Panasonic G1 vs Pentax K-S1

Lets look a bit more in depth at the Panasonic G1 versus Pentax K-S1, former being a Entry-Level Mirrorless while the latter is a Advanced DSLR by companies Panasonic and Pentax. There exists a large gap among the image resolutions of the G1 (12MP) and K-S1 (20MP) and the G1 (Four Thirds) and K-S1 (APS-C) feature totally different sensor sizing.

The G1 was released 6 years prior to the K-S1 and that is a fairly serious difference as far as camera technology is concerned. Both cameras come with different body type with the Panasonic G1 being a SLR-style mirrorless camera and the Pentax K-S1 being a Mid-size SLR camera.

Before going straight into a step-by-step comparison, below is a quick overview of how the G1 grades versus the K-S1 when it comes to portability, imaging, features and an overall rating.

Take into consideration, the weight of an ILC will differ based on the lens you have chosen at the time. Following is the front view scale comparison of the G1 versus the K-S1.

Typically, it is hard to see the contrast in sensor sizing only by looking through a spec sheet. The visual underneath will help give you a clearer sense of the sensor sizes in the G1 and K-S1.

Clearly, both cameras posses different megapixel count and different sensor sizing. The G1 featuring a smaller sensor will make shooting shallower DOF trickier and the Pentax K-S1 will provide you with greater detail as a result of its extra 8MP. Higher resolution will also help you crop shots somewhat more aggressively. The older G1 will be behind in sensor technology.
