Nikon 28-70 f/2.8D ED-IF AF-S
My most used lens for infrared on the Canon EOS 5D. Though it also performs well on the Nikon D70, it is much larger and heavier, with a far smaller range than the 18-200 VR (the latter also sports Vibration Reduction). Its backfocus is much stronger than that of the 18-200. Putting all those issues together means that I stick with the 18-200 on the Nikon D70.
Hot spots, while present, are rarely visible in actual field shots. Image sharpness across the frame is impressive, even on the full-frame EOS 5D (see the EOS 5D assessment).
This lens earns a “Recommended” for its high optical performance, even wide open at f/2.8.
