Overview
Key Features
【Formfitting Design】 This NEEWER CA021 rotatable collar camera base plate, made of CNC anodized aluminum alloy, is fully compatible with Sony Alpha 7R IV Alpha 7R V Alpha 7 IV Alpha 7S III. It enhances balance when using telephoto lenses, enables seamless switching between horizontal and vertical shots, and allows full access to the camera's LCD flip screen, ports, and functions while securely mounted on a tripod
【Quick Horizontal to Vertical Switch】 Rotate the lens collar mount 90 degrees and secure it with the thumb screw to achieve a quick, easy switch between landscape (horizontal) and portrait (vertical) orientations without having to adjust the heavy lens, which saves time and effort in repositioning. Note: Only supports lens adapter rings with less than 63mm diameter. Please remove the lens adapter bracket (if any) before use
【Anti Twist Secure Lock】 The advanced locking system allows your Sony Alpha mirrorless camera to be firmly fastened via an anti twist 1/4" screw with locating pin and the cross patterned rubber pads on the mounting plate. Five additional nonslip pads inside the collar increase stability and prevent scratches to the lens. Two L shaped hex keys included to tighten your camera without extra tools
【Efficient & Safe Lens Release】 Simply press to remove the longer telephoto lens, minimizing the risk of accidental falls. This feature is especially useful when switching between different lenses during a shoot, ensuring a smooth and efficient workflow
【Quick Release Camera Mounting】 Both compatible with Arca Swiss standard and even compatible with DJI RS 2/3 quick release system for swiftly mounting on any tripod, gimbal, monopod, and slider with an identical tripod mounting system. With 4 x 1/4" and 1 x 3/8" threads on the camera mount plate bottom to be mounted on camera rigs, hand grips, and more. Not recommend using it with a gimbal due to the balance issue

Frequently Asked Questions
Which Sony cameras is the Neewer CA021 collar mount compatible with?
The CA021 is specifically designed for the Sony Alpha 7R IV, Alpha 7R V, Alpha 7 IV, and Alpha 7S III. It will not fit other Sony body shapes.
Can I still access the camera's flip screen and ports with this mount attached?
Yes. The formfitting design leaves the LCD flip screen, cable ports, and all camera controls fully accessible while the camera is mounted.
Is the CA021 compatible with Arca Swiss tripod heads?
Yes. The base plate conforms to the Arca Swiss quick-release standard, so it slides directly into any Arca Swiss-compatible clamp. It is also compatible with the DJI RS 2/3 quick-release system.
Does this collar mount work with lens adapter rings?
It supports lens adapter rings with a diameter under 63mm. If your adapter ring has a bracket attached, you will need to remove the bracket before installing the collar mount.
Can I use this mount on a gimbal stabilizer?
While physically compatible with some gimbal systems, Neewer does not recommend using the CA021 on a gimbal due to potential balance issues caused by the added weight and offset.
