As you can plainly see, both of the cameras feature different resolutions and different sensor sizes. The G3 using its smaller sensor will make achieving shallower depth of field more difficult and the Sony A7R will result in more detail using its extra 20MP. Higher resolution can also make it easier to crop photographs way more aggressively. The more aged G3 will be disadvantaged in sensor innovation.
