Pentax P70 vs Pentax S1 Sensor Comparison

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.
