Typically, it is very tough to see the contrast in sensor dimensions simply by looking through a spec sheet. The pic below might provide you a better sense of the sensor measurements in the 7040 and K-7.

Clearly, both of these cameras have different resolutions and different sensor dimensions. The 7040 due to its smaller sensor will make getting shallower depth of field more challenging and the Pentax K-7 will render greater detail as a result of its extra 1 Megapixels. Greater resolution will also let you crop images a bit more aggressively.
