As you can see, both the cameras provide different megapixel count and different sensor dimensions. The K-7 with its bigger sensor is going to make getting shallower depth of field simpler and the Sony HX30V will produce more detail having an extra 3MP. Higher resolution will also help you crop shots more aggressively. The more aged K-7 will be behind in sensor innovation.
