Pentax K-S2 vs Pentax K100D

Its time to look a bit more in depth at the Pentax K-S2 versus Pentax K100D, both Entry-Level DSLR cameras and both are designed by Pentax. There exists a sizable gap among the resolutions of the K-S2 (20MP) and K100D (6MP) but both cameras offer the same sensor size (APS-C).

The K-S2 was brought out 8 years later than the K100D and that is a fairly significant difference as far as camera technology is concerned. The two cameras have the same body design (Compact SLR).

Before we go right into a in depth comparison, here is a simple summary of how the K-S2 scores vs the K100D in relation to portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Pentax K-S2 & Pentax K100D. The entire galleries are available at Pentax K-S2 Gallery & Pentax K100D Gallery.

For anyone who is planning to lug around your camera regularly, you're going to have to consider its weight and dimensions. The Pentax K-S2 enjoys outer dimensions of 123mm x 91mm x 73mm (4.8" x 3.6" x 2.9") with a weight of 678 grams (1.49 lbs) whilst the Pentax K100D has dimensions of 129mm x 93mm x 70mm (5.1" x 3.7" x 2.8") accompanied by a weight of 660 grams (1.46 lbs).

Keep in mind, the weight of an ILC will differ based on the lens you are using during that time. Underneath is a front view over all size comparison of the K-S2 vs the K100D.

Considering dimensions and weight, the portability grade of the K-S2 and K100D is 64 and 64 respectively.

Sometimes, it's hard to visualise the contrast in sensor measurements simply by going through technical specs. The graphic below will provide you a far better sense of the sensor sizes in the K-S2 and K100D.

As you can tell, both the cameras have the same sensor dimensions albeit not the same megapixels. You can count on the Pentax K-S2 to produce more detail having its extra 14MP. Higher resolution can also enable you to crop photographs a bit more aggressively. The younger K-S2 is going to have an edge in sensor tech.
