Given the focal range, it would be an extremely difficult, if not impossible, task, and costly, to make the corners sharp at all range and f-stops when mounted on the Merrill. Probably will look great on the older cameras.

Even Nikon's legendary 14-24 and 24-70 have some softness when mounted on the 800/800E.

They do. But the 18-50 and older 17-70 have the tendency to really drop resolution the farther away you get from the center so that the center of the SD1 photos look magical but as you get farther from the center the resolution drops off. While extreme edges of the 14-24 and 24-70 may have some softness you don't notice a resolution drop off from the center of the lens on large prints. I hope the new 17-70 acts the same way.If not, that still leaves a big hole in the lens line up for the SD1.
