Sturdily built with 16 fiberglass rods and an 8mm aluminum shaft this umbrella is well-suited to shooting large groups; offering fill light and long throw use. The parabolic shape and depth give the benefit of broad coverage coupled with a fair degree of directional control and a certain crispness.
