    I'm learning E-TTL II on my Canon DSLR. How Av, M and P modes work during flash shooting. How it calculates flash strength with distance data, etc.

    How does the Oly m43 flash system work (is there a brand name to the Oly flash approach, like with Nikon's CPS or Canon's E-TTL II)? Does the Oly approach use distance data? Does it modulate flash strength automatically? Does it make a decision as to whether you are doing fill vs. main lighting flash, etc.

    Is the Oly flash system the same as the E-system flash approach?

    On a side note -- does Panasonic use the same flash system, or do they have their own?

    Any links that anyone knows about to Oly flash white papers would be much appreciated, too :)
