The lens I use in conjunction with a tripod to the Jay razor in my garden scan sharp. And it works! In the relevant forums is indeed like towed on Olympus cameras and related objectives. This can and I want to refute this review! Are very good, absolutely demanding photos possible with a underdog as the Olympus E-30 in connection with this exceptional lens. The lens makes a very valued and reliable impression. Also, a lens hood is! And has it all: A slider enables a portion of the front lens, for example, to adjust a polarizing filter. This is with other manufacturers often costly Extrazubehör.Nicht so at Olympus. Focusing is very quick and quiet of equip, so that even shy animals are not chased away. I can absolutely recommend the lens for nature photography. It is a pleasure to zoom zoom a jay or a robin, and scan even the finest details of plumage properly. Really high-class photos that were taken with this lens, can be found at Fotocommunity.de
