Need help new body G1/GH1/GH2
The early reviews mention very fast focus and better high ISO performance for the GH2 (but you knew that). The GH1 will probably be around for a bit, so waiting for better reviews makes sense if you can wait. And then determine if the performance gain is worth the money.
I needed to make my purchase and got the just out G-2 and bought the 14-140 on eBay. If I had been able to wait until now, I'd probably have purchased the GH1 with the 14-140 and saved a bunch of money. I also bought the 9-18, so could live without the 14-42.
