Years ago Intuit released a belt driven remote follow focus system (seen in video above). The product looked like an excellent idea, but the retail price listed for $3,999 US (seen here). Needless to say it didn't exactly fly off the shelves.
Opteka has revised this basic idea and now offers an FFR-900 Motorized Belt Driven Follow Focus System. The FFR-900 doesn't just offer one, but two motors that clamp to 15mm rails to control both focus and zoom on your DSLR lens. Rocker switches to control the motors are mounted to 15mm hand grips, and sensitivity (i'm guessing speed) of the system can be adjusted in a rear controller. The motorized FF is powered through standard Canon LP-E6 batteries (batteries and charger included).

From what I can tell, the motors can be controlled by the main controller, and the rocker switched handles don't need to be plugged in. This could be a handy solution for Steadicam work, but keep in mind that it's basic forward and reverse DC motors. This will work if you're moving around and your focus points continuously change, but unlike a real motorized follow focus system, you can't program multiple focus points in and jump back and forth which is ideal for stationary tripod shots.
While the Intuit version is sold for $3,999 the Opteka FFR-900 is sold for just $399 and is bundled with a modified CXS-300 shoulder support rig. What do you guys think? Is this a Hit or Miss? For additional information, the Opteka FFR-900 Remote Follow Focus system can be found via eBay (click here).
