Collapsible Telescopic Flash Diffuser

I wanted to maximise the soft light from my flash gun but had to be able to easily move the light source around with me, so a brolly or softbox was not viable. I therefore decided on a large diffuser, that also utilises bounced light from any walls or ceilings. This telescopic diffuser compacts down to fit in a camera bag with it's own protective case to avoid being crushed when on the move.

The diffuser fits my Yongnuo 565EX flash, but I believe that it will fit some other models too. Havin
