Lastolite Skylite Rapid Fabric Medium 1.1 x 2m, 0.75 Stop Diffuser

On a two-metre frame a light diffusion goes a long way: the panel is large enough relative to the subject that even three-quarters of a stop produces a broad, soft source without eating the exposure.

It clips into the medium Skylite Rapid frame and comes off just as fast, which is the reason the covers are sold apart from the frames at all. 0.36 kg, and it folds into the frame bag.
