Lets look more closely at the Pentax K100D S and Sony W830, one being a Entry-Level DSLR and the latter is a Ultracompact by manufacturers Pentax and Sony. There is a huge difference among the resolutions of the K100D S (6MP) and W830 (20MP) and the K100D S (APS-C) and W830 (1/2.3") come with different sensor sizing.

The K100D S was unveiled 7 years before the W830 and that is a fairly significant gap as far as camera tech is concerned. Both cameras come with different body type with the Pentax K100D S being a Compact SLR camera and the Sony W830 being a Ultracompact camera.

Before we go in to a full comparison, below is a concise overview of how the K100D S matches up vs the W830 in terms of portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Pentax K100D Super and Sony Cyber-shot DSC-W830. The full galleries are provided at Pentax K100D S Gallery and Sony W830 Gallery.

If you are aiming to lug around your camera often, you are going to need to take into account its weight and proportions.

Don't forget, the weight of an Interchangeable Lens Camera will change dependant on the lens you are utilising at that time. Following is the front view measurement comparison of the K100D S versus the W830.

Taking into account size and weight, the portability grade of the K100D S and W830 is 65 and 96 respectively.

Usually, its difficult to imagine the contrast in sensor measurements merely by going through a spec sheet. The visual below will give you a more clear sense of the sensor sizes in the K100D S and W830.

As you can see, both cameras posses different megapixels and different sensor measurements. The K100D S having a bigger sensor is going to make shooting shallower DOF less difficult and the Sony W830 will produce more detail having an extra 14 Megapixels. Higher resolution can also help you crop photographs somewhat more aggressively. The older K100D S will be disadvantaged in sensor technology.
