This is a Photoflex X-Small LiteDome Kit 1. It is lightweight and portable. The included mounting hardware enables use of the 12 x 16" softbox with most shoe-mount flashes (except Sony-Minolta flashes). Add the optional Shoe Mount Multiclamp (AC-BSWCP) to provide tilt capability when using this kit with your light stand. The Photoflex X-Small LiteDome Q39 Softbox with white interior is suitable for use with flash only. With fabric not intended for the heat of a continuous light, the X-Small LiteDome with white interior is ideal for work in small spaces when only slight softening of your flash is desired. Because of its small size, light quality will be more spectral with a faster gradation from highlight to shadow areas -- when you back it off from your subject.
