Hi, After a positive Kickstarter launch the Sundisc backers are receiving their modifiers now.
They are similar to the Fstopper's 'Flash Disc', but at 60 cm they are larger. They are also deeper so that they can be used with any 6 in flange - including the 'S bracket' and derivatives.
Reviews should start appearing all over the Interweb shortly.
Their remarkable lightweight transforms booming a light out. It's easy to get a stand comfortably off to one side with just a strong swivel adapter and a short length of Alu 16mm rod. And the stand can be lightweight too.
So far, only snapshots . . .
