I've decided to get a new camera body to accompany my gx7. It's to prevent changing lens during picture taking. I read around the interwebs that the gf6 uses the same battery as the gx7, DMW-BLG10 or BLE9. Using the same battery is definitely an advantage right? I will be able to use the same charger, bring along the same battery in the bag. Seems hassle free. Is this like a correct way to choose a 2nd camera body? As for the gf6 itself, does it produce good image quality? Is the noise/low light as good as lets say, epm2 or epl5? I've never own the epm2 or epl5. Reading forum discussions from here and there, it seems like they are capable camera. Usually i keep iso max at 1600. Anybody use the gf6 and gx7 can give me your feedback?
