Olympus Zuiko Digital 9-18mm f/4.0-5.6 ED DSA Lens.
I have had a short time to use this lens. I am very satisfied with the result so far, I have wanted a wide angle lens for some time but did not want a fish eye lens. The result so far at 9mm is good. I want it particularly for landscape and architecture, I look forward to exploring this element of photography. I am using this lens on my Olympus EP2 micro four third , with an adaptor four thirds to micro four thirds, no problem it's just a bit longer than the dedicated lens, however it cost me half the price so I can live with that.
