YES! I have wondered why Nikon don't do the same thing within the range of
their scanner Depth of Field. It would nearly double warping that could be
tolerated before losing focus. The only downside is that you would have to
put the film/slide in the "right way round" regarding film curve, not
regarding mirror image sense. This would not be a problem if documented
clearly.
