The Blender Auto Focus Camera Addon, developed by Wanderson M. Pimenta, adjusts your camera's focus automatically based on whatever sits at the center of your view. The result is depth of field without setting focus distance by hand. A toggle with a camera icon activates the system, and a refresh button restarts the auto focus timer if it stops responding.
Focus Transition Time controls how smoothly focus shifts between objects, ranging from an instant change to a gradual one-second transition, with 0.1-0.3 suggested for natural-looking results. Optional bounce and breathing effects add a focus bounce and simulate lens breathing, each with their own strength settings. The Smart Focus system runs multi-point analysis across a grid and can prioritize objects in the center of the frame or those closer to the camera, with an optional grid overlay in the viewport.
Focus Offset lets you push the focus point forward or backward, and five keyframe buttons animate that offset. Because the addon works only in the Blender interface, a baking process writes focus keyframes for rendering. DOF settings cover F-stop, aperture blades, rotation, ratio and focus limits.
