Taking my first stab at using an off camera flash....I already had an external Sony HVL-36 FM flash, I mean speedlight LOL, that was wireless compatible but my Sony a9 doesn't have a built in wireless flash controller...after having fun researching what i needed, I found a suitable controller (Sony HVL-F20M) on Amazon warehouse that did the trick...it was listed a 'Very Good' condition and was $70 off the brand new price of $148...
I just hand held the external flash while taking this pic...it definitely changes the mood of the pic....Now I just need to figure out how to work the distance settings...Since both flashes are part of the Sony wireless flash function, it does pass exposure data to control the flash (so it isn't just a simple slave mode flash that fires full power every time)...
