ARRI Mattebox MB-20 - Manual (Page 8)

There is no need to compromise when
focus is critical or complex. The ARRI
FF-5HD follow focus system brings film
style quality and precision to digital
production, giving digital cinematographers
the control necessary to get the shot the
first time, every time.

For long lenses without support posts, the ARRI Dual
System Lens Support attaches to 15 mm, 19 mm
or lightweight support quickly with the same snap-on
adapters proven on ARRI’s FF-5 Follow Focus.
FF-5HD
Follow Focus FF-5HD
The ARRI Follow Focus FF5-HD, a completely modular film-
style follow focus, is now available for digital productions.
Designed specifically for lenses with a smaller diameter
focus barrel, the longer swing arm ensures proper gear
position on the focus ring. A lower gear ratio allows a more
exacting focus pull on smaller diameter lenses or those with
compressed focus scales.
The FF5-HD integral snap-on mechanism locks to 15mm
lightweight support rods and can be adapted to work with
ARRI Standard 15 mm or 19 mm bridgeplate support rods.
ARRI Follow Focus drive gears can be attached to either
side of the swing arm, allowing greater mounting flexibility.
ARRI gears are made from low friction Delrin for optimal
drive smoothness and use precise self-centering stainless
steel couplings to eliminate runout and wear.
For more options, the FF-5HD is compatible with all ARRI
FF-4 Follow Focus accessories. Right and left focus knobs
and the FF-5’s longer body allow operation from either
camera side with any lens. In addition, an extension is
available to clear the largest matteboxes. Short and long
focus whips allow the assistant to stand farther away from
the camera and a focus crank makes fast snap zooms
smooth and accurate.
