Let me start off by saying that I really like my G5. In fact the more I use it the more I like it. But I have run into some issues that I would like addressed when I buy my next camera. First, I'd like better high ISO performance. I know this isn't a strength of the M43 system, but I would like an improvement there. Next, I'd like better AF-C tracking. I know, not a mirrorless strong suit, but manufacturers are making strides there as well. Finally, I'd like a bigger buffer for so I can take more shots before it fills up and a quicker processor so the buffer clears faster when it does get full. I know the GH4 has better tracking and a bigger buffer, I'm not sure about better high ISO performance. I'd prefer those features in a body more the size of the G5 than the GH4, but perhaps I am wanting too much. What do you think the odds are there will even be a G7 and if there is, that it will address those areas? Outside of those issues, however, the G5 is about perfect for me. And I can work with those limitations. Cheers.
