DJI Zenmuse X9 Counterweight

DJI Zenmuse X9 Counterweight – Tilt-Axis Balancing Weight for Ronin 4D

The DJI Zenmuse X9 Counterweight is a dedicated balancing accessory for the Zenmuse X9 gimbal camera used on the DJI Ronin 4D cinema camera system. DJI states its purpose plainly: when heavy lenses are used on DJI Ronin 4D, this counterweight can be used for adjusting balance on the tilt axis. On a gimbal camera that job matters, because a tilt axis that cannot be balanced properly forces the motors to work against the lens weight on every move.

The counterweight itself weighs 294 g. It is listed by DJI as compatible with the DJI Zenmuse X9-6K and the DJI Zenmuse X9-8K, the two versions of the full-frame Zenmuse X9 gimbal camera fitted to Ronin 4D. In the box, DJI supplies the X9 Gimbal Counterweight, four M3-6 countersunk screws and a 2 mm ball-end hex key, so fitting it on set needs no additional hardware.

Why tilt balance matters on Ronin 4D

A gimbal can only stabilise smoothly when each axis is balanced: the camera should hold its position without the motors constantly pushing to keep it level. Fitting a heavier lens moves the centre of gravity forward, and the tilt axis is where that change is felt first. Adding the correct counterweight at the gimbal restores the balance point, so the tilt motor works within its intended range. Balanced axes also respond more predictably to intentional camera moves and place less continuous strain on the system during long takes.

When you will reach for it

The counterweight earns its place in the kit whenever the lens choice changes the front weight of the X9: faster, heavier primes and larger zoom lenses are the typical cases. Swapping lenses means re-checking balance each time, and having the official 294 g counterweight to hand means that check ends with a properly balanced tilt axis rather than a compromise.

Fitting and kit notes

Fitting uses the supplied M3-6 countersunk screws and the included 2 mm ball-end hex key, following the Ronin 4D and Zenmuse X9 documentation for the correct mounting position for your lens configuration. After fitting, balance the tilt axis again in the usual way before calibration and shooting. Note that this is the 294 g X9 Gimbal Counterweight sold as a separate accessory; it is a different part from the smaller counterweight included in some Ronin 4D camera combos.

For Ronin 4D operators who change lenses, the Zenmuse X9 Counterweight is the correct, manufacturer-made way to keep the tilt axis balanced with heavy glass fitted: a precise, single-purpose accessory that keeps the camera system working as DJI intended.
