I just received my little 220EX, today, from Vistek in Toronto. I can't get over how small it is and seems to be a good match for the G6. Yes, many of you will say "Why not the 420EX?"
I already have the large 540EZ for my EOS gear, and, if I need to use a powerful flash, chances are it will be for something that requires a lot of proofs and film is the better answer to those needs, plus I can go as wide as 20mm with my EOS system. There are times and places for film technology, despite how much I enjoy using the G6.
I was very pleasantly surprised to see the "made in Japan" monicker on the 220EX, as I assumed it would not be a Canon Japan item. It is nicely built and tough as nails, uses 4 AA cells for fast recycling and longer battery life, and comes with an attractive and functional soft leather case. I tried out some shots using the fill-flash ratio setting on the G6 to -2/3 of an f/stop, and it seemed to work very well. I'll be using this for outdoor fill-flash situations where I'm relatively close to the subject. Of course, if I want to take 'snapshots' that are better than the average ones with the built-in flash, I can do that.
I will do some further testing including using the Off-Camera Shoe Cord and a bracket.
