While it's ultra compact design, excellent MTF performance and impressive technical specs looked quite impressive, I've read about several complaints of poor optical performance. Some state it's likely related to a defect in the positioning VR lens element causing blur/image doubling. I was planning to use it on my Oly EM-5 to replace the Oly 14-42 (1st version) and want know if Panasonic had fixed this yet.
