Normally, it's hard to picture the difference between sensor dimensions merely by checking specifications. The image here will help give you a stronger sense of the sensor measurements in the K-7 and RS1500.

Plainly, both of the cameras provide different megapixels and different sensor dimensions. The K-7 using its bigger sensor is going to make achieving shallower depth of field easier and the Pentax K-7 will resolve greater detail because of its extra 1MP. Higher resolution will also let you crop shots more aggressively. The more aged K-7 is going to be disadvantaged in sensor technology.
