I'm considering upgrading from my current G6, which doesn't raise ISO when using an external flash (Nissin i40), always 160 albeit on auto, which results in underexposure or slow shutter speed (1/60s). I used to shoot the Oly EPL5 and it was way more clever. It also lets you choose min shutter speed when flash is used. I searched but they don't always list "small" improvements like this in the specs so I think I'd ask here, does the G7 know to raise ISO when using external flash? I'd also like to hear G7 owners share more about the changes that make practical improvements, those handy things that don't appear important enough for Panasonic to write. Thanks!
