The D2Xs was unveiled 4 years prior to the 645D which is quite a significant gap as far as tech is concerned. Each of these cameras come with the identical body type (Large SLR).

Before delving in to a detailed comparison, below is a brief highlight of how the D2Xs matches up against the 645D in regards to portability, imaging, features and an overall mark.

Here is a sample of the gallery pics for Nikon D2Xs and Pentax 645D. The full galleries are viewable at Nikon D2Xs Gallery and Pentax 645D Gallery.

For anybody who is going to travel with your camera, you have to consider its weight and proportions.

Oftentimes, its tough to visualise the contrast between sensor dimensions only by looking at technical specs. The pic below will provide you a clearer sense of the sensor sizes in the D2Xs and 645D.

As you can tell, both the cameras have got different megapixel count and different sensor dimensions. The D2Xs using its tinier sensor will make shooting shallow DOF tougher and the Pentax 645D will give you greater detail having an extra 28 Megapixels. Greater resolution can also enable you to crop images much more aggressively. The more aged D2Xs is going to be disadvantaged with regard to sensor tech.
