The large Elinchrom Rotalux 175 cm Octabox is highly recommended and popular amongst beauty and fashion photographers, as it produces catchlight which is quite vital and seeing that it's quite huge - photographers could use it as their only light source . Additionally, the Octabox also allows you to create a great folding beauty dish by simply removing the front inner diffusers and adding on one of the optional deflectors.

Also Note that the Speed Rings are not included.
