Pentax K-3 vs Pentax K100D S

Lets look much closer at the Pentax K-3 versus Pentax K100D S, one being a Advanced DSLR and the latter is a Entry-Level DSLR and they are both sold by Pentax. There exists a huge gap among the sensor resolutions of the K-3 (24MP) and K100D S (6MP) but they come with the exact same sensor sizing (APS-C).

Remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you are working with at that time. Here is the front view measurements comparison of the K-3 and the K100D S.

Taking into account dimensions and weight, the portability rating of the K-3 and K100D S is 59 and 65 respectively.

Normally, it is tough to visualise the difference in sensor measurements purely by looking through a spec sheet. The visual below may give you a much better sense of the sensor measurements in the K-3 and K100D S.

As you can see, both of those cameras have got the exact same sensor measurements albeit not the same MP. You should expect the Pentax K-3 to provide you with more detail as a result of its extra 18 Megapixels. Higher resolution will also let you crop photographs much more aggressively. The younger K-3 is going to have an edge when it comes to sensor innovation.
