Flash new guy alert.. Hello everyone, I'm looking for a compact flash to pair with my olympus pen s. I've never bought a flash before and was looking for some suggestions. I have a big old flash that I was given, but I haven't really used it and its too bulky to carry around with me most days. I'm looking for something that has a sync port, not a hot shoe (no idea if most flashes have a sync port). If possible something that's kinda flat and runs horizontal to keep my olympus pen nice and compact. Looking for something relatively feature rich, but portability is key here. Also feel free to impart any flash wisdom, because I've got no bloody idea!
