This lens is one of the biggest competitors of the ZUIKO 14-150mm lens from Olympus and also has built-in image stabilization and a very fast autofocus. While it has these benefits, the price and weight are also higher. The best choice would be to buy this lens together with a DMC-GH1/2 camera from the same manufacturer as part of a kit.
