Sometimes, it's difficult to envision the difference between sensor dimensions merely by checking specifications. The image underneath may offer you a greater sense of the sensor sizing in the G100 and K-3 II.

Plainly, each of these cameras have got different megapixels and different sensor dimensions. The G100 having a tinier sensor will make shooting shallow depth of field trickier and the Pentax K-3 II will resolve more detail because of its extra 4 Megapixels. Greater resolution will also allow you to crop photos much more aggressively. The newer G100 is going to have an advantage when it comes to sensor innovation.
