The lens I use for a few weeks. The lens has only a plastic case, but it is also incredibly light. The quality of the recordings are very good, it can be also nice to play with depth of field, which is not so possible with the 14-42mm standard lens from Olympus. The autofocus is fairly quiet which makes it theoretically is also suitable for recording videos. Due to the large focal length, however, take the pictures and you have but are very far from the subject away. But I have not even bought, but to capture as a "holiday lens" distant objects. But it works beautifully. The light intensity is very good for the focal length, thus helping to bring the shooting itself blurred rarely with vorgeschraubtem filter. Top!
