Title: Not for Canon PowerShot S5
Review: I bought this flash hoping to save $200 over the price of a Canon Speedlite 430ex. I attached it to my Canon PowerShot S5, and found that the camera was able to detect the external flash. I went to a dark room to experiment with the flash and found that it simply would not fire. I changed all the settings in the camera to no avail, the flash would simply not fire without pressing the "Test." After packing it back up and returning it, I went to go buy a Speedlite. Sure it costs a whole lot more, but the Speedlite is a much better flash than the Sunpak (perhaps because it actually works?).The packaging said that it works with Canon DSLR's, but some research shows that people simply can't get this flash to work with their cameras. Don't buy!
