This add-on provides tools for adjusting camera perspective and framing while maintaining focus on a specific point in 3D space. It calculates the necessary camera repositions and perspective adjustments using exact math formulas to keep the camera focused on the 3D cursor.

The tool operates in Object mode and offers three primary modes: dolly-zoom, truckshift-x, and truckshift-y. In dolly-zoom mode, it alters both the field of view (FOV) angle and the camera's location. The truck-shift modes adjust the camera's shift and location. All these properties can be keyframed for animation purposes. It also supports a manual type-in mode, allowing users to input exact numerical values for adjustments, using either focal length in millimeters or FOV angle in degrees.
