I was looking at an Olympus E-PL1. I only want it for portraits. Outdoor and indoor. But I want to use generic "slave" flashes like the once from Yongnuo. Will the Olympus take the radio control and allow me to trigger external flashes like for a softbox, umbrella, etc.? side question: Is an E-PL1 too old to consider? I can't afford very much and found them used with a lens for about $215. Thanks. edit: lens is 14-42 the "kit" lens, I believe.
