Sigma 30mm f2.8 lens DN (46mm filter thread) for Micro Four Thirds lens mount black (Camera)
This is my subjective opinion, even with this lens the rattle is due in the off state to the slats in stability, so no shortage (as well as the 19er 2.8er, I can live with this). Interesting focal length, as well as the 19er at the OMD EM5, very good
