This video was shot in order to show the issues I've been experiencing with the Manfrotto MVR911ECCN (Sympla clamp on remote) for the Canon DSLR's. This video shows how the focus motor overshoots or continues to be driven after focus input has been removed by the user.
The camera is running firmware version 1.1.3 and the Manfrotto MVR911ECCN (Sympla Remote) is running the most current version R-0006 which claims to support the 5D MarkIII.
I hope that the fine folks @ Manfrotto can get this issue resolved as I really enjoy having this tool available and would really like to work it more into part of my workflow.
I've also found that the Canon 70-200mm IS-II is the smoothest as the focus motor is being driven. The other Canon glass I've tested with I've found more noticeable stepping as the focus is driven back and forth.
