The K-5 IIs was revealed 14 months earlier than the K-S1 which makes them a generation apart from one another. Both the cameras feature the same body design (Mid-size SLR).

Before getting into a complete comparison, here is a brief synopsis of how the K-5 IIs scores against the K-S1 with respect to portability, imaging, features and an overall rating.

This is a preview of the gallery photos for Pentax K-5 IIs & Pentax K-S1. The full galleries are viewable at Pentax K-5 IIs Gallery & Pentax K-S1 Gallery.

For those who are intending to carry your camera regularly, you will need to factor its weight and size.

Take into account, the weight of an ILC will differ depending on the lens you are utilising at that time. Underneath is a front view physical size comparison of the K-5 IIs and the K-S1.

Using dimensions and weight, the portability grade of the K-5 IIs and K-S1 is 60 and 69 respectively.

Typically, its hard to visualize the contrast in sensor sizing purely by checking out a spec sheet. The photograph here will provide you a much better sense of the sensor measurements in the K-5 IIs and K-S1.

Clearly, the 2 cameras feature the identical sensor size albeit different resolution. You can count on the Pentax K-S1 to produce more detail because of its extra 4MP. Higher resolution will help you crop pictures way more aggressively. The older K-5 IIs will be disadvantaged in sensor technology.
