Sony G3 vs Sony A58 Sensor Comparison

Typically, it is hard to envision the gap between sensor measurements merely by checking a spec sheet. The photograph below might give you a stronger sense of the sensor sizes in the G3 and A58.

Clearly, both of those cameras feature different resolutions and different sensor measurements. The G3 using its tinier sensor will make achieving shallower depth of field more difficult and the Sony A58 will give you greater detail because of its extra 10 Megapixels. Greater resolution will also allow you to crop images way more aggressively. The older G3 is going to be disadvantaged with regard to sensor innovation.
