You can use the bellows unit with the MZ-S. I have a Bellows K, and found it wouldn't fit when the BG-10 grip was installed, until I realized you can loosen the setscrew on the bellows mount and rotate the unit 90 degrees. There's no clearance problem, but the camera is in the vertical position. Depending on your subject, that may not matter, since you're using the vertical grip.
The fact that it's a manual unit does make it slow to operate, and best for non-moving subjects. Pat White
