The ideal soft box on location. The Deep Octa 70 cm is an excellent crispy and direct light when used without the internal and external diffusers. Perfect for beauty and fashion. The narrow shape reduces the spread of light and offers sharper shadows compared to standard sized octagonal soft boxes. Another innovative feature which distinguishes Elinchrom soft boxes from others is the lightweight dedicated speed ring, which utilizes knurled, spring-action sockets to connect the stainless rods which form the frame of the box, to the ring. This allows easy assembly of the box in a de-tensioned state. The user then simply pivots the sockets 90 degrees until they lock into place to tension it for use. As a further convenience Elinchrom provides a durable, dot-patterned nylon case with a flat bottom designed to hold the de-tensioned Rotalux without dissembling it. The 27.5" (70 cm) Deep Octa shape features a large surface area which renders a "wrap-around" light quality especially when used at close range. It is ideal portraiture. Quick Setup, Breakdown Lightweight, dedicated speed rings utilize knurled, spring-action sockets to connect the 8 stainless rods which form the frame of the box.
