cineAKS recently got commissioned to make a push on adapter for the ARRI cforce mini for use on rehoused lenses that have deeply recessed iris rings. This led to them creating the ARRI cforce Mini Focus Gears & Offset Adapter Gears (m0.8).
This range of focus gears was developed to solve a common issue encountered when using rehoused lenses with recessed iris rings, where standard ARRI cforce Mini gears cannot reach the lens gear without interference.
The original request was for a push-on adapter gear to convert the ARRI m0.8 40 tooth gear into an offset 80 tooth gear, providing clearance while maintaining reliable engagement. From that starting point, the range was expanded to include direct-attach and extended-width gears to cover a variety of focus and iris configurations.
All gears in this range have been tested on ARRI cforce Mini motors. Based on mechanical compatibility, they should also work on ARRI CLM-5 motors; these have not been tested, and compatibility cannot be guaranteed.
This product is sold as a single product with multiple variations, allowing you to select the gear configuration that best suits your setup.
AVAILABLE VARIATIONS
- m0.8 40 tooth to m0.8 80 tooth push-on adapter gear with 8mm offset
- m0.8 80 tooth direct-attach gear with 8mm offset, reuses your original ARRI fixing screw
- m0.8 40 tooth extra-wide gear with 25mm face width, reuses your original ARRI fixing screw
- m0.8 40 tooth standard gear with 8mm face width, reuses your original ARRI fixing screw
