可唔可以簡介一?以下四支閃燈之主要功能分別呢？

(EF-Sigma 500 ST 、EF-Sigma 500 Super 、EF-Sigma 500 DG ST 、 EF-Sigma 500 DG Super )

如用於 Canon 350D，邊支最合適呢？

多謝各位師兄師姐提點....... ^^

Only the "Super" is suitable for ETTL of 350D, I still cannot figure out the difference between the DG & the non DG, because I have not used the nonDG version, all of my friends have the DG version

係唔係已冇 non-DG 賣?
我諗應該一樣既啫, 加個 DG 係為左同鏡頭"同步"掛?
