The Profoto Zoom Reflector 2 is a smoother, more accurate reflector, with an integrated grid holder that accepts Profoto grids directly -- no more need for the expensive extra grid holder.
The light from the new reflector is smoother yet more precise; the fall-off is more even, the dynamic range bigger, the stray light almost completely eliminated.
An optional protection cap -- the Zoom Cap -- fits on top of the reflector, even if it's holding a grid or if the reflector is mounted on a lamp head.
