Query: Good telephoto zoom, very good price

I bought my Olympus E-510 with the 14-42 lens. I wanted a longer lens to give me more reach when shooting distant shots of wildlife. I take this camera hiking, so I wanted a lens that was fairly light. This 40-150 lens was just the ticket. In stores in my area, I would have paid at least twice what I paid through Amazon, so the price was very good. Delivery took awhile because of the Christmas rush. I ordered it before Christmas and got it a little after New Year's, with normal delivery. I have not had time to extensively test it, but I found the lens was lightweight for its focal length, focused resonably quickly, and took sharp pictures at full telephoto. I was pleased that the lens was the same diameter as my 14-42 zoom, so I could use the same filters. So far, so good.
