John Iver Berg Posted October 16, 2009 Share Posted October 16, 2009 Hi, We start shooting a 3d feature early next year, the plan is to use two Canon 5d on a mirrorig. What would be the best solution for a remote follow focus on this setup? I've been in contact with BarTech Engineering, witch has a great follow focus, but i learned that i have to use digital motors, and BarTech is designed for analog motors, and isn't accurate enough. quote from Jim Bartell "The best potentiometers have a linearity specification of 1%. This is not nearly enough to control two lenses precisely over their range of travel. While two motors may match up there is no guarantee they will. It has been tried and the results were unsatisfactory." any suggestions of what remote followfocus to use?

Ross Neugeboren Posted October 16, 2009 Share Posted October 16, 2009 Element Technica's 3D beamsplitter system has successfully employed the Arri lens control system for precision syncing across both cameras (In this case, RED's) You could try contacting technica3D for more information. http://www.technica3d.com/contact/ The system is shown in use on the 3rd album on the page.

Premium Member Phil Rhodes Posted October 16, 2009 Premium Member Share Posted October 16, 2009 I hate to throw a spanner in the works here, but have you figured out how you're going to sync two 5Ds? P Link to comment Share on other sites More sharing options...
Tony Coan Posted October 19, 2009 Share Posted October 19, 2009 (edited) I just noticed C-Motion is introducing a software update for the use of their FIZ units for 3-D. Here is an article. http://cmotion.eu/cms/index.php?option=com...116&Itemid= Edited October 19, 2009 by Tony Coan Link to comment Share on other sites More sharing options...
