The P70 was introduced 24 months earlier than the S1 which makes the cameras a generation away from one another. Each of these cameras offer different body type with the Pentax P70 being a Ultracompact camera and the Pentax S1 being a Compact camera.

Before getting in to a in depth comparison, below is a quick summation of how the P70 grades against the S1 for portability, imaging, features and an overall score.

The following is a preview of the gallery images for Pentax Optio P70 & Pentax Optio S1. The whole galleries are provided at Pentax P70 Gallery & Pentax S1 Gallery.

When you are intending to carry around your camera, you need to think about its weight and dimensions.

Quite often, its tough to visualise the contrast in sensor sizes purely by looking through specs. The picture here will give you a clearer sense of the sensor measurements in the P70 and S1.

All in all, both of the cameras offer the same exact sensor sizing albeit not the same resolution. You can expect the Pentax S1 to result in more detail using its extra 2 Megapixels. Higher resolution will let you crop pictures a little more aggressively. The more aged P70 will be disadvantaged in sensor tech.
