My partner has given me a couple of old flashes that he used years ago, a Sunpak auto134 and Sunpak auto 3075 G, there is also a hot shoe to pc adapter. I have done a few google searches but I'm not sure if it is safe to use these with my new Canon Eos60D. From what I have read it is ok if used as a remote flash, but is the adapter safe to use?
Also does anyone know of a site I might be able to find a guide or manual on using them. Which one is better? What are the differences between the two?
I am a total newbie and really have no idea what I am doing so any advice is appreciated.
