For several weeks, we have the objective to our Lumix G6 and are very pleased with the recordings thus made. Class in normal daylight throughout the entire zoom range and in low light very good shots. Extensively test a few weeks ago during a trip to Rome was very positive. Pictures inside the attractions are very good despite some poor lighting conditions. Here speaks not the freak but the demanding amateur photographer. I hope it helps you. I would buy the lens in there again.
