Description
The SmallRig 4633 LA-O90 Octagonal Softbox is a 90 cm octagonal light modifier for photographers and video makers who want softer, more controlled light from a Bowens mount setup. It suits studio work, product shots and interviews where a larger light source helps reduce harsh shadows and shape the light more evenly.
It opens to 900 x 450 mm and folds down to 760 mm for storage. The honeycomb grid is 45 degrees, with a 830 mm grid size, and the softbox weighs 900 g net. It uses a quick-release design, a standard Bowens mount and Oxford diffuser material. Materials include nylon, polyester, aluminium, iron, zinc alloy and stainless steel.
In use, it attaches to Bowens mount COB lights, including SmallRig RC 120D, RC 120B, RC 220D, RC 220B, RC 350D, RC 350B, RC 450D and RC 450B. It comes with the octagonal softbox, inner diffusion cloth, outer diffusion cloth, honeycomb grid, operating instructions and a storage bag. The grid helps narrow the spread of light when needed.
