Hi guys. I could do with some expert advice. I've been using the G1 for a few years and looking around here in Oz the G5 and G6 are going reasonably cheap second hand, a few anyway and only lightly used, and I was wondering what those in the know think. I looked at some second hand GH models but I get the impression they are worn out on video, which I don't need anyway, and those that aren't keep their price for the video. I would be using it almost exclusively for macro. Are the later G5 and G6 really much different to the old G1, or would I just be looking for something different sooner than later? Which one would you get, if either, and what differences could I expect to see?
