Sorry to repeat but it is nor true, at least with my copies.
With the R-D1s, the screw dedicated to RF vertical alignment has not the same orientation and is smaller than that of the R-D1.
Also, contrary to the R-D1, this screw is inactive with the R-D1s so that i cannot adjust vertical alignment myself any more.
As far as my bodies are concerned, the R-D1 and R-D1s are then different cameras from this standpoint.
