The Canon EF 14mm / 2.8 / L USM II is characterized by a very well-balanced imaging performance. Vignetting (Randabdunkelungen) are barely visible even with a camera with full-frame sensor (EOS 5D Mk II). Then I could find only minor distortions. And that's already considerable power in a super wide-angle lens. Also chromatic aberration (CA; fringing) are visible only with a magnifying glass and are actually negligible. The lens is particularly suitable for architectural or landscape photography. But the creative photographic artists can get their money, especially if they exploit the image quality for close. Negative point is primarily the price. The latter is quite proud with more than 2,000 euros (as of 20.03.2012). Wichitg knowing still that the lens on the Canon body with autofocus works (who can verziczhten on the autofocus can also for a few hundred euros a comparable Wallimex lens or the like. Buy). I myself do not want to dispense with the autofocus function. With autofocus photography is simply more convenient in the long run. Last point: Filters can not be used. This means that you should treat the lens particularly careful because you could catch due to curved lens quickly once scratch. So always the lens cover on it, unless you're photographed.
