Olympus TG-320 vs Pentax E70 Sensor Comparison

In many cases, it can be difficult to visualise the contrast in sensor dimensions purely by viewing a spec sheet. The pic below should provide you a far better sense of the sensor dimensions in the TG-320 and E70.

Clearly, the two cameras posses the exact same sensor measurements but not the same resolution. You can expect to see the Olympus TG-320 to result in greater detail having its extra 4 Megapixels. Greater resolution can also enable you to crop photos somewhat more aggressively. The younger TG-320 will have an edge when it comes to sensor innovation.
