I'm looking to order a Better Beamer flash extender for my Sigma EF-530 DG Super flash however, I can't find which model would fit it. Anyone can point me to the right model?
According to this flashfinder, the FX-2 fits the EF-500 Super, but the 530 isn't listed.
The same site also has a fitting guide that lists dimensions and measuring instructions, though, and these seem thorough enough to double-check the fit.
Note - the site is really slow, so be patient.
