DIY follow focus knob
I got an idea while i was looking at the rear lens cap of my 70-200mm lens. It is the perfect size for a follow focus knob.
Combine it with the camera body cap and sandwich a plastic disc in between the two and you’ve got half of the diy follow focus ready!
The lens caps go for about $2 for a set of two on ebay .
Combine that with a HUCO L gearbox and some gears and you have yourself a very cheap DIY follow focus.
I’m going to order an L gearbox soon and test this out.
