Nikon S100 vs Pentax K-S1

Here, we will be comparing the Nikon S100 versus Pentax K-S1, one being a Small Sensor Compact and the latter is a Advanced DSLR by manufacturers Nikon and Pentax. The sensor resolution of the S100 (16MP) and the K-S1 (20MP) is pretty well matched but the S100 (1/2.3") and K-S1 (APS-C) boast totally different sensor sizes.

The S100 was launched 4 years earlier than the K-S1 and that is quite a big gap as far as tech is concerned. Both of the cameras feature different body design with the Nikon S100 being a Compact camera and the Pentax K-S1 being a Mid-size SLR camera.

Before going into a full comparison, here is a simple highlight of how the S100 matches up against the K-S1 with respect to portability, imaging, features and an overall grade.

Usually, its tough to envision the gap between sensor measurements just by looking at specifications. The photograph underneath should give you a stronger sense of the sensor measurements in the S100 and K-S1.

Plainly, the 2 cameras come with different resolutions and different sensor measurements. The S100 because of its tinier sensor will make shooting shallow DOF trickier and the Pentax K-S1 will resolve greater detail utilizing its extra 4 Megapixels. Higher resolution will make it easier to crop shots a good deal more aggressively. The older S100 is going to be behind when it comes to sensor tech.
