The World's First Autofocus Conversion of Contax N lenses for Canon.

Many of the lenses tested here came from Adorama. Brooklyn remains one of the cheapest places on earth to buy kit from. These guys are not only reputable and friendly (for New Yorkers) they ship anywhere.

As at f2.8, the Nikon has all the kudos until we consider the corner. Note in its defense, however, that the Nikon 17-35mm's CA blight at 17mm is much improved at 21mm. It's still there, but it's on the way out. The gulf separating the two with regard to corner performance is also narrowing: an early sign that the Contax N isn't going to have this comparison all its own way.
