http://www.cinema5d.com/news/?p=4275The Arri MFF-1 is one of the best follow focuses you can get for HDSLR work.
The adjustable rotation of the follow focus is a great feature when using Canon lenses.
The entire gearbox flips over to reverse the rotation of the gear, which works well for Nikon lenses.
It is the most expensive at around
$1700 US.
The Chrosziel DV Studio Rig follow focus is very sturdy and the gear can be positioned
in either the front or back of the gear drive. This is helpful when you must get close
to the camera body with smaller prime lenses.
The knob is large which will add more rotation to a short throw lens,
like a Canon Zoom. They also make a “Varilock” knob with adjustable rotation.
The Chrosziel DV Studio Rig shown here costs around
$1500.
Zacuto’s mid level Z-Focus follow focus was very smooth right out of the box.
Most follow focus units are fairly stiff new and will loosen up a bit over time.
The gear can also be positioned in the front or rear of the drive.
The gear was a little small on the unit we had but that is an easy fix.
The Z-Focus is $1350 US. They also make a “Flippable Reversible” version for
$1675 US.
The
Red Rock Micro Follow Focus V2 was the least expensive of the bunch at less than half the price
of some of the other units. The prime gear cannot be flipped from front to back
and the indicator marker is flimsy, but this is a great follow focus for the price.
I have used one for over a year without problem. The Red Rock Micro V2 costs
$545 US.
There are many other types of follow focus units on the market ranging from
the
$150 D-Focus, to well over 1K by companies like Vocas, Cinevate, and Genus.
The five shown were just some of the popular follow focus units on the market readily available to us at the time.
