>>3444272I don't know much about the GH3, but in my experience it is always better to have more lenses. Read up on them and determine if there is some feature that you can't live without on the G7. If so, buy it instead and save for lenses later. But if not, get the GH3 and the extra lens, which will allow you to take different types of photographs.
I have a G7, and the kit lens isn't bad, but it's not that great either. I later picked up the 25mm F1.7, which is very nice for portraits and video (in good lighting it's very good, in low light, acceptable but not great), and I also got the 45-150 which is a decent telephoto. Price was about $100-115 for both, got the telephoto used.
Also, are you sure you wanna go with MFT? There are other mirrorless cameras with bigger sensor.
