Hi All,
I've been crawling around the boards doing research for a while now, but this is my first post (of many more to come hopefully 
). Anyway, thanks for all the useful info so far...
I have a question I can't find a good answer for... It's regarding S-TTL flashes and compact cameras. Specifically, I have a Canon IXUS 100is (SD780) compact camera and I'm planning to get the Inon S-2000 strobe.
As I understand it, for S-TTL to function correctly, the camera must send a pre-flash. My concern is this - I have noticed that my IXUS 100is does not ALWAYS pre-flash. I can have the camera on exactly the same settings and depending on the lighting of the scene it will pre-flash or not. (Even when I have the flash set to always ON.)
I know that I can set everything to manual as a workaround, but I really like the idea of S-TTL.
How will the strobe handle the intermittent pre-flash? Am I missing something obvious here? Has somebody had experience with the Ixus 100is (SD780) and S-TTL?
Many thanks!
Anferney
