Panasonic G2 vs Pentax K-S1

Following is a complete comparison of the Panasonic G2 and Pentax K-S1, former is a Entry-Level Mirrorless while the latter is a Advanced DSLR by companies Panasonic and Pentax. There exists a large gap between the sensor resolutions of the G2 (12MP) and K-S1 (20MP) and the G2 (Four Thirds) and K-S1 (APS-C) offer different sensor dimensions.

The G2 was revealed 5 years earlier than the K-S1 which is quite a serious difference as far as technology is concerned. Both of the cameras feature different body design with the Panasonic G2 being a SLR-style mirrorless camera and the Pentax K-S1 being a Mid-size SLR camera.

Before getting straight to a complete comparison, here is a concise view of how the G2 matches up against the K-S1 in the way of portability, imaging, features and an overall score.

When you are planning to carry around your camera frequently, you will have to factor in its weight and size.

Always remember, the weight of an ILC will vary dependant on the lens you are utilising at the time. Underneath is a front view over all size comparison of the G2 against the K-S1.

Considering dimensions and weight, the portability grade of the G2 and K-S1 is 72 and 69 respectively.

Typically, it is very tough to visualize the gap between sensor sizes purely by checking specifications. The image below may offer you a clearer sense of the sensor dimensions in the G2 and K-S1.

To sum up, both cameras come with different megapixel count and different sensor sizes. The G2 with its tinier sensor is going to make achieving bokeh more difficult and the Pentax K-S1 will give you more detail because of its extra 8MP. Higher resolution will make it easier to crop photographs a good deal more aggressively. The more aged G2 is going to be behind in sensor technology.
