I didn't realize the A2 could use AAA. Thanks for the tip. I've been carrying an A2 for...wow, almost nine months now and I love the thing. My phone holster has a vertical tube in the back to use as a belt loop for horizontal carry, so I clip my A2 into it. Very handy.
I've also got a yearning for the
EOS A4 as it is only a touch bigger than the A2, but I'm not sure it's the best way to get into the world of CR123 lights.
