Nikon D100 vs Pentax K-3

Below, we are looking at the Nikon D100 and Pentax K-3, both Advanced DSLR cameras by brands Nikon and Pentax. There exists a large gap among the resolutions of the D100 (6MP) and K-3 (24MP) but they enjoy the exact same sensor sizing (APS-C).

The D100 was released 12 years earlier than the K-3 and that is a fairly serious difference as far as camera technology is concerned. Both cameras come with the identical body type (Mid-size SLR).

Before going through a more detailed comparison, below is a short highlight of how the D100 scores versus the K-3 in terms of portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Nikon D100 & Pentax K-3. The complete galleries are provided at Nikon D100 Gallery & Pentax K-3 Gallery.

For those who are looking to lug around your camera frequently, you need to think about its weight and dimensions. The Nikon D100 features exterior dimensions of 144mm x 116mm x 81mm (5.7" x 4.6" x 3.2") along with a weight of 780 grams (1.72 lbs) whilst the Pentax K-3 has dimensions of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") along with a weight of 800 grams (1.76 lbs).

Do not forget, the weight of an ILC will change depending on the lens you use at that time. Here is the front view scale comparison of the D100 and the K-3.

Taking into consideration dimensions and weight, the portability grade of the D100 and K-3 is 58 and 59 respectively.

Typically, it is hard to picture the gap in sensor measurements purely by looking through a spec sheet. The visual below will provide you a more clear sense of the sensor sizes in the D100 and K-3.

As you can see, both of the cameras have got the exact same sensor measurements but different megapixels. You can anticipate the Pentax K-3 to result in extra detail as a result of its extra 18MP. Greater resolution will make it easier to crop photos much more aggressively. The older D100 will be disadvantaged when it comes to sensor tech.
