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.

More of the same, I'm afraid: fabulous corners from the Zeiss; still with the resolution trough. By f8, the Nikon has sorted out its focal plane ripples and is as good centre frame as you could wish, though it must be stopped down further yet to render a sharp corner.
