Remote Focus control of 16x manual lens
 
What can I use that will allow me to be able to perform a rear focus on a Canon 16x Manual Servo Lense while mounted on a JIB?

I don't quite understand your question. Back focus is a semi-permanent type internal adjustment on the lens to insure proper focus during zooming in and out. What are you trying to do?

I am talking about placing XL2 Camera with a Manual 16x Servo on a JIB and being able to manually focusing the lense with some sort of remotly managed devise like the Canon MS-15 Rear Focus Control Unit. My question is, is there a similar device for the 16x Manual Servo Lense?

Please view attachment.

The proper term is not rear focus or back focus. The proper term is remote focus control.

Anyway, this is what you need:

Interesting Chris--I had assumed that this was a question about wireless lens control (i.e. Preston, Bartech) when i saw the title, as that is my association with "remote focus". Going back into my dusty memory banks I used to say "rear-mounted zoom control" when ordering a rental video camera package so I would apply the same to focus, although I never used those.
Alternatively, "studio zoom/focus controls".

Ah so... I guess the video market is to blame for muddying these waters!
