Panasonic G100 vs Pentax WG-3

Lets look closer at the Panasonic G100 and Pentax WG-3, one being a Entry-Level Mirrorless and the latter is a Waterproof by manufacturers Panasonic and Pentax. There exists a big gap among the sensor resolutions of the G100 (20MP) and WG-3 (16MP) and the G100 (Four Thirds) and WG-3 (1/2.3") come with different sensor measurements.

Considering dimensions and weight, the portability grade of the G100 and WG-3 is 81 and 90 respectively.

More often than not, its tough to visualize the contrast in sensor measurements purely by seeing a spec sheet. The graphic here will give you a much better sense of the sensor dimensions in the G100 and WG-3.

Clearly, each of these cameras posses different megapixels and different sensor measurements. The G100 with its bigger sensor is going to make achieving shallower DOF easier and the Panasonic G100 will produce more detail with its extra 4 Megapixels. Higher resolution will let you crop shots somewhat more aggressively. The newer G100 provides an edge in sensor technology.
