This is the Elinchrom Rotalux Octa Softbox 100cm (39'') Reflective Cloth Only 
Rotalux Octa softboxes are very popular among beauty and fashion photographers, as they prefer the round catchlight given by these softboxes. You can make yourself a great folding beauty dish just by removing the front and inner diffusers and adding one of the optional deflectors. The easy mounting Rotalux system is probably the most widely copied of all softbox systems. However, it is easier to copy a design than a quality and they remain the best units in their class. They are lightweight and unlike many other softboxes, fold down just like an umbrella and can be easily stored in the included carrying bag. The quality of light is outstanding because of their construction and the internal diffuser provides the softest and most even light possible. The optional deflector set takes advantage of the unique Elinchrom central shaft to modify the softness/hardness and colour like no other softbox system.
