Wolkku 0 #1 November 26, 2010 Hi, I just noticed that Sigma has announced few months ago new flash that seems to be good competitor for Canon 580EXII. Has anybody tried that in skydiving yet? http://www.sigmaphoto.com/shop/ef610-dg-super-sigma Is it working in ff as well as canon? Price is much lower than 580 and if it works equally, I think I'm trying that one. Or should I stick with 580? Any opinions? Quote Share this post Link to post Share on other sites
