The DollyZoom command moves the camera location and changes the lens length at the same time, keeping the objects at the target plane about the same size.
Note: DollyZoom is effective in Perspective viewports only.
Click the left mouse button in the viewport and drag.
Note: When the cursor moves near the viewport corners, a snapping mode is enabled. The Lens length of the view camera snaps in 5 mm increments.
