I'm about to buy one of these off ebay. But I need to know more before clicking on the "buy" button. I have absolutely no idea how this flash works, or what it works with. All I know is that megaweb uses it for his macro shots. So, please tell me more !! Most important thing I wanna know is ...
1) Will it work as a cordless slaveflash with my on camera flash ?
2) Will it work on Nikon cameras or other old type (kiev, minolta rangefinders etc) cameras ?
3) How does it work ? Does it have a manual switches to control flash power ?
