Safe to use Canon Speedlite 166A on Canon S5is?
I have a Speedlite 166A that I used a few times on my Canon S5is,
until someone told me I could damage the camera with it. I quit using it, but is it really unsafe to use on this camera? The recommended flashes are 220EX, 430EX, 580EX. Thanks Steve |

If it's 8 volts or less, 5 volts usually, then you're probably safe. Those warning are normally about very old studio flash units that typically have 80 volts or higher on the triggering contacts. According to this list http://www.botzilla.com/photo/strobeVolts.html It sounds like that flash is perfectly safe with 4.33v. That's what you get for listening to the advice of a bunch of arm-chair photographers and resident trolls that infest this newsgroup. ....Interesting, the G7 doesn't like anything higher than 6 volts. |

If the recommended externals include Canon's own 430 and 580EX models, that strongly suggests that the camera will benefit from the advanced electronic feedback connection between the flash and the camera. Now, these are not cheap flashes; I have the 430EX and I recall that it cost some $450-500 when I bought it 2 years ago (likely far less now), but I'd personally rather spend the $$$ and not only eliminate ANY risk to the camera and to gain the many advantages to Canon's newer camera-flash TTL system.
