REASONABLY Priced Follow-Focus/Mattebox?

Recommended Posts

does anyone have a source for a REASONABLY Priced Follow-Focus/Mattebox? After hunting, and price comparison, I was shellshocked. My God! You could almost buy another camera for what they want!

 

here's one for $600.00 im not sure of the type camera you have???

no, it doesn't. a real focusing ring has one position per distance, a scale that must remain constant as you zoom in and out, and it racks focus immediately when you turn it, not afterwards at a fixed speed using a servo. if these criteria are not fulfilled a follow focus isn't very useful. can you still focus accurately with the z1? sure, but that's another story.

You mean the camera racks focus when turned on even if the autofocus is off? Isn't anyone using a follow-focus on the Z1? Are you sure?

The Z1 uses a servo mechanism, meaning that the focus dial is not directly mechanically connected to the optics of the lens. If one were to wrap tape around the focus ring and mark off various distances, when switching the camera off and then on these marks would no longer be accurate. This greatly hinders the use of a follow focus device.
