Below is a in depth review of the Pentax K-x and Pentax K100D S, both Entry-Level DSLR digital cameras and both of them are manufactured by Pentax. There exists a huge gap between the sensor resolutions of the K-x (12MP) and K100D S (6MP) but both cameras provide the same sensor size (APS-C).

The K-x was manufactured 2 years later than the K100D S and that is quite a significant gap as far as technology is concerned. Each of these cameras have the same body design (Compact SLR).

Before we go right into a complete comparison, here is a quick summary of how the K-x scores vs the K100D S for portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Pentax K-x and Pentax K100D Super. The entire galleries are viewable at Pentax K-x Gallery and Pentax K100D S Gallery.

For anyone who is planning to lug around your camera often, you will have to take into account its weight and measurements. The Pentax K-x features exterior dimensions of 123mm x 92mm x 68mm (4.8" x 3.6" x 2.7") with a weight of 580 grams (1.28 lbs) whilst the Pentax K100D S has proportions of 129mm x 91mm x 71mm (5.1" x 3.6" x 2.8") accompanied by a weight of 646 grams (1.42 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you are utilizing at the time. Below is a front view size comparison of the K-x versus the K100D S.

Looking at dimensions and weight, the portability grade of the K-x and K100D S is 69 and 65 respectively.

More often than not, it is very hard to envision the difference between sensor measurements purely by reading through technical specs. The visual below may offer you a stronger sense of the sensor sizes in the K-x and K100D S.

As you have seen, both of the cameras have the same sensor dimensions but not the same resolution. You should anticipate the Pentax K-x to give you extra detail due to its extra 6MP. Greater resolution will also enable you to crop pics a bit more aggressively. The fresher K-x will have an edge when it comes to sensor innovation.
