The 1s was launched 13 months later than the K-3 making the cameras a generation apart from each other. Each of the cameras come with different body type with the Olympus 1s being a SLR-like (bridge) camera and the Pentax K-3 being a Mid-size SLR camera.

Before delving in to a comprehensive comparison, below is a simple introduction of how the 1s scores vs the K-3 in regards to portability, imaging, features and an overall grade.

This is a sample of the gallery pics for Olympus Stylus 1s and Pentax K-3. The complete galleries are provided at Olympus 1s Gallery and Pentax K-3 Gallery.

In many cases, it is hard to envision the difference between sensor measurements only by looking at a spec sheet. The graphic below will help offer you a more clear sense of the sensor sizing in the 1s and K-3.

Clearly, each of these cameras have got different resolutions and different sensor measurements. The 1s due to its tinier sensor will make shooting shallow depth of field more difficult and the Pentax K-3 will give you more detail utilizing its extra 12MP. Greater resolution will enable you to crop photos much more aggressively. The more modern 1s is going to have an advantage when it comes to sensor tech.
