Extended capacity 120EX Fluid Head for cameras up to 120 LBS (54.0 kg) or 240 LBS (108 kg) in extended mode

I simply couldn’t get what we get on ‘Bones’ without OConnor there to support us (using two 120EX fluid heads)

Industry leading cinematographers are turning to the OConnor 120EX head. With the smooth OConnor feel and infinitely adjustable control, this patented head is the only product on the market to balance the huge capacity range of 30 – 240 lbs (14 – 109 kg).

OConnor’s fluid heads are famous for ultimate control and stability for film style shooting. With the use of EX-technology OConnor can offer the features it has become famous for while offering an additional benefit: extended capacity. With a patented stepless counterbalance mechanism at the heart of EX-technology, the 120EX can be boosted into EX-mode to achieve a whole new realm of support.

Getting more than 100%! This is the best way to describe the EX-Mode.

The 120EX head has a given payload capacity of 120 lbs (54 kg) for the ±90° tilt range. With traditional counterbalance mechanisms any payload heavier than this maximum weight can’t be balanced.

Not with the 120EX

EX fluid heads can go far beyond their maximum payload by slowly limiting tilt range as the payload is increased. The maximum payload is reached at a tilt range of ±60°, which for the 120EX is an incredible 240 lbs (109 kg) based on a 8” center of gravity
Have the freedom to create with even the largest lens: choose the 120EX.

Only available with the 120EXe

The 120EX head is available in a separate model with digital output: 120EXe

The OConnor 120EXe encoded fluid head is designed to provide high-precision pan and tilt position information for cinema quality visual effects production for feature films and commercials.  Such positioning information is also critical for optimizing 3D productions in post production.

The 120EXe provides output pan and tilt position information via an external 19 pin Fischer connector.

A companion encoder box is available as an option for the 120EXe.  This allows high resolution pan and tilt data of 1.8 million counts per revolution to be output from the head, making it suitable for film and HD formats.

When the 120EXe is coupled with a 3rd party data logger, it instantly becomes a powerful camera motion capture system for use in post production.  When used with a pre-viz system, it also allows real-time previsualisation of live action and CG compositing on set.
