The Profoto Zoom Reflector 2 is a smoother more accurate reflector with an integrated grid holder that accepts Profoto grids directly with no more need for you to purchase the expensive extra grid holder.
The light from the reflector is smoother yet more precise and the fall-off is more even as well. It offers a more dynamic range. Stray light is almost completely eliminated .
The Zoom Cap, which is an optional protection cap, fits on top of the reflector, even while it's holding a grid or if the reflector is mounted on a lamp head.
