Compare the SmallRig Articulating Arm 2066B (9.5") and 2065B (5.5") to find the right length for your camera rig, based on reach, stability, and weight.
Quick answer
Choose the SmallRig 2066B (9.5") when you need extra reach to position accessories away from the camera, and the 2065B (5.5") when compactness and a lower profile matter more.
Reach vs. stability: the core trade-off
The main difference between the 2066B and 2065B is arm length: 9.5 inches versus 5.5 inches. That extra reach lets you place a monitor or light further from the rig, which helps with viewing angles or lighting positions. But a longer arm also extends further from the camera, which can increase leverage and make the setup feel less stable, especially with heavier accessories.
For run-and-gun or gimbal work, a shorter arm keeps everything tucked in and reduces the chance of accidental bumps. For studio or desk setups where you want a monitor at a specific height or angle, the longer arm gives you more flexibility without having to move the whole rig.
Weight and accessory size considerations
Both arms use 1/4"-20 mounting screws at both ends, so they work with a wide range of monitors, lights, and microphones. However, the longer 2066B may struggle with heavier loads when fully extended, while the 2065B's shorter reach often feels more rigid for compact setups. If you're mounting a small LED light or a lightweight monitor, the 2065B is likely sufficient; if you need to position a larger accessory at a distance, the 2066B offers the reach.
Trade-offs at a glance
- Reach: The 2066B provides 9.5 inches of reach, allowing you to place accessories further from the camera. The 2065B offers 5.5 inches, keeping things closer. If you need to position a monitor or light at a distance, choose the 2066B; otherwise the 2065B is more compact.
- Stability: A longer arm can feel less stable with heavier accessories due to increased leverage. The shorter 2065B tends to be more rigid for compact setups. For heavy loads, consider the 2065B or check the weight rating of your specific accessory.
- Portability: The 5.5-inch arm folds into a smaller footprint, making it easier to pack and less obtrusive on a gimbal or small rig. If you travel light or use a gimbal, the 2065B is the more practical choice.
