Rectangular softbox for flash

[kartracer]

I purchased one of these from eBay and generally I'm pleased with it:

Is anyone aware of a similar (budget) product in rectangular form? There are plenty on eBay advertised as Bowens fit, but not sure if it could be adapted to use a similar ball-head and ring fitting as supplied with above?

Get one of these instead

Then you can buy cheapie S compatible boxes. Once they get much bigger than 60x60 the push fitting they have doesn't work so well.

I have a Nissin Di866 Mk II on its way. I intend to get a Bowens speedlight adapter from eBay, as suggested. What is the biggest softbox I can use with a flash like this? What would be the max size for a rectangular box, and square?

Nobody's answered your question yet because it's surprisingly hard to answer

Depends on the construction of the box, and modifiers you put on the flash and what you consider and acceptable falloff from edge to centre.

I've used an SB800 with a 100 x 70 softbox and it worked for what I wanted.

Thanks.
