We have many Lumix cameras here and it works on all of them even the GH4's. So if you want a simple to use, low cost Lumix flash that takes only two AA batteries, this is your guy.This sale is just the flash you see in the photos. No manual, no box, no pouch - just the flash that has a few minor cosmetic scuffs from being carried in a backpack photo case for a year, but it's been fired only a few times (less than 300 flashes) and all the functions work like when it was new. With the great high ISO and low light performance of the Lumix cameras, this small, low guide number flash is sometimes just what you need and it's light weight means you'll have it on you when you need it.
