These are photos I've made with the Olympus M.Zuiko Digital ED 12-100mm f/4 IS PRO Lens. This lens is built very, very well. It's sharp, weather sealed and it's also beautiful ;-). It's also stabilized, so if you're using it on a body that doesn't have in-body IS, you're covered there too.
I have a video about the outstanding 12-100mm on YouTube.
