Rent the Elinchrom Rotalux 100cm Deep Octa. With its deep, octagonal design, the Rotalux Deep Octa 100 provides a focused, soft light. Perfect for portraits and more, as the softbox gives a round catchlight in the eyes and offers excellent control over light flow with its deep design. The Rotalux Deep Octa is highly popular among photographers because its light characteristics can be quickly and easily modified, from soft to hard, by removing the outer and, sometimes, the inner diffusion cloth.
