Nikon 17-35 f/2.8D ED-IF AF-S
A very fine optical design, this lens has caused me so much grief over the years by going out of optical alignment on a regular basis that it mainly sits in the drawer. However, its optical quality is extremely high in visible light, provided that the lens is in perfect alignment.
A test of the lens on the Canon 5D-IR showed extreme degradation in image quality away from the optical center, and as a result it’s performance has not been explored further on the 5D. And with the more than satisfactory performance of the 18-200 VR on the Nikon D70, the 17-35 has not been an attractive candidate for further research.
