The D800 was introduced 3 years prior to the K-3 II and that is quite a big difference as far as technology is concerned. The two cameras feature the same body design (Mid-size SLR).

Before diving right into a comprehensive comparison, here is a concise summation of how the D800 grades vs the K-3 II with regard to portability, imaging, features and an overall grade.

If you are aiming to lug around your camera frequently, you have to take into account its weight and measurements. The Nikon D800 provides physical dimensions of 146mm x 123mm x 82mm (5.7" x 4.8" x 3.2") with a weight of 900 grams (1.98 lbs) whilst the Pentax K-3 II has proportions of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") with a weight of 800 grams (1.76 lbs).

Keep in mind, the weight of an ILC will change based on the lens you choose at that moment. The following is a front view sizing comparison of the D800 versus the K-3 II.

Taking into consideration dimensions and weight, the portability score of the D800 and K-3 II is 54 and 59 respectively.

Normally, it can be difficult to visualize the difference between sensor measurements just by going over specifications. The visual underneath should provide you a far better sense of the sensor dimensions in the D800 and K-3 II.

To sum up, both of these cameras come with different megapixels and different sensor measurements. The D800 using its larger sensor is going to make achieving bokeh less difficult and the Nikon D800 will offer you greater detail using its extra 12MP. Greater resolution will also allow you to crop images a good deal more aggressively. The older D800 is going to be disadvantaged when it comes to sensor technology.
