Flash works well with my Panasonic Lumix FZ200 camera in TTL mode. I like the additional features of this device like tilt and swivel; built-in diffuser; TTL, automatic and manual mode; synchronization of the front and rear curtains; powerful scaling; Slave function, energy saving function. I also found an external flash cable that works with this flash and camera (Precision Design Heavy Duty Off-Camera Cord - Olympus TTL - RS-0448P). I'm waiting for the cable to arrive so haven't used it yet but it should work with this flash and camera. The only minor thing I noticed about the flash is that nothing happens when I press the light button and you have to move the diffuser to push the reflective plate out. It's minor and I really like the flash.
