It's strong enough for the 1DS2 when not configured with the second
small bracket. (as I mentioned... the small bracket is not part of it
anyway, its a "separate single row" pano bracket.)

I have used adhesive camera seal foam between the small bracket and
cam (when configured in single row mode) and adhesive camera seal felt
between the macro rail and bracket.... so nothing moves unless the
mount screws are loosened. The macro rail comes with a rubber mount
for the camera, so that stays put also.
I got the foam and felt in a kit off ebay for 10 bucks. I resealed my
OM1 and still had more than enough to do the pano head.
