got this from all DIMAGE
The two Sigma flashes, the EF 500 DG ST and the EF 500 DG Super, are good news for DiMAGE 5/7/7i//Hi owners.
DiMAGE owners can now choose system flashes from three manufacturers: Minolta, Metz and Sigma.
The two new Sigma models will be available in December.
The ST model is the entry level flash that will compete with the Minolta 3600 HS(D). It is a powerful flash and has all basic features that are needed. The Super model will compete with the likes of Minolta 5600 HS(D) and Metz MZ54. It supports wireless operation and has flexible manual settings.
Sigma specify that the AF assist lamp is supported but I suspect this is only for the Maxxum, not for the DiMAGE's.
