The 1s was manufactured 4 years later than the K-5 and that is quite a significant difference as far as tech is concerned. Both of these cameras feature different body design with the Olympus 1s being a SLR-like (bridge) camera and the Pentax K-5 being a Mid-size SLR camera.

Before delving straight to a complete comparison, here is a quick summary of how the 1s matches up vs the K-5 with respect to portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Olympus Stylus 1s & Pentax K-5. The entire galleries are viewable at Olympus 1s Gallery & Pentax K-5 Gallery.

In many cases, it's tough to imagine the difference between sensor sizing purely by reading through a spec sheet. The graphic below will provide you a much better sense of the sensor sizes in the 1s and K-5.

Clearly, the 2 cameras come with different resolutions and different sensor sizing. The 1s featuring a tinier sensor is going to make shooting shallower depth of field more difficult and the Pentax K-5 will give you extra detail due to its extra 4MP. Higher resolution can also make it easier to crop pictures a good deal more aggressively. The fresher 1s should have an advantage with regard to sensor innovation.
