Dan,
It has been closer to twenty-five years since Nikon introduced a new, upgraded lens. Fuji introduced their CM-W series of lenses about ten years ago. The CM-W series is an upgraded version of Fuji's W lens series. By designing their lenses so that they have fewer cemented elements, Fuji has been able to make some outstanding improvements and a couple of unusual lenses. For example, the new125CM-W lens has a 204mm. image circle, and, as far as I know, Fuji is the only manufacturer making a 105mm. wide angle lens. Their 450C is mounted in a Copal 1 shutter. Because these lens designs have fewer cemented elements, they have more reflective surfaces. Fuji claims that their EBC (electron beam) coating is able to eliminate the reflections that cause internal lens flare. From what I can see, it certainly seems to work.
