Panasonic G3 vs Pentax K-70

Lets look a little more in depth at the Panasonic G3 and Pentax K-70, former being a Entry-Level Mirrorless while the other is a Entry-Level DSLR by rivals Panasonic and Pentax. There is a sizable difference among the image resolutions of the G3 (16MP) and K-70 (24MP) and the G3 (Four Thirds) and K-70 (APS-C) come with different sensor sizing.

The G3 was announced 5 years before the K-70 and that is a fairly significant difference as far as camera tech is concerned. Both of these cameras come with different body type with the Panasonic G3 being a SLR-style mirrorless camera and the Pentax K-70 being a Compact SLR camera.

Before delving through a full comparison, below is a quick overview of how the G3 matches up against the K-70 for portability, imaging, features and an overall grade.

When you are planning to lug around your camera regularly, you are going to need to think about its weight and measurements.

Keep in mind, the weight of an ILC will differ dependant on the lens you select at the time. Underneath is the front view dimension comparison of the G3 vs the K-70.

Looking at size and weight, the portability score of the G3 and K-70 is 83 and 62 respectively.

Often, it's hard to visualize the gap in sensor measurements merely by checking out specs. The graphic below may offer you a far better sense of the sensor sizing in the G3 and K-70.

All in all, each of the cameras posses different megapixels and different sensor measurements. The G3 using its smaller sensor is going to make achieving shallower depth of field trickier and the Pentax K-70 will produce more detail with its extra 8 Megapixels. Greater resolution can also let you crop images somewhat more aggressively. The older G3 will be behind in sensor innovation.
