The Hanimex X140 is a small-sized external flash that will work on any camera that has a hot shoe attachment. All you have to do is to pop it on the hot shoe attachment, wait for it to charge (you'll hear a little whine whilst it's powering up), set your camera to flash mode and when you press the shutter button, the flash flashes!
Battery: 2x AA
Fully tested, 100% working
