Panasonic ZR3 vs Pentax K100D S

Let's take a closer look at the Panasonic ZR3 versus Pentax K100D S, former being a Small Sensor Compact while the other is a Entry-Level DSLR by manufacturers Panasonic and Pentax. There exists a considerable gap between the resolutions of the ZR3 (14MP) and K100D S (6MP) and the ZR3 (1/2.3") and K100D S (APS-C) provide totally different sensor measurements.

The ZR3 was introduced 2 years later than the K100D S and that is quite a large difference as far as technology is concerned. Both the cameras have different body design with the Panasonic ZR3 being a Compact camera and the Pentax K100D S being a Compact SLR camera.

Before delving into a detailed comparison, here is a concise view of how the ZR3 matches up against the K100D S in regards to portability, imaging, features and an overall grade.

Typically, it is very difficult to envision the gap between sensor measurements only by reading specs. The photograph underneath will give you a more clear sense of the sensor dimensions in the ZR3 and K100D S.

All in all, the two cameras have different megapixel count and different sensor measurements. The ZR3 having a tinier sensor will make shooting shallower depth of field more challenging and the Panasonic ZR3 will deliver extra detail using its extra 8MP. Greater resolution will let you crop photos a bit more aggressively. The younger ZR3 is going to have an advantage with regard to sensor innovation.
