I just bought a new G2 off eBay (my first digital camera). I like synchro-flash technique, and have a Vivitar 285 that I use on my other cameras. My question, I have heard that using a non-Canon approved flash for this camera can damage it (voltage level or something), and that it requires a converter of some type to use 'other' flashes.
Can someone who is knowledgable fill me in on the facts regarding this?
Thanks in advance...
