More often than not, it can be tough to visualise the difference between sensor sizing just by checking specs. The photograph here may offer you a much better sense of the sensor dimensions in the SP-620 UZ and K-3.

All in all, each of these cameras come with different megapixels and different sensor sizing. The SP-620 UZ using its tinier sensor will make achieving shallower depth of field more difficult and the Pentax K-3 will resolve more detail using its extra 8 Megapixels. Greater resolution can also enable you to crop images a good deal more aggressively. The older SP-620 UZ is going to be disadvantaged when it comes to sensor technology.
