Follow Focus Ring

prusaprinters

<p>Autofocus is rarely used in professional film making because the focus mechanisms are not smooth enough to be adjusted while the camera is rolling. &nbsp;Instead, the focus ring on the lens is rotated manually using a geared hand controller called a follow focus. &nbsp;Sometimes the follow focus is turned by the camera operator and sometimes there is a dedicated member of the camera crew called a focus puller.</p><p>This Follow Focus Ring is a simple design to allow for easy focus or zoom controls while behind the camera. &nbsp;Reach arounds are nice and all, but can produce a less precise result compared to using a ring.</p><p>Inside diameter is 58mm, 60mm, 64mm, 68mm, and 72mm… held on with a simple rubber band. size does NOT need to be exact to fit your lens, I would error on larger. &nbsp;You can scale to any size lens to control Focus or Zoom or BOTH!&nbsp;</p><p><strong>HINT: I have also heated one and compressed is slightly to fit tighter.</strong></p><p>Let me know if you need a specific size and id be happy to design.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Remixed from: https://www.thingiverse.com/thing:1066905</p>
