Tip lens without lens hood (actually a shame) of Olympus, which has always built very good lenses. I was surprised about the excellent imaging performance this lens. Despite stability but it will be for the 300 mm KB-sector 600 mm, require a tripod. It's not quite as easy as many other MFT lenses, but to handle very well. Can I fully recommend. It is worth its price. What is missing is the lens hood, which is actually part of the lens.
