The focus seemed to be tighter. I don't know if this is a result of stretching the pixels and being able to see the focusing better, but it did look better doing the focus in the stretch mode first.
I may have that definitive answer I was looking for, and it ought to address what you've just described Willy.
This is from an email exchange between myself and Prismasonic:
> Why are these guys saying there's a focus change between passthru and stretch?
They are right. There is a little change in focus between the 'pass' and
'stretch' modes. However, the change is not visible, especially if one does the
focusing in the middle of the 'pass' and '2.35:1 stretch' modes. H-1000 allows
to do that because it is truly variable. Doing so there is no need to refocus
the projector manually, and thus it will be 100% automatic.
Makes sense. Willy: Can you try it? Focus in the middle of the 2 modes.
