Here is the first image of the upcoming Panasonic GF7 that leaked out on Digicame-info. The new camera is the successor the Panasonic GF6 and is believed to sport a 16MP sensor, ISO 200-25,600 sensitivity and a 180º tilting LCD.
That’s the 12-32mm lens on the front that ships as a kit lens for the GM1 and GM5, which suggests that this camera will be very compact. Below is a photo of the GM1 next to the Canon G12 compact camera for sense of scale.
So, yeah, it looks like the GF7 will be on par with the GM1 in terms of body size.
