Panasonic G5 vs Pentax K-S2

Below is a extended review of the Panasonic G5 and Pentax K-S2, former being a Entry-Level Mirrorless while the latter is a Entry-Level DSLR by companies Panasonic and Pentax. The resolution of the G5 (16MP) and the K-S2 (20MP) is pretty similar but the G5 (Four Thirds) and K-S2 (APS-C) possess totally different sensor sizes.

The G5 was brought out 3 years earlier than the K-S2 and that is quite a sizable difference as far as tech is concerned. Each of the cameras come with different body type with the Panasonic G5 being a SLR-style mirrorless camera and the Pentax K-S2 being a Compact SLR camera.

Before getting through a full comparison, below is a simple summation of how the G5 grades against the K-S2 in regards to portability, imaging, features and an overall grade.

When you are planning to lug around your camera, you have to consider its weight and measurements.

Remember, the weight of an ILC will change depending on the lens you have chosen at that time. Below is the front view measurement comparison of the G5 against the K-S2.

Taking into consideration size and weight, the portability score of the G5 and K-S2 is 74 and 64 respectively.

Often, it is very tough to envision the gap between sensor measurements only by going over technical specs. The graphic here will provide you a better sense of the sensor dimensions in the G5 and K-S2.

As you can tell, both cameras posses different megapixel count and different sensor measurements. The G5 due to its tinier sensor will make shooting shallower DOF more difficult and the Pentax K-S2 will deliver greater detail having its extra 4MP. Higher resolution will make it easier to crop shots somewhat more aggressively. The older G5 is going to be behind with regard to sensor tech.
