I have I question: Do you have a tip for a good softbox that works with my 430EX ii, 580EX ii, and 600EX RT? The way I intend to use it most, is to place the flash and softbox on a monopod to get portaits outside, so the softbox must not be so big that a person cannot hold it for a resonably timespan.
What's wrong with the vanilla commercial softboxes? Look @amazon, their weight is between 500-1500g (depending on size). Your only problem might be that they consume much flash power so the 430ex2 could be underpowered for daylight outdoor shots.
Good tip on the 430 being to weak for daylight shots.
Nothing wrong with the vanilla ones
but I wanted to be sure to buy one which is good and can be used with all three separate flashes. Nice if it is not too expensive too. I looked at one from Cowboy studio (after looking at another thread here) and it was in many ways a fit, however it seemed cumberstone to mount when outside.. I was thinking about the Ezybox by Lastolite, but in Norway it is quite stiff in price.
