I agree. The initial image is from the FS4000 film scanner and the
roll-over is the 5D/80/4 shot.
What's interesting is that the 5D image has been upsampled almost 30% to
match the FS4000 output. I haven't tried the other direction yet.

Doesn't exist. The slide duplicator bellows is barely long enough to do
1:1, otherwise, everything is broadly adjustable. I used the Oly 7mm
extension tube, but one could use a longer one, just shorten the bellows
extension by an equal amount. No problem at all.
