After my gearless follow focus,
here a geared one.
Swapping the lens is not as easy as it is with the gearless one and you
need a lens-gear for every lens but you also need no pressure to create
The follow focus and lens gear are compatible with industry standard 0.8 pitch follow focus equipment.
The axis use 608 bearings to reduce any noise of threaded rods on
plastic that could be picked up by the microphone and to make this run
as smooth as possible.
The mounting is for an industry standard 15mm rail support system such as
my 3d printed shoulder rig:
With a follow focus you have precise, manual control over the focus (or zoom) of your lens.
It is used for professional filming where precise control of the focus
is required and where a pumping autofocus would simply ruin the take.
Commercial versions are sadly terribly expensive. :(

Added lens_gear_version3 with a wider tap for the bolt.
What gears? There are 3 of them.
The gears slip a little even with bolts and washers. Suggestions?

- works great. the 90 degree gears printed also great but had a weird finish that it didnt get rid off. still works great and could be solved by small corrections by hand. all the other parts came out perfectly.
