Who Should Buy SmallRig 1138?
Good fit
Choose this SmallRig clamp if you need an adjustable clamp-on mount for cameras, webcams, monitors, lights, microphones, or action cameras. Its 1/4"-20 screw and compatibility with rods, tubes, tables, frames, and tripods suit varied filming and desk setups.
It makes sense for gear that fits within the up-to 1.5kg capacity and for users who value a compact mount that avoids drilling. Use the supplied action camera adapter when that connection is the one your camera needs.
Who should skip it
Skip it if your rig exceeds the up-to 1.5kg capacity or your setup requires a mount that does not depend on clamping to a compatible support.
For dynamic placements, avoid relying on the clamp alone: plan to attach a safety rope as part of the setup.
SmallRig 1138 in a Compact Camera Rig
A clamp and ball adapter in one mount
The combination of a super clamp and double ball adapter is the core reason to consider this model.
It offers an attachment point and adjustable positioning without requiring drilling, which can simplify temporary camera or accessory placement on a compatible surface.
Check the load before mounting
The up-to 1.5kg capacity is a practical boundary for choosing the camera and accessories. Weigh the complete mounted setup, including attached gear, and leave margin if movement or vibration is expected.
Choose a compatible support
The clamp is intended for support types such as rods, tubes, tables, frames, and tripods. Think about where the clamp will sit and whether the locking knob can be reached once the camera is in position.
A useful adapter for action cameras
An action camera mount adapter comes in the package, adding a ready attachment option for compatible action camera setups. Buyers using other gear can rely on the 1/4"-20 screw for the listed camera and accessory types.
