p.1 #1 · Quantum 2x2 With 580EX II - How do I know?
I have a Quantum 2x2 that I recently acquired, and I have it all charged up and connected to my 580EX II. It seems like it is working, but how will i know for sure that I am using the 2x2 instead of the AA batteries inside the flash? Also, I am using a 7D and I have the Canon off camera shoe cord 2. Will I still get ETTL configured this way and will it use the 2x2 as well?
