Olympus TG-870 vs Pentax K100D Sensor Comparison

Oftentimes, it's difficult to visualise the contrast between sensor dimensions just by looking at technical specs. The pic here might provide you a greater sense of the sensor sizing in the TG-870 and K100D.

As you have seen, the 2 cameras posses different resolutions and different sensor dimensions. The TG-870 due to its tinier sensor will make shooting shallow depth of field trickier and the Olympus TG-870 will give you extra detail as a result of its extra 10MP. Higher resolution can also let you crop shots somewhat more aggressively. The younger TG-870 is going to have a benefit in sensor innovation.
