Panasonic ZR3 vs Pentax K100D S Sensor Comparison

Typically, it is very difficult to envision the gap between sensor measurements only by reading specs. The photograph underneath will give you a more clear sense of the sensor dimensions in the ZR3 and K100D S.

All in all, the two cameras have different megapixel count and different sensor measurements. The ZR3 having a tinier sensor will make shooting shallower depth of field more challenging and the Panasonic ZR3 will deliver extra detail using its extra 8MP. Greater resolution will let you crop photos a bit more aggressively. The younger ZR3 is going to have an advantage with regard to sensor innovation.
