Neewer Speedlite TT560 iso_125 4D is a professional full-frameThe Neewer Speedlite TT560 looks like a modern TTL flash, but its actually a simple single pin flash with manual power settings. The good news is that you can use it on basically any camera with a hot shoe, though. Manual power output can be controlled in 8 steps, the head can tilt and swivel, and it has a built in line of sight remote sensor for use as part of a larger flash setup. On camera or off, not a bad little flash. In near new condition.
