Maximum payload capacity and limitations of the Max EFP gimbal for camera stabilization
17 years old. Gear and prices may have changed since.
What the thread found
- The EFP gimbal was designed specifically for video cameras and is rated for a maximum payload of 39 pounds or approximately 17.5 kilograms
- The EFP gimbal uses cast construction while the more capable 3A gimbal uses machined construction, making the EFP gimbal intentionally weaker
- Early EFP models with blue springs handled 12 to 24 pounds, while later models with black springs handled 24 to 39 pounds total payload
- Using film cameras like an ARRI 535 on an EFP gimbal exceeds the rated capacity and risks structural failure from accumulated stress and hair fractures in aged equipment
- The EFP gimbal and 3A gimbal share similar external appearance but differ significantly in internal construction and load capacity by design
- Upgrading individual components like the arm or vest does not increase the gimbal's load capacity, as the gimbal itself remains the weakest link
- Alternative gimbals such as the BFX ACME gimbal can be retrofitted to EFP rigs and handle larger camera weights while maintaining compatibility with the standard 1.50 inch post
- A carbon fiber post can replace the original EFP post if the original becomes out of round from use
Depends on
- The EFP was intentionally manufactured with reduced capacity compared to the 3A model to maintain market differentiation and pricing strategy
- Most EFP units in circulation have experienced decades of use and potential abuse, introducing structural weaknesses not present in new equipment
- Information reflects gimbal design practices from the 1990 era and earlier EFP models
- User reports of successfully carrying heavier cameras represent extreme use cases and do not validate safe operating practice
- Horizontal balance positions with heavy cameras create additional stress that may accelerate gimbal failure
