Seems good. Use it on DJI Inspire 1 v2 Pro with Zenmuse X5. It seems quite noisy and not very smooth to zoom. It seems to jump a bit from one zoom level to the next zoom level. Images look fairly sharp, but not as sharp as one of the fixed focal length lenses (25mm or 45mm M.Zuiko). I hoped that would save me the landing. and change lenses for different shots, but I don't think so. It's a good lens, good enough to use and enjoy. I don't know if it's enough for professional work. For hobbyists and people having fun I think this is a good lens. As usual, you get what you pay for (and it's not a very expensive lens). Worth the money it's worth? Definitive. Just trying to be honest with other Inspire pilots who are considering buying one. I hope this helps anyone who has doubts about the purchase.
