Following on from Part One, I have come across a number of ways of changing the focus ring via a servo, and if I was to use a Telephoto (Zoom) Lense on an SLR (Single Lens Reflex) Camera The Focal Length as well:

• Shoulder Rig
• Geared Follow Focus
• labeled lensgear-set for Geared Follow Focus

With my 3D printer being started, and hopefuly latter this week more of it being produced (by Nathaniel Poate) I should be able to print more of it myself.

I have been working on some ideas using micro servos, my iPhone and an application called 360 Panorama, the code for which should be added to my projects section soon..
