Profoto Fight Night from S1 Group on Vimeo.

Profoto shows off their incredibly fast strobe refresh times on their new Profoto Pro-8a packs by inviting two professional MMA fighters to S1 Studios in Toronto, Canada and photographing them while they fight. The packs are able to recycle at an astonishing 8-10 frames per second so shooting on continuous burst is no problem for these packs.
