This objective is not bad, of course. He does this job without worry. But I do not see him at the place where most of the comments. Certainly on my GH2, it's a little better than the original 14-42 set to the same focal level "artistic" and for the dive, while a brighter diaph. But there is worse than an old Canon AF lens with 4/3 ring which comes significantly cheaper (with the only advantage to accept the autofocus). I'm a bit disappointed so.
