Quite often, it is very difficult to visualize the contrast between sensor dimensions just by checking technical specs. The pic here may give you a greater sense of the sensor dimensions in the Efina and K-x.

As you can tell, both the cameras have got different resolutions and different sensor dimensions. The Efina with its tinier sensor is going to make achieving shallow depth of field harder and the Pentax Efina will give you extra detail using its extra 2 Megapixels. Higher resolution will make it easier to crop shots much more aggressively. The fresher Efina provides a benefit with regard to sensor technology.
