Coming from a 60D with a Speedlite 430EX and want something similar in function for the GX7. Looks like the FL-360L is the default choice, but I also hear a lot about the new NIssin i40. I just have a hard time paying $40 more for a third party flash, even if it is an inch shorter. Anything else I should look at? This is just for indoor bounced flash family pics. I do plan to use it via wireless E-TTL occasionally on an umbrella stand.
