The 1s was introduced 23 months after the Efina making them a generation away from one another. Each of the cameras have different body design with the Olympus 1s being a SLR-like (bridge) camera and the Pentax Efina being a Ultracompact camera.

Before diving into a full comparison, here is a simple view of how the 1s grades against the Efina with regards to portability, imaging, features and an overall mark.

Here is a sample of the gallery pictures for Olympus Stylus 1s and Pentax Efina. The whole galleries are viewable at Olympus 1s Gallery and Pentax Efina Gallery.

Normally, it is tough to see the contrast in sensor dimensions purely by researching technical specs. The image here may provide you a better sense of the sensor dimensions in the 1s and Efina.

As you can tell, both of those cameras provide different megapixels and different sensor dimensions. The 1s with its larger sensor will make achieving shallower depth of field simpler and the Pentax Efina will provide you with greater detail using its extra 2MP. Greater resolution will also let you crop pics more aggressively. The younger 1s is going to have an advantage in sensor technology.
