Leica S2 vs Pentax 645D

Below, we will be reviewing the Leica S2 and Pentax 645D, both Pro DSLR digital cameras by manufacturers Leica and Pentax. The sensor resolution of the S2 (38MP) and the 645D (40MP) is pretty well matched and they feature the exact same sensor sizing (Medium format).

The S2 was manufactured 17 months before the 645D which makes the cameras a generation apart from each other. Both the cameras come with the identical body type (Large SLR).

Before going in to a in-depth comparison, below is a simple overview of how the S2 scores versus the 645D with regard to portability, imaging, features and an overall rating.

For anyone who is intending to carry your camera frequently, you should think about its weight and measurements.

In many cases, it is difficult to visualise the gap between sensor sizing merely by checking specs. The visual here should give you a more clear sense of the sensor sizes in the S2 and 645D.

As you can plainly see, each of these cameras have got the exact same sensor measurements albeit not the same resolution. You can expect the Pentax 645D to resolve more detail due to its extra 2MP. Higher resolution will allow you to crop shots much more aggressively. The older S2 is going to be disadvantaged with regard to sensor technology.
