The 4D Speed Crank with Zero Backlash Coupling is an optional accessory which allows you to pull focus precisely when fast movements are required.
The expansion coupling is compatible with both the Revolvr handwheels and other handwheels using the industry standard square port, and is the only coupling in the market allowing for perfect attachment with zero backlash.
It is also ideal to operate while pulling focus in tight spaces as the speed crank can be connected directly to the core bridge, without use of the handwheel.
The handle lever can be pivoted from the standard 90° up to 130° for comfortable positioning and is extendable by over 2 inches in length for extra flexibility.
It has been carefully crafted and assembled in Germany and built from anodized aluminium and stainless steel to ensure maximum durability and resistance from wear and tear.
