SmallRig 2791B is perfect for vlogging, live streaming, and mobile filmmaking. It works perfectly with most mobile phone models on the market and is compatible with mobile phones with a width between 57mm and 90mm, with or without an external case. It uses screw clamping instead of pressure, which provides a more stable locking effect. It features four mounts for a microphone and an LED light. Multiple 1/4" threaded holes can be used to attach a tripod, top handle, or side grip. The 1/4" threaded holes at the front can be used to connect the power bank holder, which allows you to attach a power bank to the rig when a sustainable charging solution is needed. It supports both horizontal and vertical shooting. Integrated rubber pads help absorb shock and prevent the phone from scratching. Two cable ties are attached, which can be used to organize messy data and microphone cables during shooting. It is lightweight and easy to hold.
