On est d'accord
Sinon dans le test je viens de lire :
"Update 25th Feb 2013
I probably should have made it clearer that the head can only be used in HSS mode when it's set to full power. This means what you get, in terms of light power, is what you get, so you need to adjust your aperture to take up the slack, so to speak. Also, and this may not be immediately obvious, the guide number will drop as the shutter speed is increased beyond 1/250th second, so at 1/500th second the effective guide number will drop from 42m to about 30m and so on and so forth, so at 1/8000th second you'll be down to a GN of about 7.5m. Which is not going to light too much up in all honesty. "
En gros le HSS fonctionne qu'à pleine puissance !
