Panasonic G3 vs Pentax E70

The following is a in-depth comparison of the Panasonic G3 and Pentax E70, former is a Entry-Level Mirrorless while the other is a Small Sensor Compact by companies Panasonic and Pentax. There is a substantial difference among the sensor resolutions of the G3 (16MP) and E70 (10MP) and the G3 (Four Thirds) and E70 (1/2.3") come with totally different sensor measurements.

The G3 was announced 2 years after the E70 which is a fairly big difference as far as camera tech is concerned. Both the cameras come with different body type with the Panasonic G3 being a SLR-style mirrorless camera and the Pentax E70 being a Compact camera.

Before diving through a full comparison, below is a simple overview of how the G3 grades against the E70 with regard to portability, imaging, features and an overall mark.

Often, it is difficult to visualise the contrast in sensor dimensions only by researching a spec sheet. The image below may provide you a more clear sense of the sensor sizing in the G3 and E70.

As you can see, the two cameras have got different megapixel count and different sensor dimensions. The G3 using its larger sensor will make achieving shallow DOF simpler and the Panasonic G3 will render extra detail with its extra 6 Megapixels. Greater resolution will also allow you to crop pics much more aggressively. The newer G3 is going to have an edge in sensor tech.
