about my use intensity, because I was never happy at the NIKON (Crop) with 50 mm equivalence by the image effect (visual impression) and they had sold quite quickly At the E-M5 Mk II but the lens has become my absolute favorites! Affordable, easy, well finished, silently, fast, sharp - what more could you want?
