Olympus TG-610 vs Pentax K-x Sensor Comparison

More often than not, it can be hard to picture the gap between sensor dimensions purely by reviewing specs. The image underneath might give you a much better sense of the sensor sizing in the TG-610 and K-x.

All in all, the 2 cameras have different megapixels and different sensor dimensions. The TG-610 featuring a tinier sensor is going to make shooting shallow depth of field trickier and the Olympus TG-610 will deliver extra detail due to its extra 2 Megapixels. Greater resolution will also make it easier to crop photos a bit more aggressively. The younger TG-610 provides a benefit in sensor tech.
