The OConnor 120EX Standard Film Fluid Head is famous for ultimate control and stability for film style shooting. Now, 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 new counterbalance mechanism at the heart of the EX-technology, the 120EX can be boosted into EX-mode to achieve a whole new realm of counterbalance. True and accurate balance is achieved through the sinusoidal EX-counterbalance technology. The EX-drag technology is ultra-smooth and stepless.
The EX fluid heads have a given payload range for the +/- 90 degree tilt range. With traditional counterbalance mechanisms any payload heavier than this maximum weight can't be balanced, not with the EX range of fluid heads. EX fluid heads can go far beyond that maximum payload by slowly limiting tilt range as the payload is increased.
The maximum payload is reached at a tilt range of +/-60 degree, which is much higher than the rate +/- 90 degree payload. With the example of the 120EX, the payload for a +/- 90 degree tilt range is between 30 and 120 lb (14 and 54 kg), but in EX mode the 120EX can counterbalance up to incredible 240 lb (109 kg) at a tilt range of +/- 60 degree; all based on a 8" center of gravity.
