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.

Some of the advantage the Contax enjoyed over the Nikon at 17mm is whittled away at 21mm. The 17-35mm N still has marginally better corners, but the margin is diminished, and the Nikon is generally better across the frame.
