I ordered the set in order to modernize the studio (as well as with the 30 * 120cm softbox) The Blitz: More power, more reliable and dimmable modeling (which is standard now). The 400 ws are amazing. To get as much light, very short loading times and no color change during continuous flash (at least not perceptible). I'm not that have been a fan of umbrellas, rather take a softbox or a styrofoam plate, but the screen was just time with this - and if you ever have to then .. The advantage is simply that he is in front of the flash , thereby taking away any space and is very flexible. To the result is like a styrofoam plate .. The stand is made of aluminum and thus light but acts still robust. The springs in the stand to prevent a complete penetrate, if you hold times forgets the flash. Outdoor games but, like all ALU tripods, not suitable because it is just too easy and would fall over at every gust.
