I have days that lens only for a few, the first results are stunning, and I have certainly brought out not all of the lens. The picture quality is simply stunning. It is not for nothing that one of the best ultra-wide-angle zoom on the market. Extremely sharp and bright. Dust clouds and thunderstorms to the lens by the sealing harm. I can only recommend this lens and say simply times it every photographer whether Hobby / or professional photographers will delight in equal measure. The lens is super processed and the resolution is just great. I can already say that it belongs to one of my best lenses from Olympus. 800 Euro are not a trifle, but compared to the 1,600 euro expensive 7-14 millimeter Olympus lens comes almost bargain-mood.
