The accessory bar from DM arrived today.

It didn't fit on the top of the FX1/Z1 shoe mount as the second stabilizer screw was tad too close. I'll try to shave it a bit. This stabilizer bar fits well below the camera in the plate mount, but doesn't offer more metal to allow for mounting to a plate. When mounted on the bottom side, it's hard to grip the camera from the wrist strap side.
