The P70 was introduced 11 months prior to the TX5 and they are both of a similar generation. Both the cameras offer the identical body type (Ultracompact).

Before we go in to a in depth comparison, below is a concise introduction of how the P70 scores vs the TX5 when considering portability, imaging, features and an overall grade.

Normally, it is tough to visualise the difference in sensor measurements only by going through technical specs. The photograph underneath should give you a much better sense of the sensor sizing in the P70 and TX5.

As you have seen, both of those cameras offer different megapixels and different sensor measurements. The P70 having a larger sensor will make shooting shallower depth of field simpler and the Pentax P70 will produce more detail using its extra 2 Megapixels. Greater resolution will make it easier to crop photos a little more aggressively. The older P70 will be disadvantaged in sensor tech.
